The program for speeding up the Internet is the best. Internet connection optimization Optimal Internet settings

Surely, each user has repeatedly experienced a sense of discomfort at moments, for example, watching a favorite movie on the Internet, when video playback stops abruptly and a buffering phenomenon is observed.

Freezing of the open page, unusually long loading of the site, disconnection of the connection - all this unpleasant consequences arising "congestion" on the way of transmission of information packets over the network.

Regardless of the type of connection, the methods that will be described here will in one way or another increase the speed of the Internet on windows 7, especially this article will be useful for mobile Internet users.

How to remove the internet speed limit?

Method 1: settings in the parameters of the serial port (COM1)

So, in order for us to find these parameters, we go to the device manager (Internet connection is not required now, the modem may be completely disabled): Start menu - Computer.

In the device manager, open the "Ports" item.

Here we select "Serial Port (COM1)".

Next in the window: Port parameters - in the "Bits per second" column, set the maximum value, confirm by clicking "Ok" and close all the tabs.

Method 2: tweak the reservation bandwidth limitation options

Let's start looking for options: Start menu - All programs - Accessories - Command line

In the command line, enter the command: gpedit .msc and press the Enter key.

In the menu that opens, look for the "Computer Configuration" item and open it.

Then open the following folders: Administrative Templates - Network - Qos Package Scheduler - Limit Reserved Bandwidth

In the window that appears, set a marker opposite the "Enable" item, and below in the "Bandwidth limitation (%):" column, enter the value - 0.

How to improve internet speed using software?

Method 3: increase internet speed with the Auslogics BoostSpeed utility

For this method, you need to download and install the Auslogics BoostSpeed program. This utility is available on the Internet as a free version, so you shouldn't feed the scammers! The program weighs only about 7 MB, we install it by default on the local drive C.

After installing the program, we reboot the system manually for the parameters to take effect. Before using the utility, we connect the Internet and go into it through the shortcut that appears on the desktop.

Here we are interested in the "Tools" section. By clicking on it in the new menu, we find the item "Internet Acceleration".

Under it, click on the "Automatic" button, select from three possible requests for Internet speed: fast, medium or slow, in accordance with your type of network connection, rearrange the marker, start the process through the "Analysis" button.

After checking, a list of all parameters that require optimization will appear on the screen, so we press “Optimize” and wait for the operation to end.

After that, a window will appear with a report on the work done and below the button "Restart".

Click on it, thereby restarting Windows to accept the new data.

What to do if your internet speed drops sharply?

Method 4: remove temporary files from Application Data

In Application Data (AppData folder), we only need one directory named "Temp". But to get to it, we need to first detect AppData, because it is a hidden system file.

To do this, we perform the following algorithm of actions: Start menu - Computer - Organize (button at the top of the window, on the left) - Folder and search options

Further view - in the window with additional parameters, we go down the list, find the item "Show hidden files, folders and drives", set the marker opposite it - a little higher in the list we find the column "Hide protected system files (recommended)" and uncheck the parameter - in the window with the warning, we put consent - "Yes" - click in the previous window with the parameters of the folders "Apply".

Thus, we have removed the protective effect of invisibility from hidden system files, some of them will be found on the desktop.

Having found this folder, click on the name with the right mouse button, find in the "Send" menu and click on "Desktop (create a shortcut)".

After all the steps, you can hide the system files again in the reverse order through the folder options. In this case, the "Temp" folder we need on the desktop will remain visible.

So what do we need the Temp folder for? When you start the browser, as well as when visiting various pages, blogs, sites, some temporary files from the network are delayed in the desired folder, which in turn slows down the data transfer. Therefore, having noticed a clear slowdown in page loading or a sharp drop in Internet speed, we should minimize the browser without closing it and enter the "Temp" folder.

In the "Temp" folder, select all the data and delete it using the Delete key or the right mouse button. Those files that will not be deleted are service files, the rest of the "trash" will be in the trash, which should be emptied immediately.

Many have faced this problem: “ slow Internet connection», Although subscribed to a fast tariff. There may be many reasons for this.

