I fully expect that this AP is not behaving perfectly, but that is of course irrelevant in the scope of ath9k when ipw2200 ath5k orinoco_cs can deal. If anything, the AP is valuable for debugging ath9k, which is also why I prefer not to change the AP until it seems like all issues have been solved. (But I've had plenty of problems with ath9k also on various other APs, just no logs from anything else today.) > If you bring up a monitor-mode interface, Then I got some new suspect messages in the kernel log. But internet and monitor both work. dmesg output in log8_after_iw_dev_eth1_interface_add_wmon0.txt > do you see beacons at a sane, regular interval? 100ms, with some missing ones. (3 missing in 327 received, second test 13 missing in 819 received over 93 seconds. Seems to match the beacon loss messages.) //Peter --B7FF+pnjRCrp0ISR Content-Type: text/plain; charset=us-ascii Content-Disposition: attachment; filename="log8_after_iw_dev_eth1_interface_add_wmon0.txt" [ 6454.002053] eth1: detected beacon loss from AP - sending probe request [ 6456.004646] eth1: detected beacon loss from AP - sending probe request [ 6456.077272] eth1: cancelling probereq poll due to a received beacon [ 6467.002036] eth1: detected beacon loss from AP - sending probe request [ 6467.029043] eth1: cancelling probereq poll due to a received beacon [ 6471.002043] eth1: detected beacon loss from AP - sending probe request [ 6471.123295] eth1: cancelling probereq poll due to a received beacon [ 6479.002039] eth1: detected beacon loss from AP - sending probe request [ 6479.415183] eth1: cancelling probereq poll due to a received beacon [ 6484.004933] eth1: detected beacon loss from AP - sending probe request [ 6484.429046] eth1: cancelling probereq poll due to a received beacon [ 6499.002036] eth1: detected beacon loss from AP - sending probe request [ 6505.004023] eth1: detected beacon loss from AP - sending probe request [ 6505.411352] eth1: cancelling probereq poll due to a received beacon [ 6517.002038] eth1: detected beacon loss from AP - sending probe request [ 6519.002038] eth1: detected beacon loss from AP - sending probe request [ 6521.004032] eth1: detected beacon loss from AP - sending probe request [ 6523.004046] eth1: detected beacon loss from AP - sending probe request [ 6526.004664] eth1: detected beacon loss from AP - sending probe request [ 6528.004664] eth1: detected beacon loss from AP - sending probe request [ 6530.004659] eth1: detected beacon loss from AP - sending probe request [ 6532.004659] eth1: detected beacon loss from AP - sending probe request [ 6534.002031] eth1: detected beacon loss from AP - sending probe request [ 6538.002035] eth1: detected beacon loss from AP - sending probe request [ 6538.060097] eth1: cancelling probereq poll due to a received beacon [ 6539.002032] eth1: detected beacon loss from AP - sending probe request [ 6539.083602] eth1: cancelling probereq poll due to a received beacon [ 6563.004041] eth1: detected beacon loss from AP - sending probe request [ 6584.002040] eth1: detected beacon loss from AP - sending probe request [ 6590.004666] eth1: detected beacon loss from AP - sending probe request [ 6590.363990] eth1: cancelling probereq poll due to a received beacon [ 6594.004665] eth1: detected beacon loss from AP - sending probe request [ 6596.004659] eth1: detected beacon loss from AP - sending probe request [ 6596.196543] eth1: cancelling probereq poll due to a received beacon [ 6603.002037] eth1: detected beacon loss from AP - sending probe request [ 6603.055257] eth1: cancelling probereq poll due to a received beacon [ 6611.004043] eth1: detected beacon loss from AP - sending probe request [ 6611.343697] eth1: cancelling probereq poll due to a received beacon [ 6621.002035] eth1: detected beacon loss from AP - sending probe request [ 6621.476484] eth1: cancelling probereq poll due to a received beacon [ 6625.004032] eth1: detected beacon loss from AP - sending probe request [ 6630.004657] eth1: detected beacon loss from AP - sending probe request [ 6630.073998] eth1: cancelling probereq poll due to a received beacon [ 6636.004675] eth1: detected beacon loss from AP - sending probe request [ 6636.112735] eth1: cancelling probereq poll due to a received beacon [ 6644.002030] eth1: detected beacon loss from AP - sending probe request [ 6644.198491] eth1: cancelling probereq poll due to a received beacon [ 6673.144321] ath: Failed to stop TX DMA in 100 msec after killing last frame [ 6673.144357] ath: Failed to stop TX DMA!
