That sounds like a MediaTek specific issue on the client devices.. It would be interesting to see a wireless sniffer capture showing the exact frames exchanged between the AP and station. I'd use an external wireless sniffer for that, but you might also be able to add a separate virtual monitor interface on the AP and use that monitor interface to capture the frames. For example, something like this: iw dev wlan0 interface add mon0 type monitor ifconfig mon0 up tcpdump -i mon0 -n -s 2000 -w /tmp/mon0.pcap -- Jouni Malinen PGP id EFC895FA _______________________________________________ Hostap mailing list Hostap@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/hostap
