How to speed up the Internet

1. The most important problem for a friend who uses broadband Internet access is network speed. we use various methods to speed up the ADSL modem (the device used for Internet bandwidth. such as modifying the registry, the effect is often unsatisfactory. here. I recommend an effective acceleration method.
The ADSL modem device is usually connected to the computer through the NIC. First, ensure that your computer has more than MB. If your memory is too small, this method will affect the system operation.
Click Start> Run. In the run dialog box, enter the msgd32.exe command. press enter to bring up the "System Information" window. expand "hardware resources> IRQ" in sequence, and then find the IRQ resources used by the network adapter in the resource box on the right. Take the author's computer as an example, it uses irq17. then it begins to modify "system. INI file. click Start> Run and enter sysedit in the dialog box. EXE command, press enter to bring up the "System Configuration Editor" window, switch to system. in the INI file, find the section "[locale ENH]" and add "irq17 = 4096" to the section below. "irq17" is the IRQ resource used by the author's computer NIC (the value varies with machines ). finally, save the file and restart the system. in this way, the Internet access speed of the ADSL modem can be improved.
This test was conducted in a 2 m broadband environment, and the download speed has been improved by dozens of kb/s.
2 start ---- run ----- Regedit (enter the Registry) ----- HKEY_LOCAL_MACHINE/system/CurrentControlSet/services/tcp | IP ultttl under the IP/Parameters key changes its value from 40 to 80 (hexadecimal). If 64 is changed to 128 (decimal)
Then exit the Registry-restart the computer. When you go to the webpage, you will see an improvement in the network speed.
3. enter gpedit in "Start> Run. MSC opens the Group Policy Editor. find "Computer Configuration> Management Board> network> QoS packet scheduler" and select "restriction on the right to retain the broadband attribute dialog box, select "enable" and change the original "20" to "0", so that the original reserved part is released.
4 {computer skills} accelerate broadband Internet access

If you are using broadband access, you can set the appropriate tcpwindow value in the Registry to speed up the Internet access.
Open Registry Editor and find
"HKEY_LOCAL_MACHINE \ SYSTEM \ currencontrolset \ Services \ Tcpip \ Parameters" sub-key,
In the key-value area on the right, locate or create a DWORD key-value item named "globalmaxtcp windowsize", set the data value to "256960" (decimal), and close the registry editor, restart your computer.
5. Speed up Internet access



There are several ways to change the Internet speed:
HKEY_LOCAL_MACHINE/system/CurrentControlSet/services/VxD/mstcp. In the window on the right, change "defaultrcvwindow" to "6400" and change "defaultttl" to "128 ". HKEY_LOCAL_MACHINE/system/CurrentControlSet/services/class/nettrans, create the string value "maxmtu" and "maxmss" in the right window, and set "maxmtu" to "576 ", set "maxmss" to "536 ".


6. How to improve the web browsing speed
The setting method is as follows:
Open IE (close other IE pages)
Tool-Internet option-General-settings-used disk space-the default value is 93 MB, and the size is changed to 1 MB. Feel the speed!
The original intention of using disk cache in Windows is to speed up web page browsing, but this is not the case in the use process. After changing this to 1 m, the browsing speed is fast, however, browsing some websites is slow.
7. Check the current speed
Before optimization, we need to check the existing network speed to find the best network optimization solution for the local computer. Otherwise, the network may be abnormal.
When checking the network speed, you can use "ping" to learn about the relevant network parameters, you can also test the download speed by downloading a relatively large file from a relatively stable website. Generally, you can use related software to check the network speed, such as "TCP optimizer.
Optimize Registry
The most direct way to optimize the network speed is to change the registry. You can refer to some materials to modify the corresponding key value of the registry, but note:
This operation may cause system instability or even crash. Please back up the Registry in advance for recovery in case of a fault.
The modifiable key values are as follows:
1. maxmt: Modify the maximum transmission unit.
2. defaultrcvwindow and defaultttl set the size value of the transmission unit buffer and the TCP/IP Group Life.
3. Set DNS query priority to speed up web page browsing.
4. Increase the RAM used by TCP/IP: Increase the buffer used by TCP/IP to increase the data rate.

