I have a very strange problem. It started all yesterday about 5PM. I was downloading some stuff when I saw that the speed is going up and down. Couldnt play any online games because my ping would jump from 70 to 300 and back. It wasnt like that before yesterday 5PM. Everything was normal. 2 minutes ago I plugged in ethernet cable and there are no drops whatsoever. What eould cause this and how to fix it?
As I said, it started to do like that only yesterday
