My computer is often disconnected in hot weather, and I have to restart it before I can connect it.

1. The network lines are in poor contact, most of which are loose plugs and some are disconnected. 2. There are problems with the quality of network hardware, such as double glue line, crystal head, separator, cat, router and network card. Excellent quality of cat router and network card is important. 3. Pay attention to the heat dissipation of separators, cats and routers. 4. If the integrated network card is unstable, you can change an independent network card and update the network card driver. My Computer-Properties-Hardware-Device Manager-Right-click the network card under the adapter-Properties-Advanced-Select mode on the left and 1 Full Mode on the right-OK. 5, XP had better use the system's own dial-up program, 98 Internet dial-up tool software, you can choose RasPPPoE or WinPoET, note that only one dial-up tool software can be installed in a computer, otherwise it will cause conflicts. 6. Set the TCP/IP protocol and set a fixed IP address for your computer. 7. The user is too far away from the computer room, the line loss and interference are large, the network use is limited or the peak broadband is cut off. 8. The power supply voltage is unstable, or the Internet is not normal due to poisoning.
