Wireless interface is corrupted on fresh install/update of OEM Vista

I don't really know where to begin but I'll say this first: I recently switched back from Fedora Linux to Vista 32bit Home Premium, which came with my laptop (a Toshiba Satellite) - and restored my old OEM activation for this purpose. I've updated it with everything possible through Windows Update, but one thing still gives me a problem - the wireless. It hasn't been able to "see" any networks in range, nor accept imported profiles through netsh (it gives me a 5023 error.) A quick check of the interfaces through netsh reveals that the interface name is corrupted. I've already flushed and reset the winsocks, but I've never been able to bring up the wireless using ipconfig /all. This happens with both the built-in card (Atheros AR5007EG, updated through Device Manager) and a Netgear WG111v3. If I hit "Diagnose and Repair" it says that the wireless does not correctly recognize the IP protocol and tells me to go to the properties menu in order to put check marks beside IPv4 and IPv6, but they're already checked. I've been using the Ethernet modem in the mean time, but sitting on the floor sucks so . . . any help here? I'm close to either copying wlansvc.dll from another computer in the house or reinstalling Linux. I'd really appreciate something to go on.
