I don't believe that this could be a virus or registry issue, Maybe a Virus but i doubt it. Can you connect efficiently to the Internet via using safe mode? 

Make sure that the software on the computer is upto date i.e. NIC's. Then try to update the drivers that run the network in your house, Revert to factory settings.

Try this =)

so this stupid problem came back and it has nothing to do with the wire/connection

there are no registry problems according to Uniblue reg booster

and the only thing that i changed was the new ATI driver and i did that cause im only gettiign 40 fps in css( check my other post with ideas please lol)

Have you tried replacing your modem/router? My local ISP recently send me a new Pirelli modem that has the same issue. However if I do wait for 10 minutes or so it works (does need some time to reconnect) or I just restart the device which takes about a minute - try that. Recently I've aquired a Cisco 837 on ebay for 80 bucks - once configured it it works perfectly 24/7.

Ask your retailer if you can send the new device back if it does not help solving the issue. Lookout for any good modem/router from popular manufacturers like Linksys, Zyxel, D-Link, 3com etc. and make sure you get the right version for your internet connection ADSL/SDSL/VDSL and if ANNEX A/B/ISDN....

If it is a Hardware or Driver issue you could buy a cheap 10/100 PCI ethernet card. Mostly they have Realtek or Marvell chips and Windows has standard drivers that work quite well.

But I suspect it is a faulty modem/router.

solved. got a new mobo lol
