Vista cannot find ANY wireless networks, functional network card

Hey, I've been looking around for an answer for this, but everyone's problem seems to be a bit different.
I have a new Toshiba Satellite that dual boots Vista x64 and Linux. Everything was fine and dandy (excluding, of course, the usual Vista wireless errors that were repaired with restarts, etc.) until a couple of days ago. My Windows will no longer detect ANY wireless networks, including my automated one, even though I know there are several in range. I think the connection software literally says it can't "see" any. This isn't a hardware or router issue as my Linux side connects just fine. Any ideas?

Recently one of the folks in the office I do tech support for couldn't connect to the ethernet/wired cable. Both wireless and ethernet were enabled. We disabled the wireless, and the ethernet connection was suddenly there.

Evidently the 2 will fight over making a connection. With neither winning.

My suggestion is to check your ethernet connection under network places and make sure it is disabled.

If it is already disabled, I don't know what else to check.