Such as:

no internet connection configured. This is the most common reason. Many do not even realize that the speed of the tariff is one thing, but how the computer will already use it is another. And here it is important to configure the network settings. This can be done manually, if you have the appropriate knowledge, or with the help of special software.
old operating system. It simply can no longer cope with modern data transfer rates, and it may not support some protocols. Yes, and a lot of rubbish from various software has accumulated in it, which also leaves its mark.
old browser. Yes, it is necessary to periodically update, only then they can work quickly and steadily and, moreover, safely.
old version of the program for downloading from the Internet. It can be, like, and.
infection with viruses or other malware. At the very least, you need to have a free antivirus and a firewall. Malicious software often goes online and sends or receives data.

Now let's talk about programs to speed up the Internet. And they are conventionally divided into the following groups:

Working with the cache... Everything is very simple here: when you go to a site, it is written to the cache of this program. And all subsequent times you do not load this site, but work through the cache. This creates an imaginary acceleration of the Internet. This approach is mainly used by firms to save money on traffic. At one time I also used this method. But then, with the advent of DSL, it disappeared on its own.
Software that optimizes network connectivity. They customize your computer. The Internet is actually not accelerating, of course, as you had, for example, 512 kb / s, so they stayed. Only now your computer is really using them 100%. This software also optimizes the operation of browsers, antiviruses and firewalls (provided they support such functions), optimizes the operation of network protocols, optimizes the operation of software such as skype (such programs as Active Speed, cFosSpeed and Speed Connect), improves online performance -games and much more.
Programs that configure browsers, email clients and other software for working with the Internet. In essence, they optimize the performance of other programs. These include: SpeedyFox.

Overclocking Dial-UP

How many times did you have to remember obscene epithets to your Internet connection? The usual thing. However, when it comes to network games (in particular, their Internet implementations), latency-sensitive gaming traffic sometimes becomes that drop that overwhelms the cup of patience, and we begin to seriously think about an expensive "leased line". However, with skillful tuning, even the latest noname-modem can be as fast as expensive "external" modems with excellent transmit / receive characteristics.

What is in our power is to provide high-quality wiring from the modem to the dashboard. And this is very important, because even small interference or "unreasonable" resistance can significantly reduce the speed. Internet connections due to the appearance of erroneous packages, the correction of which will require additional overhead. As a cable subsystem (we will use the terms SCS - structured cable system) it is recommended to use "twisted pair" - UTP category 5, unshielded. Shielded "twisted pair" is usually not used for telephone wiring, but if you have no choice, then it must be grounded. It should be recalled that any physical impact on the cable can lead to a change in its characteristics. Therefore, it is necessary to lay the line under the skirting board or in the boxes, avoiding strong bends.

The wiring in the apartment must be carried out in accordance with the figure. The main thing to take away from the diagram is that the telephone line must be connected directly to the modem. All telephones are connected to the line via a modem, and now the Internet will have the highest priority compared to "spoken devices". But this is not the most important thing. Our task is to eliminate any additional resistance that telephones create. All cable joints, the number of which should be minimal, must be soldered.

To avoid interference and pickup, you should run the cable no closer than 50 cm to the power lines if they run in parallel. When they intersect at right angles, then this is acceptable. It is also advisable to ground the system unit.

Provider, answer me!

Now we have a “perfect” cabling system and we need to move on to choosing a provider. This is perhaps one of the key points in Internet optimization. When a provider administers his own game server, then, connecting with him, it doesn't matter to us what channel he has from " outside world". In another situation, and it is the most common, this is almost the most critical parameter. Of course, it must be taken into account together with the number of users connecting to the provider and sharing the Internet bandwidth among themselves. Information about providers can be viewed, for example, on the website www.provider.net.ru.

As mentioned above, game traffic is very latency sensitive. For example, a familiar situation when you load some Quake 3 Arena, find like-minded people (gamers like you) and can't even hit the enemy from two meters away because until the information about your shot reaches the “enemy”, he will have time to hide. In this regard, when choosing a provider, you need to pay attention to such a parameter as MTU (Maximum Transmission Unit). This is the maximum block of data that is transmitted over the network and a packet larger than the provider's MTU will be fragmented, which will take longer to deliver useful information, and then provided that the provider is allowed to fragment ip packets (it should be noted that, as a rule, , it is allowed). Today's providers use switching equipment capable of independently adjusting the MTU size according to a given algorithm, which is adaptive. Therefore, it turns out that only the user can set a hard MTU. By the way, the user usually also has dynamic MTU selection enabled by default, but we will set it manually.

