When the connection goes down I'm seeing a lot of "rx failed 'cuz of PHY err" and "CCK timing" errors. lab3# athstats 8894 tx management frames 5 tx frames discarded prior to association 887 tx failed 'cuz too many retries 13077 long on-chip tx retries 7 tx frames with no ack marked 9969 rx failed 'cuz of bad CRC 138910 rx failed 'cuz of PHY err 138888 CCK timing 22 CCK restart 1 beacons transmitted 39 periodic calibrations 1180 rate control checks 25 rate control dropped xmit rate rssi of last ack: 15 avg recv rssi: 44 1 switched default/rx antenna Antenna profile: [1] tx 7720 rx 29817 [2] tx 292 rx 37 With tcpdump -y IEEE802_11 I can see the packets, but without -y IEEE802_11 there is nothing.
