it seems that I have the same hardware and the same problem. While a
device using run can connect to my access point without problems, iwn
is not able to connect anymore. But, it connected earlier without any
problems to other access points. iwn never hangs in my case, it is
simply not able to connect.

With the same configuration, run0 connects without problems.

How could I help to fix this problem?
