I have Dell Inspirion N5050, my internet was great until 5 days ago, he starts bugging first with wifi on my college have full signal but cant load web pages, videos... Or he disconnect or dont run or run slow. On my friend wifi its the same thing while my freind on several computers running great. I also check connection with usb modem, same thin esspecialy with videos i have connection while going on web sites like newspapers but cant load pics. I think its operating system I have windows 7 and Ubuntu Linux the last version, i didnt try Ubuntu dont have all drivers and didnt try ethernet connection so I need opinions is it OS problem. P.
