[Something went wrong with the computer]

As in the question, I said some time ago that my laptop couldn’t connect to the wifi in the bedroom. I thought it wasn’t a big problem, so I pulled a network cable and directly connected it to the router to force the internet connection. The wifi at home (the home is a public router without a network cable), suddenly realized that the problem was serious, I fiddled with Baidu for a long time and asked some friends for advice, and finally said that it should be the problem of the notebook itself. I am a computer blind and can’t understand it. I’ll take a look at it during the day… I’m sorry
