so I had time to log the details now. I still have the problem that the
association only works once. If it ever breaks it never works again. I
hope this is not something stupid in the iwlagn driver for the 5350
hardware.
This is from wpa_supplicant (latest version from GIT of course):

As you see it keeps scanning, authenticating, associating and then it
never completes.

Do you need anything else? I have really no idea what happens here and I
