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).

Hmm, perhaps iwl4965 device does not work well with the new PCIe chipset.

Does any of fallowing workaround the problem?

kernel boot parameter:
pcie_aspm=off
pci_aspm=force
pci=nocrs
pci=use_crs

iwlegacy module parameter:
bt_coex_active=0

iwl4965 module parameters
11n_disable=1

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.

There should be 3 or 2 antennas: 1 - white, 3 - grey, 2 - black,
connection on adapter should match cable color (ok, I don't know if
it does any difference, but it worth to try). If there is only one
antenna available, perhaps there is somewhere another miniPCIe slot
where are more antenna cables available. But, if there is really
only one antenna cable, it should be connected to number 1 (white)
adapter connector.
