Does this suggest a solution > to you? I will try to get the wlandebug output tonight. I don't know whether you are still interested to track down the wired problem you had experienced. If you have time please try following patches: revert the old patch at your AP side and try this one http://people.freebsd.org/~sephe/rt2560_test.diff1 apply following patch at you STA side http://people.freebsd.org/~sephe/ieee80211_input.c.diff Best Regards, sephe --=20 Live Free or Die
