Ah, looking again, I'm subscribed to the first, but it's not what I'm
describing.  That one is that both WEP and WPA fail.  In my case, it
just fails with NetworkManager with WEP. WPA is fine.  There's a bug
sitting around for that too, though.

https://bugs.launchpad.net/ubuntu/+source/linux-ubuntu-modules-2.6.22/+bug/139080

It's filed in Feisty and Gutsy, but it still exists with Hardy and
iwl3945.  With that laptop, WEP went like this:
Dapper + ipw3945 + network-admin = works
Feisty, Gutsy + ipw3945 + NM = fail...WEP key not accepted
Hardy + iwl3945 + NM = fail...WEP key not accepted
Hardy + iwl3945 + network-admin = fail...WEP key accepted, no ip address
Hardy + iwl3945 + iwconfig + dhclient = works

I haven't bothered trying to use the GUI with my iwl4965 and WEP.  I
just expect NM to not work when it comes to WEP.
