disconnections

I've been experiencing this problem for some time now, and I've tried everything to fix or at least limit the amount of disconnections I get. Either browsing the internet or playing a game online, I continously get disconnected. These are the things I've tried to improve my connection...

Well i recently started playing again (weee i love it) and everytime i join i server after about 30 mins i either crash...or disconnect...I have no clue whats going on but it's pretty annoying (resetting score/PL or even full server i was just in) *EDIT** All my drivers are updates No error...