As for the choice of a provider, which is not entirely related to optimization, but rather simply to the possibility of reliable work on the Internet, then you need to pay attention to the status of the company, how many corporate buyers use its services, whether there are backup servers (mail, DNS, etc.) what hardware is installed and how wide the modem pool is. In general, all this adds up to how stable and quickly your Internet requests will be processed.

The insides of the OS.

"Shura, launch the Berlaga" (O. I. Bender)

Now is the time to get into the holy of holies of the OS - the system registry - and configure the local Internet settings. There can be a huge number of parameters, especially when you consider the tasks for which the application layer is implemented independently, and not by means of the OS. But we will look at the most basic parameters and those that can significantly affect online games and Internet speed. In Windows XP, developers tried to take into account such an important area of modern networks as quality of service (QoS - Quality Of Service). The fact is that the Internet channels are sometimes overcrowded, and traffic sensitive to delays (for example, voice or video) must be given a higher priority over normal data. This is exactly what QoS technology does. The developers of Windows XP began to reserve 20% of the bandwidth of the Internet channel for ensuring the proper quality of service (implementation of QoS RSVP - Resource Reservation Protocol). By the way, it should be said that QoS protocols do not work well on the Internet so far, and they are unlikely to be used in the foreseeable future, at least in Runet. Now in many newsgroups there is a myth that 20% of the bandwidth is reserved in any case and the percentage should be reduced to 0 or completely disabled QoS. An article has been published on the Microsoft website stating that QoS protocols work only with applications where this is programmatically implemented (during development, the QoS API was used). We can confidently assert that we will not find such applications on our home computer, because the development of such software products is only gaining widespread acceptance, and these projects are mainly aimed at supporting ip-telephony or expensive distributed ERP systems (or enterprise resource management systems), such as, for example, SAP R / 3. If you do not want the RSVP QoS protocol to work on your PC, then you can set the reserved bandwidth to 0% or disable this service altogether. We type gpedit.msc in the command line, go to Computer Configuration - Administrative Templates - Network - QoS Package Manager, select Limit Reserved Bandwidth. Double-clicking will display a window in which you need to enable quality of service, and limit the bandwidth to 0%. Next, you need to make sure that the QoS protocol is enabled. To do this, right-click on Network Neighborhood, then Properties, go to the Internet connection properties, the Network tab and find the QoS Packet Scheduler there. If the protocol is not there, then it needs to be installed. After completing these operations, restart your computer. If you want to disable the service, then go to Start> Settings> Control Panel> Administrative Tools> Services>

Now let's talk about the previously mentioned maximum data unit (MTU). The maximum packet in our switched networks, as a rule, is a data block of 1500 bytes. When using the Internet for gaming, the MTU needs to be small. The fact is that the larger the packages, the more time and overheads will be required for their delivery, and gaming traffic cannot afford such a luxury. Therefore, setting the MTU to 1500 bytes is excluded. On the other hand, if this parameter is too small, then a minimum of "useful" information will be transmitted, and a maximum of overhead data in the form of protocol headers and sync signals. This is also an extreme that should be avoided. The MTU for the Internet (when PPP is running) of 576 bytes is often referred to as the de facto standard. Therefore, we will not be the first to propose using this number for games. To do this, run regedit.exe and look for the next registry branch - HKEY_LOCAL_MACHINE \ System \ CurrentControlSet \ Services \ Tcpip \ Parameters \ Interfaces \ [Adapter ID]. There may be several adapters, and not all of them are real. Create an MTU dword parameter for each and specify a value equal to 576 in decimal notation. There is also a parameter MSS - Maximum Segment Size. This is the size of the data segment, which, together with the protocol headers, is the MTU. The size of headers is fixed and is generally 40 bytes. Therefore, it is not necessary to specify the size of the MSS, since with MTU = 576 bytes, the MSS is 536 bytes. If you still want to set the MSS value manually, then create the MSS key in the same registry branch.

There is an algorithm whereby two nodes can choose the MTU value themselves after exchanging their MSS values. This method is called Path Maximum Transmission Unit Discovery - The maximum transmission packet size for this path. To enable it, create the EnablePMTUDiscovery key in the registry branch HKEY_LOCAL_MACHINE \ System \ CurrentControlSet \ Services \ Tcpip \ Parameters and assign it the value "1", if we disable this algorithm, then assign it "0". The PMTU Discovery method has an extension that allows you to determine those routers that do not notify the host about packet loss if this happens due to the impossibility of their fragmentation (these routers are considered dead-end and are not used in the future). T.N. The Black Hole Detect algorithm is enabled by creating the EnablePMTUBHDetect key with the value "1" in the HKEY_LOCAL_MACHINE \ System \ CurrentControlSet \ Services \ Tcpip \ Parameters branch. It is advisable to turn off both of the above methods, since their work can significantly slow down the process of messaging on the network.

