I am not running NM. Just plain wpa_supplicant and dhclient. However I
do have a suspicion that this is faulty firmware on my card and that
this messes things up. I had been doing testing with WiMAX and I run
into some issues and was speculating about interoperability. I started
testing with unreleased firmware. That would indeed explain why I don't
see this kind of issues with any other dongle I attached to the laptop.
I will reboot into a kernel that uses the official firmware.

Regards

Marcel
