I was able to reproduce this on 3.6.6-4.fc18, but not on updated 3.6.10-4.fc18, (which include fix for very similar bug 883414). Are you sure you run test on new kernel?
Comment 5 Jaroslav Škarvada 2013-01-04 16:06:03 UTC 
I retested with updated system (kernel-3.6.11-3.fc18). The only change I noticed the nm hotspot mode now use adhoc network mode (I think it previously used infrastructure, but I am not sure). In adhoc mode with kernel-3.6.11-3 everything worked as expected. When switched to infrastracture the same problem appear.
Comment 6 Stanislaw Gruszka 2013-01-16 10:46:39 UTC 
It's yet another problem, we do not correctly change interface type when switching back from IBSS to STA mode.

Fix for this problem, tested by myself.
Comment 8 Stanislaw Gruszka 2013-01-16 10:49:23 UTC 
Josh, please apply above patch as fix for this bug. I just posted it upstream and cc -stable too.
Comment 9 Josh Boyer 2013-01-16 13:32:43 UTC 
Applied on all branches.  Thanks!
