I saw this post on this website and this problem was the same problem I have.
But this problem wasn't solved, because it was in a other topic. So I want to give it a new try.
I adjusted this post a little bit. Sorry for my language. I'm dutch :)
My internet keeps dropping off! There is no phone plugged in the same plug, its not the wifi, because my PC is connected with a cable to the router, but it's the internet connection who's dropping off!
When it drops off the router shows an error message in the browser saying it have lost connection and to check that everything is connected properly.
I have tried replacing the filter but the same problem! I even resetted the router to it's defaults and installed it again, but it keeps dropping.
Sometimes I'm in a game and I get disconnection every 20 seconds. Then I can play 20 seconds again and it will disconnect for 20 seconds.
So I have to restart the router and it works again! until it drops off again. Its really really annoying!
Can anyone help?