The next important parameter is the so-called "sliding window". Let's define the terms. A "sliding window" is a certain data buffer that is located at the receiving station and is filled by the source station with packets, the acknowledgment of receipt of which can be sent by the receiving station at any time, but no later than the data buffer overflows. Thus, packets sent by the source when the destination window is full will be discarded. In connection with the above, we determine that it is desirable to increase the window size for reliable lines, and decrease for bad ones. Again, the de facto standard for PPP (by which we work at the data link layer on the Internet) is a window size of 4288 bytes. If you have more or less reliable communication lines with the provider, then the specified size can be increased, but remembering that the window size must be a multiple of the MSS (for example, 5360 or 8040). This is to ensure that the window buffer is only filled with payload and is not reserved for smaller packets that it cannot accept. Look in the registry for the HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ Tcpip \ Parameters branch - the TcpWindowSize parameter (if not, create it manually). If you have an "super-ideal" Internet channel and want to increase the "sliding window" to 64 KB or more, then in the registry you need to create a dword key "Tcp1323Opts" with a value of "1" at the address HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ Tcpip \ Parameters.

The TTL (Time To Live) value indicates the period of time during which a certain packet (or, for example, a route), which the local PC knows about, will "live". Those. until this time expires, the computer will think that the packet it sent has not yet reached its destination, although it may have simply been discarded by the recipient, for example, due to a buffer overflow. This is where the possibility of increasing the speed is hidden. The point is that this value is high by default and must be decreased. On the other hand, if it is too small, then all packets will be considered lost and will be sent again and again. This obviously won't add speed to your channel. Therefore, the TTL value must be changed and the one you need, balancing between the two extremes. It is recommended to set the value of the DefaultTTL key equal to 128 in the HKEY_LOCAL_MACHINE \ System \ CurrentControlSet \ Services \ Tcpip \ Parameters key. By default it is assigned 255, which is clearly an overstated number. Windows 2000 / XP systems have the ability to selectively transfer damaged data. That is, if several packets are transmitted in a row and one of them does not reach the recipient, then the sender resends only the damaged packet, and not the entire series of packets. This, of course, also affects the speed, therefore, to enable this algorithm, create a dword key "SackOpts" with a value of "1" in the registry at the address HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ Tcpip \ Parameters.

There is one more parameter that is not used on NT systems, but many gamers are on 9x / Me, so it should be mentioned. NDI Cache (Network Device Interface) - Used by the operating system to store packet routing information. The default is 0. And you can change it in the registry branch HKEY_LOCAL_MACHINE \ System \ CurrentControlSet \ Services \ VxD \ NWLink \ Ndi \ param

s \ cachesize. It is necessary to change the Default key to the required value (16 is recommended). In addition to what has been described for manually optimizing the Internet connection, there are many programs that can automate this process. However, a huge number of them have now appeared, and you should not blindly trust everyone. Because they can "optimize" your Internet connection in such a way that the Network will easily disappear or will work at such a speed that it will satisfy only ICQ users, and even then not to the full. And web surfing or God forbid using ftp-archives will become impossible at all. Therefore, after analyzing a large number of programs, it is recommended to use Modem Booster first. The program is suitable for both "knowledgeable" users, and for those who do not have the slightest idea about the work of protocols, but also craves to improve the performance of the Network. You can download it, for example, from the site http://news.proext.com. It works in two modes - either the values of the key network parameters are manually set, or only one "Start" button is pressed and your Internet connection will be optimized automatically within 2-3 hours. It is suitable for almost all operating rooms

windows systems - from 98 to XP.

The Internet Tweak utility is more flexible. It also supports all Windows operating systems and has over 180 configurable parameters. It is possible to change the settings of popular browsers (Internet Explorer, Netscape Communicator), mail clients, as well as optimize the hidden options of the operating system. You can download it at http://www.magellass.com/files/inttweak.exe. The utility is shareware.

Named Moped.