Several methods to improve the web browsing speed

2006-04-23 09:19:18

Large, medium, and small
The browsing speed is usually high when you first access the Internet. However, as the Internet goes on, the speed will get slower and slower, and sometimes it is even unbearable. The most fundamental and effective way to increase the browsing speed is to upgrade the PC. The faster the CPU and memory are, the faster the browsing speed is. However, under the existing conditions, several common methods can also increase the speed.
I. Operating System settings
Increase the XP speed, and the Web browsing speed can naturally be accelerated.
(1) Expand the virtual memory
When there are many browsing windows or many running programs, the system often prompts that the virtual memory is insufficient, and increasing the virtual memory can also increase the speed.
Right-click "my computer"-properties-advanced-performance-advanced-virtual memory, and try to set high virtual memory. When downloading programs or files at the same time, try not to go down to drive C to keep drive C large.
(2) Set visual effects as appropriate
Set as few visual effects as possible.
Right-click "my computer"-properties-advanced-performance-visual effects, generally, you only need to set "display window content when dragging", "use visual style on Windows and buttons", and "use common style for Folders.
(3) Stop unnecessary background services
Right-click "my computer"-"management"-"services" and "Applications"-"services". For background services (such as fax and services that do not require remote assistance) can be disabled, stopped, or set to manual.
(4) set the appropriate "start" menu
Right-click "Taskbar"> "properties"> "Start Menu"> "Custom"> "advanced". You only need to set "enable drag-and-drop", "Search", and "run". Other settings can be set as needed, this improves the boot speed and XP speed.
Ii. iesettings
(1) set a large temporary Interent folder
IE saves browsed web pages in the temporary Interent folder and extracts them directly from the Temporary Folder during the next browsing. This is faster, so as long as you permit, set the temporary Interent folder to the maximum.
In IE, click the tool menu-Interent option-General to set the temporary Interent folder (Be sure not to set it to disk C ).
(2) set appropriate "advanced" Options
In IE, click the tool menu-Interent option-advanced. If you want to avoid video or animation, you can increase the speed as needed.
(3) Manage Add-ons
When browsing web pages or downloading programs, some functions are often loaded in IE to make browsing slow. Therefore, check the add-ons and manage them.
In IE, click tool menu-Manage Add-on to disable loaded projects.
Iii. Network acceleration Software
You can use some secure network acceleration software to speed up browsing.
Iv. Virus and plug-in cleanup
Sometimes virus intrusion slows ie down. You need to upgrade anti-virus software to scan and kill viruses. You can also download specialized tools (such as hijackthis) to scan and kill viruses. If necessary, you can directly delete virus programs in Windows security mode.
9 The easiest way to increase the speed of Web browsing

In the Start Menu, click the "run" command to open the "run" dialog box, type regedit, and press the "OK" button to open the Registry Editor,
Operation subkey [HKEY_CURRENT_USER/software/Microsoft/Windows/CurrentVersion/internetsettings]
Find the key value on the right bar of the Registry Editor:
Maxconnectionsperserver
(DWORD Value) If this key value does not exist, create this DWORD Value (right-click to create this DWORD Value)

Key value (description) 10 (set the maximum number of connections for Synchronous download to 10 lines)
You can modify the key value according to your own needs, such as 30, 40, 50 ,...... And so on. Try it out. Does it significantly improve the browsing speed of the web page (haha)? This method also greatly increases the speed of using IE to download files.

