That sounds like a driver issue or something in the kernel 802.11 implementation rather than something in hostapd. > Watching -dd output of hostapd shows nothing unusual. hostapd should not be involved during normal data traffic, so this is not surprising. Restarting hostapd will reset state in the driver and hardware/firmware and that seems to be sufficient to recover from whatever state the device reached. > What would be the best approach to debug/pinpoint the problem?

I'd look at the driver behavior rather than hostapd.. -- Jouni Malinen PGP id EFC895FA _______________________________________________ Hostap mailing list Hostap@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/hostap
