Connecting a PC to Airport Extreme

[Afflicted Max]

My mom has a Compaq Presario CQ60 (here).

I just set up AX, and my iMac and Macbook Pro hook up to it wirelessly with ease. But the PC will connect, but refuses to connect to the internet.
The network securtiy is WPA2 - Personal.

I've powercycled a few time, with no avail.

Is there a missing driver or something?

What version of Windows are you running? Is your mom's computer getting an IP address? If so, is it statically or dynamically?

I have it working now somewhat.

I just updated it to Windows Vista Service Pack 2. However, there is a lot of intermittent disconnections. I personally don't mind it, but my mom sure as hell will.

I currently have the AX giving off two signals. 2.4ghz and 5ghz.
This laptop is connected to the 2.4 with WPA key. I also have two cordless phones, I don't know they're frequencies, but I'll look into it.
The 2.4ghz is running on channel 11, I believe. I may change that to automatic though.

Any other advice?
