I searched and I cannot find a situation that matches mine exactly (or perhaps I didn't look hard enough). I will try and be as specific as I can. I will be doing my business and suddenly, my internet will stop. It's important to note that the disconnect warning will not pop up. According to the computer, it is still connected. When in Firefox or IE (tried both), when I click on any link it says "done" at the bottom instantly and nothing shows up. It doesn't say "unable to connect". It doesn't say "can't find the address". It just says "done" at the bottom of Firefox but nothing connects. It doesn't search. It doesn't load. As said, this happens with both IE and Firefox. Oh it gets better. Torrents and any other sharing programs will also shut down and often, if I go to bed with torrents running, they will dead by morning. The only solution has been rebooting. I have turned off every program. I have purchased a new router. I have run ipconfig /release and /renew and this does not solve the problem. Internet will still work with other computers tied to the network (like my netbook with XP). I have loaded new drivers and rolled back to older drivers. Nothing Here is the real kicker... If I reboot the PC...I can turn on the torrent program on its own and it will work without interruption throughout the night. It is almost like if I run multiple programs which access the internet, the PC has a nervous breakdown. I received the Win 7 RC earlier this year and I plan on purchasing the full version soon but I want to make sure this problem is not the PC or else I am almost better to buy a new PC and have Win 7 included. This problem only started occurring about three weeks ago, being reliable and lovable for months until then. So, any ideas?
