I got a used computer I've been restoring and I have a weird situation:
When I first got it, I had no problems connecting wirelessly with the D-Link DWA-140 adapter. Once I loaded the drivers for my ethernet card, I disconnected the wireless adapter because I'm now physically wired and don't really care.
'Just for fun' I reconnected the wireless adapter about a week ago. It seems to be working fine (no hardware or driver errors when I search) but when I search for wireless networks, it just comes up blank every single time. I know there are SEVERAL wireless networks (I can see them on my phone, Blu-ray player, etc.) and I'm connected to my network on my phone and the router is literally next to my PC.
I feel like I'm doing something very basic wrong. I tried monkeying around in Windows Networking, which I feel is really dumbed down. I ended making my wired connection go away and was unable to restore it (I did a quick system restore with an image I created recently and it worked again fine.)
I'm running Windows 7 64-bit with all updates installed. I'm using zonealarm free and avast! free, with all updates installed as well.
