Not seeing the AirPort Extreme's ...

I having issues with my AirPort Extreme. I'm not sure exactly where the issue is so I'm posting here for some suggestions.

Basically, I'm running a MacBook Pro (see below for stats) with an AirPort Extreme base station (model before dual-band, N-draft capable, latest firmware). I don't think my laptop is broken because I can see the neighbor's network, though it's just out of reach for me to connect to. The problem is, my AirPort says it's fine. I tried restarting, uploading new firmware and even went as far as bringing i back to factory settings.

The problem is, the light still is green and I still don't see a network. To make things more interesting ethernet seems to be working fine (I'm using it now). I'd love to test another computer on the network so I can be sure the laptop isn't the problem but at the moment I'm the only person with a computer that can be used (dad's got a nasty virus). I'll be trying my computer on a different network tomorrow at work so I can verify it then.

That's one other thought I've had. I went down to grab my dad's laptop and see if it could connect when he told me to leave it because something was running havoc on the system a little bit before I lost my connection suddenly.

I lost the connection while running Windows, by the way.

I don't think the two are connected or that if they were it's something a factory reset couldn't fix.

I'm out of ideas. Can anyone make any suggestions? Specifically how to double-check to make sure the AirPort isn't broken and doesn't know it?
