I've seen multiple reports for this bug on Ubuntu, yet no solution. In this case, the network is recognized but I can't connect.

(No, it's not a router/driver issue.)

Are you in the US? If so, the current standard is channels 1-11 for 802.11b/g. You will not be able to use the upper level channels. See… for more information. – CraigM Aug 30 '11 at 18:28
Nope, I'm not in the US. – seriousdev Aug 30 '11 at 18:32

This might be a way to work around this:


Put the following line in your /etc/modprobe.d/options
options cfg80211 ieee80211_regdom="EU"

Then reload the module iwl4965 or iwl3945 and channels 12 & 13 should work
