Description Omar Siam 2012-04-05 12:26:19 UTC
It seems that ipw2200 some sort of automatically supports nl80211 but it doesn't report any encryption capabilities back to userspace or at least not in a way network-manager understands (see nm's src/wifi/wifi-utils-nl80211.c)
I reported this bug to ubuntu developers. They asked me to file this here.

This bug does exist in a kernel compiled from linux-stable.git using tag v3.2.14.

Assigning to myself.
Comment 3 Omar Siam 2012-04-11 20:50:58 UTC
The posted patch fixes the problem I reported, but if that's fixed nm still doesn't show the signal strength of the connected network I guess (because once created using some patch nm can connect to this network but doesn't show any signal strength). I'll file another bug if I really run across that problem. Not a show stopper anymore but not working either. As was said: probably will not work
through nl80211.