“It will take place now

removal of the body of the deceased "(O. I. Bender)

Looking at the last epigraph, I wanted to advise the reader to throw away (the same as a gift) his good old winmodem and buy some Zyxel (Russian - "zuhel"). Moreover, as we understand, the more expensive Zyxel will be, the better and faster our connection with the Internet will be. Of course, looking into your wallet, where an honest gold piece (well, or something like that) has already been deposited on new number Upgrade Special, we immediately discard this seditious thought, and, rolling up our sleeves, are trying to squeeze the maximum out of our "peasant horse". First you need to make sure you have the latest driver installed. The fact is that almost all levels of the network model in winmodems are implemented in software, and the speed and some other communication parameters directly depend on the software.

Now let's get into the settings of your engineering marvel. Start> Settings> Control Panel> Phone and Modem Options, then select the Modems tab, where we see the installed modem. We go to Properties and here we see again the Modem tab. Set the Port speed parameter for the modem to 115200 (or higher, if your modem is of course capable of high speed). Here, not the connection speed of the modem and the provider is set, but the speed between the virtual port of the computer and the modem to which it is connected. That. this value should be the maximum, however, on older devices with low speeds (33600 and lower) setting this port speed may cause errors.

On the Diagnostics tab, you must turn off Logging. This will additionally load the processor and may result in additional downtime. In the Additional communication parameters tab, you need to

set the region to Russia, although some modems can work only if the country is set to USA. The Additional parameters ... button addresses you to the settings of the FIFO transmit-receive buffers (not to be confused with the "sliding window"). The size of these buffers must be maximized if we want to achieve more speed... The Change defaults ... button hides the settings shown in the figure below. It is recommended to set everything up as shown in the screenshot. At least as far as the Data Line Connection Parameters are concerned. It is important that compression is enabled, and hardware flow control that requires minimal system resources.

Leave the additional communication parameters unchanged. The function of manually tasking the modem initialization string can also be interesting. To do this, close the last custom window and return to the previous one. At the top we see a line with the name "Additional Initialization Commands". Now let's figure out what it is. Each modem has a protocol over which it operates, as well as the commands that it supports. These commands are used to control the modem using the operating system. And the speed of the device will depend on how it is initialized, and by and large and not only. As for the line itself, some general advice you can't give. For each modem, you need to select its own line, and in this case, you need to go for a walk on the Internet and look for documentation on the modem. By the way, if your device can be reflashed, then the release of the latest firmware versions should also be monitored. This is done using a special flashing program for a specific device model and, naturally, the binary code itself, written as a file. There is also a so-called. rollback firmware so that you can return everything to its previous state if problems arise. For many modems there are special configuration programs. For example, software for Rockwell-based modems can be found at http://www.rampitec.spb.ru/modem.htm.

Well, and the last thing I want to say about the modem settings, but rather, again, the application layer implementation, these are the protocols used. For the channel, you must use PPP, for the rest, the TCP / IP protocol stack. Compression of IP headers must be enabled, the DNS server (primary and backup) must be specified and WINS and NetBIOS disabled, if available in the settings. All this is done in the Start menu> Settings> Control Panel> Network connections, then Properties of the selected connection and the Networking tab.

What about Quake and Co.?

Now let's talk about the very games for which we quarrel with home, accept fasting (excluding chips, crackers, seeds and beer), ignore school / work and develop a passion for weapons, mass murder, profanity - in general, for everything beautiful.

By default, we consider Counter Strike (Half Life) and Quake to be the most popular 3D shooters of all times and peoples. It is for them that we will analyze the optimization of the Internet connection.

Due to the popularity of these games and the great interest of the progressive half of humanity in them, special programs begin to appear to optimize dial-up connections when playing with Internet colleagues. For CS, you can download AntiPing (a slightly incorrect name, AntiLag would be more correct) at http://money-home.narod.ru/antiping.rar. This is a configuration file that you need to copy to the directory where the game is installed and write the appropriate command in the console (the description in Russian is in the same archive). Detailed description console commands and new improvements of the latest CS patch can be found at http://counter-sport.by.ru/netgame/netgame.shtml. It also contains all the cheat codes and tips for optimizing the game on the Internet.

Quake 3 Arena has also released many productivity utilities (and not just Internet connections). The most popular program today is Q3A - Total Control v0.6. You can download it at http://planetquake.com/borderfield. During installation, the program itself finds the installed version of Quake 3 Arena. Next, run the utility and in the Tools> Dial-Up Optimizer menu we see the window shown in the screenshot.

