I can't for the life of me figure out what's going on. My wireless card is able to connect to my network, however Windows lists the connection as "no internet access". After going into my wireless card's utility program, I see over 90% of the frames received have CRC errors. I have tried two separate wireless cards, both PCI and USB, with the same result.
Additionally, I'm fairly sure it's not the router since both my laptop and my roommate's laptop can connect to the internet without issue. Is there any way a software problem (perhaps a virus?) could be causing this? I don't mind doing a fresh install of Windows, but I would rather not if I don't have to.
