Disconnect On Certain Sites

I experienced this problem a while ago but didn't think much of it. But now it really starts bugging me. Whenever I visit sites like xhamster or any other tube site (with the exception of youporn and a few others), my connection gets somewhat lost. I still have a green light from my router but once I'm on one of those site, it won't load anymore and the same goes for every other page I try to access afterwards. I have to restart the router again to have any site load again. Anybody knows what the problem could be?

It is their pop-ups that knock your router out, it is a real problem if you run windows 7

Google it.
