Here is whats happening, i tried to download the beta of a video game, it was a big file around 6gigs so i left the computer to download it over night, it was gonna take like 4-5hours. I came back to the PC the next day and the download had basically frozen and it said i was connected to the internet and all but i could not finish the download nor could i surf webpages. I rebooted the PC and everything worked fine. I tried ipconfig renew but it did not work. This seems to be happening with anything i leave to download longer than 30mins. I downloaded a patch for WoW last night only 450mb took like 42mins and same thing happened, same thing happens when i try to use bittorent too. I am running Windows 7 ultimate x64, amd duel core 4200, 2gigs of ram. I never had these problems with windows XP its only been happening with 7. thanks for any help.
