Why can't you open the forum of Gaoyou Wenyoutai? I can't diagnose the connection problem of this webpage.

1. Friends with more than one computer can change one computer. Don't install any proxy server software or any firewall on the replaced computer, just install a network card to directly connect with ADSLMODEM. After installing ADSL dialing software correctly. See if you can browse normally. If so, the fault is caused by the client's computer. If not, you need to check whether the modem and line are normal.

2. Friends with only one computer can stop running all proxy server software, such as WINGATE, SYGATE and INTERNET access (ICS) of WINDOWS, and log in directly to see if the fault can be eliminated. If the fault is eliminated after stopping running the proxy server software, it must be a problem with the proxy service software.

3. Check the browser settings, especially IE. For example, the most common failure to browse the web is to select "automatic detection settings" in IE. Remember, never select this option. If it is IE5X version, click Tools-Intranet Options-Connection-LAN Settings to see this option. If this option is ticked in front, you must cancel it. The fault can be solved after cancellation.

4. Check whether the attribute settings of TCP/IP protocol, especially DNS server settings are correct. In particular, the location of setting DNS varies with different dial-up software, some are set in the connection icon attribute of dial-up network, some are set in the control panel network, and some are set in the connection profile attribute of dial-up software (such as ENTERNET300). These three places must be set correctly.

5. Friends who use WINDOWS can prepare ADSL dial-up software and WINDOWS system CD-ROM, then delete the dial-up software first, then delete all TCP/IP protocols in the control panel/network, restart the computer, add TCP/IP protocols again, turn on the modem power, and reinstall the dial-up software. After testing, if the settings are correct, most of them can solve the problem that after reinstalling the dial-up software and TCP/IP, they can dial-up but cannot browse the web.

6. Replace a browser software such as Netscape's Netscape browser browsing test.

7. If you have two network cards installed in the computer directly connected to the ADSLMODEM, please try to pick up the network card connected to the LAN first, leaving only the network card connected to the ADSLMODEM. Then see if the fault is eliminated. If troubleshooting, you should check the configuration of network and system resources. Especially to see if there is any conflict between the network card and other devices (WINDOWS users can check whether the devices are normal in the control panel/system/device management).

8. Your network card has BOOTROM chip boot function enabled, and the network card has PXE boot chip. It can be solved as follows:

① If the network card is integrated on the motherboard, or the online boot program is written into the BIOS, the boot sequence of the system can be modified from the BIOS settings, such as setting the hard disk to boot first, or prohibiting the network card from booting the system from the BIOS.

(2) If there is no integrated network card, you can unplug the boot chip on the network card or set the program with the network card, and the BootROM boot function of the network card can also be turned off. Then, when "press shift-f 10 to configure ..." appears, immediately press the key combination of "Shift+F 10" to enter the menu, and set Bootorderrom to be disabled from the fourth line.
