(I have encountered this situation recently. I live in a place where several people use a wireless router together, but these days, I suddenly can't open any page, and I can't log in to QQ, but the network status shows "connected", and the signal Still full. This is very depressing, so I searched for relevant questions on the Internet, but the answers are too many and too complicated, and the more I read, the more confusing it is, so I just calm down and summarize the solutions to the above problems, just for my own opinion. Everyone for reference.)
