Hi! When this happens, can things re-associate? Can yuo do this: sysctl dev.ath.0.txagg=1 (and dev.ath.1, dev.ath.2, etc if you have more than one physical atheros NIC in your AP) and paste the results? -a On 5 September 2014 06:24, Alex Deiter alex.dei...@gmail.com wrote: Hello, Please help me figure out what's wrong: FreeBSD 11.0-CURRENT r270733M amd64, PCI / Atheros 9227, 802.11n hostap mode Time to time network traffic between clients and AP stops: Sep 5 16:18:31 blackbird kernel: wlan0: [84:7a:88:70:c6:cd] power save mode off, 1 sta's in ps mode Sep 5 16:18:31 blackbird kernel: wlan0: [84:7a:88:70:c6:cd] ath_rate_findrate: switching quickly..
