Hi Emmanuel,

sorry for the silence, I wasn't at the university for a few days so
I couldn't test.

Now I did:
kernel 3.3-rc5

Disabling 11n and adding this parameter created loads of output, but
still makes the connection break down and reconnection does not work
anymore. I attach a (small) part of the syslog file. I had 
loads *LOADS* (200000+) of messages

in the log. Then there is something about "TX on passive channel"
and from then on everything goes off.

Apparently not.

Best wishes
