How to fix wifi problems on linux?

Question

linux

It was kubuntu 15.04, I thought that the plasma was buggy, rearranged mint 17.2 but the problem is still the same. after a while, the Internet stupidly propodaet, and the connection to wifi remains active, but the bytes do not run back and forth. On kubunt, I solved the problem by stupidly reconnecting. but here it does not connect. I disconnect and I can’t connect to any wifi anymore. tested on 3 different routers. The connection hangs, then writes that the connection failed. The Internet disappears completely at random times, maybe after 5 minutes or maybe after 3 hours. with wifi itself everything is ok because everything plows on Windows

Answer 1

Time under Windows plows, yuzay Windows, or install lts. April 15 is not for those who ask such questions.