As you can see, there are all the parameters described by us, and the value of which was supposed to be changed manually.

And finally ...

As you can see, there are many ways and approaches to optimize your Internet connection for playing over the network. This is the use of special programs that manually or automatically set the necessary values for the "connection" parameters, and alteration of the registry for your operating system and Internet channel using the regedit.exe utility, and changing only two or three main registry keys, which will give a tangible increase in the transfer speed data. In any case, the initiative should be rewarded. Therefore, do not be afraid to experiment, especially if the registry was exported on time. Well, as one famous film character used to say - "may the Force be with you"!

Optimizing your internet connection

How many times have you cursed your slow dial-up and started saving money for a dedicated line! Meanwhile, with skillful tuning, even the latest noname-modem can be as fast as expensive external models. It is recommended to optimize your Internet connection in several stages. We will start, of course, with the physical connection medium (FSS), but simply with the cabling.

The wiring from the modem to the dashboard simply has to be of high quality. Even small amounts of interference or unreasonable resistance can significantly reduce the speed of your Internet connection. The reason - the appearance of erroneous packages, the correction of which will require additional overhead.

It is recommended to use unshielded "twisted pair" - UTP of the 5th category as a cable subsystem. Shielded twisted-pair cable is usually not used for telephone wiring, but if you have no choice, remember to ground it. It should be recalled that any physical impact on the cable can lead to a change in its characteristics. Therefore, it is necessary to lay the line under the skirting board or in the boxes, avoiding strong bends.

The wiring in the apartment should be carried out in accordance with the figure. All telephones are connected to the line via a modem, and now the Internet has priority over "spoken devices". But this is not the most important thing. Our task is to eliminate any additional resistance that telephones create. All cable joints, the number of which should be minimal, must be soldered.

To avoid interference and pickup, the cable should be run at least 0.5 m to the power lines if they run parallel (crossing at right angles is permissible). It is also advisable to ground the system unit.

PROVIDER, REVIEW!

Now that we have the perfect cabling system, we can move on to choosing a provider. This is perhaps one of the key points in optimizing your internet connection. If you use a game server of your own provider, it doesn't matter what the width of its communication channel with the "outside world" is. Otherwise, this is perhaps the most critical parameter. Of course, it must be taken into account together with the number of users connecting to the provider and sharing the Internet bandwidth among themselves. Information about providers can be found, for example, on the website www.provider.net.ru.

Game traffic is very latency sensitive. Many people are familiar with this situation: you load some Quake 3 Arena, find like-minded people and ... you cannot hit the enemy from two meters, because while the information about your shot reaches the “enemy”, he has time to hide. In this regard, when choosing a provider, you need to pay attention to such a parameter as MTU (Maximum Transmission Unit) - the maximum data unit that is transmitted over the network.

A packet larger than the provider's MTU will be fragmented (as a rule, such fragmentation is allowed), which means that it will take longer to deliver useful information. Today's providers use switching equipment capable of independently adjusting the MTU size according to a given algorithm, which is adaptive. Therefore, it turns out that only the user can hard-code the MTU. Usually the user has dynamic MTU selection enabled by default, but we will set it manually.

When choosing a provider, you also need to pay attention to the status of the company, the number of corporate clients, availability of backup servers (mail, DNS and others), equipment and modem pool. It depends on how stable and fast your Internet requests will be processed.

INTERIOR OS

It's time to get into the holy of holies of the OS - the system registry - and configure the local Internet settings. There can be a huge number of parameters, especially if you take into account the tasks for which the application layer is implemented independently, and not by means of the OS. But we'll take a look at those that can have a significant impact on online gaming and connection speed.

QoS technology

In Windows XP, developers tried to take into account such an important area of modern networks as quality of service (QoS - Quality Of Service). This is because latency-sensitive traffic (such as voice or video) must take precedence over regular data. This is exactly what QoS technology does.

The developers of Windows XP began to reserve 20% of the bandwidth of the Internet channel for ensuring the proper quality of service (implementation of QoS RSVP - Resource Reservation Protocol). By the way, it should be said that QoS protocols do not work well on the Internet so far and they are unlikely to be used in the foreseeable future, at least in Runet.