Improve web browsing speed
Many people say that the Internet access is too slow. Yes, according to the current Chinese facilities, the Internet access is a little slow, but some basic settings can improve your Internet access speed a lot. Below are a few simple methods.
1. Temporary Folder settings
Browsing Web pages is highly repetitive. Temporary folders are determined by this. When you repeatedly browse the same web page, the computer will call the web pages in the Temporary Folder, it won't pass through the server, just like watching what's on your hard disk. Right-click the IE icon on the desktop, and a Properties window appears. In the general options, there is a Temporary Folder setting, where you can adjust the location and size of the Temporary Folder. You can also delete the content.
2. Multimedia settings
This is still an attribute window. One of the advanced options is multimedia settings. Generally, you only need to tick the displayed image and the optimized image jitter. Currently, all webpages are text and images, choosing to display images is enough for most websites. Optimizing image jitter is for your eyes. What? If you don't even read the graph, it's easy. You can choose none of the seven options.
3. Proxy Server
The proxy server stands for proxy Cerver. Its function is to obtain network information from the proxy network user. It is a transfer station for network information. With it, the browser does not directly go to the Web server to retrieve the webpage, but sends a request to the proxy server. The proxy server will retrieve the information required by the browser and send it to your browser. In addition, most proxy servers have the buffer function, which is like a large cache, which has a large storage space and constantly stores new acquired data in its local memory, if the data requested by the browser already exists and is up-to-date on its local memory, it will not retrieve data from the Web server again, directly transfer the data in the memory to the user's browser, which can significantly improve the browsing speed and efficiency.
Take IE 5.0 as an example: in the menu bar "Tools"-> drop-down menu "Internet Options"-> tab "connection"-> select the connection you are currently using in "dial-up Settings, click "Settings"-> in the middle of the "Proxy Server" column, select "use proxy server"-> enter HTTP Proxy server in the "Address" and "Port" columns-> OK-> OK. For LAN users, click "LAN Settings" under the "connection" tab to set the proxy. You can use the search engine to find out how the proxy server address is obtained. Do not forget to choose not to use the proxy server for the local address.
The above is to improve the web browsing speed by optimizing the browser, you can also use the software to optimize the network to achieve better results, software in this area includes "fast cat whip", "nettweak", and "Internet Optimizer", which will not be detailed here.

11. Modify the Windows XP registry to speed up Internet access

Windows XP limits the bandwidth connection speed. Does it mean that we can modify the operating system to get a faster Internet access speed?
A: Now broadband networks are gradually becoming more and more widely used. However, some broadband network users still have low Webpage Browsing speed, uploading speed, and downloading speed. In fact, in Windows 2000 or XP, by modifying the registry, We can greatly improve the speed of the broadband network and truly enjoy the fun of surfing the Internet.
Run regedit to open registry manager. Then, locate HKEY_LOCAL_MACHINE/system/CurrentControlSet/services/TCPIP/parameters in the following path.
Right-click the blank area on the right of the parameters subkey, select "new"> "DWORD Value", and name it "defaultttl". Then, right-click and select "modify". In the displayed window, change the value to "80" (hexadecimal) or 128 (decimal ).
Create the following "DWORD Value" in sequence and modify its value (if there are two values, the former is hexadecimal, and the latter is decimal ):
"Enablepmtubhdetect" = "0"
"Enablepmtudiscovery" = "1"
"Globalmaxtcpwindowsize" = "7fff" or "32767"
"Tcpmaxdupacks" = "2"
"Sackopts" = "1" string 4
"Tcp1323opts" = "1"
"Tcpwindowsize" = "7fff" or "32767" (93440 or 186880 or 372300, depending on network conditions)
Then save our changes and restart the computer to enjoy the pleasure of higher network speeds.

