The network link and data packet display are normal, but the network speed is so slow that it is basically impossible to open the web page. Sometimes it is slightly better. How to break it?

1. Problems with network settings

This reason often occurs when you need to manually specify the IP, gateway, DNS server networking method, or use a proxy server to access the Internet. Double-check your computer's network settings.

2. DNS server problems

When IE cannot browse the web page, you can first try to access it using the IP address. If it can be accessed, it should be a DNS problem, causing DNS problems. The problem may be an error in obtaining DNS when connecting to the Internet or a problem with the DNS server itself. In this case, you can manually specify the DNS service (the address can be the DNS server address provided by your local ISP, or you can use the DNS server address that can be used normally elsewhere.) Proceed in the properties of the network, (Control Panel - Network and Dial-up Connections - Local Area Connection - Right-click Properties - TCP/IP Protocol - Properties - Use the following DNS server address). Different ISPs have different DNS addresses. Sometimes it is a problem with the router or network card that cannot connect to the ISP's DNS service. In this case, you can turn the router off for a while and then on again, or reset the router.

Another possibility is that there is a problem with the local DNS cache. In order to improve website access speed, the system will automatically store the website that has been visited and obtained the IP address into the local DNS cache. Once the website is accessed again, the website will be retrieved directly from the local DNS cache without going through the DNS server. IP address for access. Therefore, if there is a problem with the local DNS cache, the website will be inaccessible. You can execute ipconfig /flushdns in "Run" to rebuild the local DNS cache.

3. Problems with the IE browser itself

When the IE browser itself fails, it will naturally affect browsing; or if IE is maliciously modified and damaged, it will also cause the inability to browse the web. . At this time, you can try to use "Huangshan IE Repair Expert" to repair it (it is recommended to repair it in safe mode), or reinstall IE (if you encounter problems that cannot be reinstalled when reinstalling IE, please refer to: Appendix 1 to solve the problem of being unable to reinstall IE)

4. Network firewall problems

If the network firewall setting is improper, such as the security level is too high, IE is accidentally put into the blocked access list, the wrong firewall policy, etc., you can try to check policy, lower the firewall security level or turn it off directly to see if it returns to normal.

5. Problems with network protocols and network card drivers

If IE cannot browse, it may be caused by damage to the network protocol (especially the TCP/IP protocol) or network card driver. You can try to reset the network card. Drivers and network protocols.

6. Problems with the HOSTS file

If the HOSTS file is modified, it will also cause abnormal browsing. The solution is of course to clear the contents of the HOSTS file.

7. System file problems

When the system files related to IE are replaced or damaged, it will affect the normal use of IE. In this case, you can use the SFC command to repair it. In WIN98 system, you can execute SFC in "Run" and then scan; in WIN2000/XP/2003, you can execute sfc /scannow in "Run" to try to repair it.

When only IE cannot browse the web page, but QQ can access it, it is often caused by damage or loss of files such as winsock.dll, wsock32.dll or wsock.vxd (VXD only exists under WIN9X system). , Winsock is an important part of the TCP/IP protocol, and the TCP/IP protocol generally needs to be reinstalled. However, XP began to integrate the TCP/IP protocol, so it cannot be simply uninstalled and reinstalled like 98. You can use the netsh command to reset the TCP/IP protocol to restore it to the state when the operating system was first installed.

The specific operations are as follows:

Click "Start Run", enter the "CMD" command in the run dialog box, the command prompt window will pop up, then enter the "netsh int ip reset c:\resetlog.txt" command Just press Enter. The "resetlog.txt" file is a log file used to record the results of command execution. This parameter option must be specified. The full path of the log file specified here is "c:\resetlog.txt". The result of executing this command is the same as removing and reinstalling the TCP/IP protocol.

Tips: The netsh command is a command line-based scripting tool. You can use this command to configure and monitor Windows systems. In addition, it also provides an interactive network shell interface. The usage format of the netsh command Please refer to the help file (enter "netsh/?" in the command prompt window).

The second solution is to repair the above files. WIN9X uses SFC to re-extract the above files. WIN2000/XP/2003 uses the sfc /scannow command to repair the files. When sfc /scannow cannot be used to repair the files, you can try WinSockFix, a repair tool released online specifically for this problem, can be searched and downloaded online.

8. The problem of real-time monitoring of anti-virus software

This is not very common, but sometimes it is related to real-time monitoring, because now the real-time monitoring of anti-virus software has added the content of web pages. monitor. To give an example: KV2005 will cause IE to be unable to browse the web on certain machines (many friends have encountered this). The specific manifestation is that as long as web monitoring is turned on, IE will be unable to browse after about 20 minutes of surfing the Internet after turning on the computer. If the webpage monitoring of KV2005 is turned off at this time, everything will return to normal; even a complete reinstallation of KV2005 cannot solve the problem. Although this problem does not occur on every machine where KV2005 is installed, after all, the system of each machine is different and the installation procedures are also different. But if IE cannot browse the web, you should also check the anti-virus software.

9. Problems with the Application Management service

If you can only access QQ but cannot open web pages, it will be fine after restarting. However, even after restarting, after opening 7 to 8 web pages, I can no longer open web pages and can only access QQ. Sometimes China Telecom will ask you to disable the Application Management service and that will solve the problem. The specific reason is unknown.

10. Caused by virus infection

This situation often occurs when you open IE. In the lower left box of the IE interface, there is a prompt: The web page is opening, but it has not responded for a long time. Check the process in the task manager (enter the method, put the mouse on the taskbar, right-click - Task Manager - Process) and see how the CPU usage is. If it is 100%, you can be sure that it is infected with a virus. At this time, you are simply suffering if you want to run other programs. This requires checking which process is greedily occupying CPU resources. After finding it, it is best to record the name and click End. If it cannot be ended, you need to boot into safe mode to delete the thing and enter the registry (Method: Start-Run, enter regedit) before registering. In the table dialog box, click Edit-Search, enter the program name, and after finding it, click the right mouse button to delete it, and then search several times, which can often completely delete it.

There are many viruses, and when anti-virus software is unable to do anything, the only way is to delete them manually.

11. Unable to open secondary links

There is another phenomenon that requires special attention: the homepage of the website can be opened, but the secondary links cannot be opened. If this is the case, how to deal with it? The method is to re-register the following DLL file:

Enter in Start-Run:

regsvr32 Shdocvw.dll

regsvr32 Shell32.dll (note this command , no need to lose yet)

regsvr32 Oleaut32.dll

regsvr32 Actxprxy.dll

regsvr32 Mshtml.dll

regsvr32 Urlmon.dll < /p>

regsvr32 Msjava.dll

regsvr32 Browseui.dll

Note: Press Enter after each entry. You don’t need to enter the second command yet. Restart Windows after entering these commands. If you find that it is invalid, enter it again, this time enter the second command.
