rx frame header question

[Beat Naef]

My one of my access points is showing numerous error messages of the
following form:

Nov 21 18:09:35 localhost kernel: wifi0: Could not find STA
00:02:6f:05:53:67 for this TX error (@199388)


After running prism2_param wlan0 dump 1 = dump RX frame headers I was able
to capture a fair number of rx frame headers. Below is a sample record:

Nov 21 18:10:47 localhost kernel: wifi0: RX status=0x0000 (port=0, type=0,
fcserr=0) silence=3 signal=29 rate=20 rxflow=0; jiffies=206638
Nov 21 18:10:47 localhost kernel:    FC=0x0080 (type=0:8) dur=0x0000
seq=0x41c0 data_len=47
Nov 21 18:10:47 localhost kernel:    A1=ff:ff:ff:ff:ff:ff
A2=00:02:6f:05:53:67 A3=00:02:6f:05:53:67 A4=51:c1:45:20:d8:dd
Nov 21 18:10:47 localhost kernel:    dst=b0:fc:ab:ec:31:cf
src=85:d8:9b:0d:ef:8f len=47

The fields A4, dst and src contain mac addresses that I do not recognize.
Currently the invalid misc counter is at 37354 and rapidly growing. The rx
invalid crypt counter is at 43 and the tx excessive retries counter is at
145. The last time I rebooted was about one hour ago.

Any idea what may cause these corrupted frames and error messages?

Below is a more extensive collection of records as well as bootup
information.


With kind regards