12 increase internet access speed



For most netizens, Internet access fees are still a huge expense. Therefore, how to improve Internet access efficiency and reduce Internet access costs is of special concern to many netizens. I have some experiences on surfing the internet for a long time. I will list them below and share them with you. First, you should select an ISP to learn about your telephone line. The connection speed, network bandwidth, and stability provided by the ISP (Internet Service Provider) are the most important factors affecting the Internet access speed. A friend complained that his 56 K "cat" was always unable to reach the 56 K connection speed. In fact, this is because of his isp. Many 163 of telecom ISPs support the 56 K connection speed, however, most ISPs of 169 support only 33.6 K. Therefore, you must select an ISP. Generally, the ISP directly under China Telecom is the fastest. Second, the quality of telephone lines is also very important. A telephone line with a noisy call may not provide high-speed connections. You may not be able to choose the quality of the telephone line, but once the quality of the line is found to be poor, you should negotiate with the Telecommunications Department in a timely manner. In addition, try to avoid using extensions to access the Internet. The second option is advanced access. The most ideal of course is ADSL and cable access, but it is not yet popular. The reality is that the use of ISDN access can greatly improve the speed of the Internet, but the cost is generally twice the speed of dial-up Internet access, you can choose either of them. The third option is to select a suitable time for accessing the Internet. The current peak hours are between and on the working day ~ ~ So try to avoid surfing the Internet during busy hours. The best time to access the Internet in the fastest time period. The fastest time period is ~ And most of the holidays. Fourth, the higher the configuration of your machine and software system, the smoother the Internet access. Among them, modem speed, memory size, CPU clock speed, hard disk speed, and so on are the main reasons that affect the Internet access speed. We recommend that you upgrade your machine configuration as much as possible: the modem should be 56 K, the memory is 32 m, the CPU clock speed is 350, and the latest hard disk is used. You will find that, the cost of upgrading your machine will soon be compensated for the cost saved on the Internet. The software mainly involves the operating system, browser, FTP, etc. Generally, the new version is always faster and more powerful, and the operating system and browser should be upgraded to the latest version as much as possible. Fifth, the system settings can significantly improve the speed of surfing the Internet through some appropriate settings of the system on the premise of software and hardware configuration, ISP and so on. 1. Select "modem" in "Control Panel" for "modem configuration", click "properties" under "General", and select the maximum value "115200" in "shortest speed" settings ". Click Connect, and do not select pending dialing tone before dialing ". Click "Port Settings", select "use FIFO buffer", and set "Accept buffer" and "Transport buffer" to the highest. In the "advanced" option, select "hardware (RTS/CTS)" in "use flow control", and do not select "request connection" in "use error control ". In the additional settings column, type S11 = 50 to set the audio duration and interval to the minimum value (50 ms). 2. the COM port configuration modem should be connected to the com2 of the host, because the com2 is higher than the COM1 interrupt priority, which can ensure that the modem interrupt request is preferentially responded. In addition, you also need to set the com2 port. Select "Control Panel", double-click "system", click "Device Manager", expand "port (COM & LPT)", and double-click "communication port" to connect to the modem ", click "Port Settings", select "115200" in the "baud rate" column, select "8" in the "Data bit" column, and select "NONE" in the "parity" column ", select "1" in the "stop position" column, and select "hardware" in the "Traffic Control" column ". Edit the "win. ini" file and change "com2 = 9600, N, 8, 1, x (default)" to "com2 = 921600, N, 8, 1, P ". 3. for network configuration, right-click "Network Neighbor", click "properties", and select "Microsoft network user" from "main network logon ", delete unnecessary protocols in "The following network components have been installed", such as "netbeui" and "IPX/SPX". It is best to keep only the "TCP/IP" protocol. 4. in the dial-up network configuration, open "Dial-Up Network" and click "properties". Under the "General" project, "Use area code and dialing property" is not selected ", in "server type", "advanced options" are not selected. Pay special attention to removing the "Logon network" option in "allowed network protocols ", select "TCP/IP" only. Click "TCP/IP Settings", select the "servers with assigned IP addresses" option, and select the "server address with specified name" option, enter the server address provided by your ISP in "Master DNS" and "secondary DNS. 5. system Optimization Settings Using the "fast cat whip" software this software can be used for maxmtu, defaultrcvwindow, defaultttl, namesrvquerytimeout, maxsocket and NDI, namecache and pathcache, pmtudiscovery and volume, comport buffer, the modem initialization string and TCP/IP entry are automatically optimized. Sixth, browser settings and usage tips web surfing is the most exposed to browser software. To improve the speed, you can make some settings for the browser: for example, disable automatic image download, disable Java, and set both the memory cache and disk cache to a large value. Among them, the "verity documents" option is single, you can use "reload" to update the page in the disk cache. Cancel the launch page of the browser software, so that the browser will not automatically load any page at startup, which is conducive to improving the speed. Sort out your bookmarks frequently. Taking advantage of the multi-task feature of windwos and opening multiple browsing windows at the same time is a good habit of Improving the Internet efficiency. Generally, it can be opened three to three times at the same time based on the machine level ~ 10 windows are recommended. You can also send and receive emails and perform FTP operations while browsing the Web page. You can also use some browsing accelerator software, modem, and network optimization software, and Use offline browsing software to greatly improve the Internet access efficiency. Try to use multiple threads when downloading files. When you know the HTTP and FTP addresses of the downloaded files, selecting the FTP method for downloading can also greatly improve the download efficiency.
13. Increase the Internet access speed of XP

Copy the following content to the new registry key, and double-click it to run it. restart the computer to achieve the download speed of more than kb without the need to download tools, it is also relatively stable. You can use IE to download multiple files from one website at the same time.
How to create a registry key: Open notepad, copy the following content (excluding ======) to notepad, and select "all files" as the storage class. Then, the file name must start. reg is a suffix. After saving the file, the generated registry key is generated. You can double-click the generated key. reg file to modify the registry.

