Comment 34 for bug 24776

I have the same on my Dell D800 with Intel Pro 2100. I was not able to get it to work with WPA-PSK. In order to test I created a wpa_supplicant.conf file and started the wireless network manually. I indeed got the same error messages as you get:

ipw2100: Fatal interrupt: Scheduling firmware restart

I then started to play with the signal strength setting on my Cisco ap1231 access point. To no avail. The AP has a b/g radio in it, so I decided to turn off all but 1 and 11 mbit/s speeds and leave the other options as enabled, but only 1 and 11 required. The link came straight up. Before that I had all speeds set to required. So it seems like there is something fishy about speed negotiation when you're running a 802.11g network.

I've attached the output of:

uname -a > uname-a.log
cat /proc/version_signature > version.log
dmesg > dmesg.log
sudo lspci -vvnn > lspci-vvnn.log
