I'm having trouble with my laptop Internet connection. It's patchy at best and resets or freezes a lot. The signal strength is also random. I thought it might be a driver issue but now I don't know.

Three other computers using the same wireless network run well.
I've switched out wireless routers so I don't think it's the router.
I thought it might be the laptop's internal wireless card but I just bought an external USB network card and I'm still having problems.

Specs
Lenovo T-60p
Windows 7 Ultimate Edition
Patches/drivers are up to date

I only use one of the below at a time, disabling the other:

Intel PRO/Wireless 3945ABG v. 13.3.0.137 (Internal wireless)
Medialink Wireless-N USB 2.0 Adapter (USB wireless)

Any ideas on what might be the problem?