Microsoft has published an article that states that QoS protocols work only with applications that were developed using the QoS API. We will not find such applications on a home computer, since they are mainly intended to support IP telephony or expensive distributed ERP systems (enterprise resource management systems), such as, for example, SAP R / 3. If you still do not want the RSVP QoS protocol to work on your PC, then you can set the reserved bandwidth to 0% or disable this service altogether.

We type gpedit.msc in the command line, then in Computer Configuration> Administrative Templates> Network> QoS Package Manager select “Limit Reserved Bandwidth”. Double-clicking will display a window in which you need to enable quality of service, and limit the bandwidth to 0%.

Next, make sure the QoS protocol is enabled: Network Neighborhood> Right Click> Properties> Internet Connection Properties> Network> QoS Packet Scheduler. If the protocol is not there, then it needs to be installed. After completing these operations, restart your computer. If you want to disable the service, then go to "Start"> "Settings"> "Control Panel"> "Administrative Tools"> "Services"> QoS RSVP and set the startup type to "Disabled" in the properties.

Let's go back to MTU first. The maximum packet in our switched networks, as a rule, is a data block of 1.5 kb. When using the internet for gaming, it is best to keep the MTU small. As already mentioned, the larger the packages, the longer it will take to deliver them, and gaming traffic cannot afford such a luxury.

Therefore, the MTU setting of 1.5 kb is excluded. On the other hand, if this parameter is too small, then a minimum of useful information will be transmitted, and a maximum of overhead data in the form of protocol headers and sync signals. This is also an extreme that should be avoided. The optimal and actually become the standard MTU value for the Internet (when the PPP protocol is running) is 576 bytes.

To set this value, run regedit.exe and look for the next registry key - HKEY_LOCAL_MACHINE \ System \ CurrentControlSet \ Services \ Tcpip \ Parameters \ Interfaces \ [Adapter ID]. There may be several adapters, and not all of them will be real. For each, create a MTU dword parameter and specify a value equal to 576 in decimal notation. There is also a parameter MSS - Maximum Segment Size. This is the size of the data segment, which, together with the protocol headers, is the MTU.

The size of the headers is fixed and is generally 40 bytes. Therefore, setting the MSS size is optional: with an MTU of 576 bytes, the MSS is 536 bytes. But if you still want to set the MSS value manually, create an MSS key in the same registry key.

There is an algorithm whereby two nodes can choose the MTU value themselves after exchanging their MSS values. This method is called Path Maximum Transmission Unit Discovery (PMTU Discovery). To enable it, create the EnablePMTUDiscovery key in the registry branch HKEY_LOCAL_MACHINE \ System \ CurrentControlSet \ Services \ Tcpip \ Parameters and assign it the value "1" (if this algorithm is disabled - "0").

The PMTU Discovery method has an extension that allows you to determine those routers that do not notify the host about packet loss if this occurs due to the impossibility of their fragmentation (these routers are considered dead-end and are not used in the future). The so-called Black Hole Detect algorithm is enabled by creating the EnablePMTUBHDetect key with the value "1" in the HKEY_LOCAL_MACHINE \ System \ CurrentControlSet \ Services \ Tcpip \ Parameters branch. It is advisable to disable both of the above algorithms, since their work can significantly slow down the process of messaging on the network.

The next important parameter is the so-called "sliding window". This is a kind of data buffer that is located at the receiving station and is filled by the source station with packets. Confirmation of their receipt is sent by the receiving station at any time, but no later than the data buffer overflows. Thus, packets sent by the source when the destination window is full will be dropped. This means that it is desirable to increase the window size for reliable lines, and decrease for bad ones.

The de facto standard for PPP (by which we work at the data link layer on the Internet) is a window size of 4.288 kb. If your lines of communication with the provider are reliable enough, then the specified size can be increased, but do not forget that the window size must be a multiple of the MSS (for example, 5.36 kb or 8.04 kb). This is to ensure that the window buffer is only filled with payload and is not reserved for smaller packets that it cannot accept.

We look in the registry branch HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ Tcpip \ Parameters - the TcpWindowSize parameter (if not, then create it manually). If you have an ideal Internet connection and want to increase the "sliding window" to 64 kb or more, then in the registry you need to create a dword key "Tcp1323Opts" with the value "1" at the address HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ Tcpip \ Parameters.

