I also have an Cisco Aironet 350 and the only time I had such an issue was connecting to a WPA enabled AP and a recent (couple of months) firmware update from Cisco corrected this issue. Given that you're using 5.4 and WPA is only coming out in 6.0 I know this is a long shot but I would try updating the firmware of the card. Heck, every update I do gives me more speed and stability :) -- Joao Barros _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
