Hmm, on my experience, software sucks much more than hardware, but we
never can exclude hardware problem. I'm not sure if there are divergence

Me neither unfortunately...

Christoph, you mentioned that you replaced you 
motherboard. Did the problem start to happen after that?

Yep,... the old board broke (and the system didn't bot anymore at
all)... it was replaced with a new one by the manufacturer... and
starting with that (with no software change on the disk in the meantime)
the wifi didn't work anymore (as described).

Did you
correctly connect antennas cables to adapter.

yep... at first (when they sent it back to me) it was not connected at
all... I connected it... the problem persists in both states, connected
and unconnected.

Does adapter sits
tight in the mini PCIe slot?

yep

No, that's not needed if there are no good logs for compare. If possible
try on some very old kernel, first kernel with iwl4965 support was 2.6.24.

I'll have a look...

Chris.
