4 Scene reproduction

4.1 Occurs once

insert image description here
When I went to eat, the computer was still hanging on the ladder . After eating, the computer screen shut down, and then this appeared. There was a WiFi icon at the beginning, but I couldn’t connect to the network. After 2.3 operations, it returned to normal. After 2, the icon It also disappeared, but after 3, the computer restarted and it became better

It is seriously suspected that the ladder occupies or affects the connection drive port of the WLAN. The specific reason is not yet known.

The main application is clash, connected to the node in Singapore

4.2 appears twice

Just now, I was hanging the ladder and watching YouTube, and suddenly the network was gone again, and I couldn’t connect. Then perform the operation in 2, click restart, and it will return to normal again! Finally figured out why my WiFi connection was not working. (2023.08.08)

The details are why. When I have time to find out, it is estimated that it is a problem of the occupation between the ladder and the network adapter. I don’t know the details.

4.3 Causes of clashes

Now I can figure out why I can’t access the Internet. Occasionally, the computer does not have WiFi, can’t connect, or the driver is wrong.

Open Clash, the edge browser cannot be used , as shown in the picture below, click on the settings, and uncheck "Use secure DNS..."
Probably these reasons are because Clash uses a proxy, which changes the way the computer itself accesses the Internet. Changed some settings, resulting in an error, you can search for relevant information to solve this problem after the clash is closed and you cannot access the Internet! ! !

Pay attention to closing the clash before shutting down, or not letting the clash close suddenly, in this way, there may be problems before the agent or something is done!