14. How can I speed up Web browsing? I am from China Netcom.

Best Answer
Hardware considerations:
1. The network cable length should not be too long. The network cable must be 568a or 568b.
2. If you use ADSL to access the Internet, change the telephone line before the Shard to a network cable. The Shard connector must be connected properly and pay attention to the heat dissipation of ADSL.
System Optimization:
1. Internet Options-security-Custom Level-Disable all the script options (we recommend that you retain the script and paste it)
2. Internet Options-advanced-multimedia-choose not to play sound, animation, and video
3. Internet Options-advanced-browse-check to disable script debugging

16 In our common Windows XP operating system, the default MTU value is 1500, which is a standard Ethernet value and is not suitable for broadband networks, generally, when the MTU of ADSL bandwidth is between 1450 and 1492, the MTU mismatch between the system and ISP will directly lead to data subcontracting and group packets during network transmission, it wastes valuable transmission time and seriously affects the efficiency of broadband. This requires that the MTU value of the local machine be set to the same as the MTU value used by the ISP before you can quickly browse the Web page and download data. However, the MTU values used by ISPs in each region are different, and the ISP may occasionally change the local MTU size, which makes it inconvenient to set the local MTU, how can we know what the isp mtu is? In fact, the most commonly used ping command can help us easily test the MTU size of the local ISP. If you are interested, please take a look at it with the author.
Test ideas
On the wide-area network, data packets exceeding ISP requirements cannot be transmitted, and the operating system will automatically subcontract the data that does not meet the requirements based on the MTU value of the Local Machine before transmission, therefore, we can send a fixed-length packet to a host on the Internet, and do not allow the operating system to change its size to check whether the packet can be transmitted normally, if the data packet is smaller than or equal to the ISP's MTU value, the transmission will be normal. If the sent data packet is greater than the ISP's MTU value, the transmission will fail, in this way, we can get the MTU size of the ISP end by continuously sending data packets of different sizes, and this data plus 28 bytes of packet header information is the final MTU value we need.
3. Observe the feedback results and determine the isp mtu value (pay attention to the marked yellow box in the figure)
1) The first time the test package is sent, the package length is 1450
1. If the packet size is too large and requires subcontracting, the packet size should be reduced if the value (1450) is greater than the MTU of the ISP.

2) The second test packet sent, with a length of 1440
2. The data packet size is reduced to 1440, prompting that the data packet is too large. Therefore, the system determines that the value (1440) is greater than the MTU of the ISP and should continue to decrease

3) Send the test package for the third time. The package length is 1430.
3. The packet size is reduced to 1430, prompting that the packet can be transmitted normally. Therefore, it is determined that the MTU value of the ISP is Between 1440 and ~ Between 1430

4) Send the test package for the fourth time. The package length is 1435.
4. The data packet size is increased to 1435, prompting that the data packet can still be transmitted normally. Therefore, it is determined that the MTU value is Between 1440 and ~ Between 1435

5) Send the test package for the fifth time. The package length is 1438.
5. The data packet size is increased to 1438, prompting normal transmission. Therefore, the MTU value is determined to be Between 1440 and ~ Between 1438
6) The sixth packet sent, with a length of 1439
6. When the packet size is increased to 1439, the system prompts that the data packet cannot be transmitted because it is too large. Therefore, the MTU value of the ISP is determined to be 1438.

4. Calculate the MTU value of the Local Computer
The above MTU value cannot be directly used for local settings, and 28 (Baotou size) should be added on this basis. Therefore, the final MTU value is 1466
5. Modify the MTU value of the Local Machine
You can modify the default MTU value of the local machine through the registry, but the more intuitive and secure method is to use some system optimization software, such as "Super Rabbit" or "Windows optimization master, this example uses "Super Rabbit v6.25" for demonstration. 7. Enter the screen for setting the network tag by magic. First, select the check box before "use the maximum transmission unit", and then enter the calculated MTU value (1466) in the data column) then click OK and restart the computer.

Summary
As mentioned above, the whole process may seem cumbersome, but the idea is very simple and the effect is good. After the MTU value is set on my computer, the speed of the browser to open the page is improved by 15% compared with that before the setting, and the effect is quite obvious. ㄖ ppoe's dial-up ADSL, this method is not applicable to optical fiber access or broadband network connected by ISDN
