I can the test another AP (which happens to be Linksys WRT54*, v5 i
think) at work, which also has WPA enabled.
I will check for the firmware updates for my own unit.

Yes indeed, i did write in OP that the Linksys unit regenerates the
group key every 3600 seconds. So, after making connection (with the
ap), "TKIP ICV mismatch on decrypt" message is being generated after
2 hours (until iwi0 interface goes down).

What do i need to generate the output? Is setting MIBs
net.wlan.debug & net.wlan.0.debug to -1 enough?
