Interesting. For further analysis would be useful to have copies of the
frames exchanged during association. You can capture these frames by
letting the following command run while iwm0 moves from down state to UP
and associates:
tcpdump -n -i iwm0 -y IEEE802_11_RADIO -s 4096 -w /tmp/iwm.pcap
You can send the resulting /tmp/iwm.pcap file directly to me. Thanks!