The TTL (Time To Live) value indicates the period of time during which a certain packet (or, for example, a route), which the local PC knows about, will "live". In other words, until this time expires, the computer will think that the packet it sent has not yet reached its destination (although it could have simply been discarded by the recipient, for example, due to a buffer overflow). This is where the possibility of increasing the speed is hidden. On the one hand, the default value is too high.

On the other hand, if it is too small, all packets will be considered lost and will be sent over and over again. This obviously won't add speed to your channel. Therefore, when choosing the TTL value, you need to balance between two extremes. It is recommended to set the value of the DefaultTTL key equal to 128 in the HKEY_LOCAL_MACHINE \ System \ CurrentControlSet \ Services \ Tcpip \ Parameters registry key (by default, it is assigned a clearly overestimated value - 255).

In Windows 2000 / XP systems there is a possibility of selective transmission of damaged data: if several packets are transmitted in a row and one of them does not reach the recipient, then the sender resends only the damaged packet, and not the entire series of packets. This, of course, also affects the speed, therefore, to enable this algorithm, create a dword key "SackOpts" with the value "1" in the registry at the address HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ Tcpip \ Parameters.

There is one more parameter that is not used in NT systems, but still deserves a mention, since many gamers are "sitting" on 9x / Me. The NDI Cache (Network Device Interface) is used by the operating system to store packet routing information. By default, its value is 0. If necessary, in the HKEY_LOCAL_MACHINE \ System \ CurrentControlSet \ Services \ VxD \ NWLink \ Ndi \ params \ cachesize registry key, you can assign the desired value to the Default key (16 is recommended).

Automatic optimization

You can optimize your Internet connection not only manually, but also automatically, using special programs. A huge number of them have now appeared, but you should not blindly trust everyone. Some of them can so damage your Internet connection that the Network can easily disappear or work at a speed that is not able to satisfy even ICQ users.

We advise you to pay attention to the Modem Booster program. It is suitable for both knowledgeable users and those who do not have the slightest idea about the operation of protocols, but still yearn to improve the performance of the Network. You can download it, for example, from news.proext.com. It works in two modes - either the values of the key network parameters are manually set, or only one "Start" button is pressed and your Internet connection is optimized automatically within 2-3 hours. It suits almost everyone operating systems Windows - 98 to XP.

The Internet Tweak utility is more flexible. It also supports all Windows operating systems and has over 180 configurable parameters. The user gets the opportunity to change the settings of popular browsers (Internet Explorer, Netscape Communicator), mail clients, as well as optimize the hidden OS options. You can download this shareware utility at www.magellass.com/files/inttweak.exe.

EDUCATION OF A MODEM

Now let's get down to the good old "winmodem" and try to squeeze the maximum speed out of it.

First you need to make sure that you have the latest driver installed. The fact is that almost all levels of the network model in "winmodems" are implemented in software, and the speed and some other communication parameters directly depend on the software.

We get into the settings of this miracle of engineering: "Start"> "Settings"> "Control Panel"> "Phone and Modem"> "Modems". We see the installed modem, go to "Properties" and here again we see the "Modem" tab. The parameter "Port speed for the modem" is set to 115200 bps (or higher - if, of course, your modem is capable of this).

Here you set not the speed of the connection between the modem and the provider, but the speed of data exchange between the virtual port of the computer and the modem to which it is connected, and its value should be maximum. However, it should be noted that on older devices with limited capabilities (33,600 bps and below) setting this port speed may cause errors.

I love simple "one-click" programs for a computer, especially if they are in Russian, free and do everything that users expect from them.

Today I want to talk about a similar program for Internet optimization.

Auslogics Internet Optimizer will automatically check your system and browser settings of the Internet connection and optimize them with one click of the computer mouse (there is also a manual mode in the program for advanced users).

This program was once independent, and now it is included in the Auslogics BoostSpeed optimization package. This is a great set of programs for speeding up your computer, but a little paid and a lot.

Although Auslogics Internet Optimizer is included in the free trial version of Auslogics BoostSpeed, I still suggest that you temporarily install a clean version of Internet Optimizer, improve your network settings with one click, and then uninstall it.

So you can do without unnecessary programs ( running services) on your computer and get faster loading sites.

Attention! Auslogics Internet Optimizer will not expand your Internet channel given by the provider, but will change the network settings for faster display of sites, which will achieve Internet optimization.

To many, the explanation above will seem complicated, therefore the best way understand it - install the program and make sure the Internet accelerates in practice.
