I'm no expert, but if it were me I would

1. Try turning off WPA on the modem,
which you can probably do through its web interface,
on 192.168.1.254 or something like that.
Use WEP instead, for the time being.

2. Try turning off NM (NetworkManager) with chkconfig.

3. Or maybe the problem is the network service.
Try turning that off with "chkconfig network off".
I think NM and network sometimes get in conflict if both are on.

4. Use a cheap PCMCIA WiFi card temporarily
instead of the inbuilt card.

I have a somewhat similar problem with a USB WiFi dongle,
which crashed the system if attached on bootup,
but which worked if inserted later.
(But this had nothing to do with WPA or NM.)
