Hi,
I'm running my athn(4) device in hostap mode. I noticed, when it's set to
802.11n, I get higher latency (pinging the OpenBSD AP) and disconnections
every few minutes. The Wifi clients are Linux-based (Android and Debian).
When I set it back to 802.11g (mode 11g) it's fine again.
I have athn0 using powersave on too, and when the client has powersave mode
on, the latency goes up and network performance also drops. As soon as I turn
powersave mode off on the client, it goes from being anywhere between
600-1000 ms per ping, to 1-2ms per ping.
Is there some issue with 802.11n clients when OpenBSD is in hostap 11n mode?
Also is powersave mode a problem. Has anyone tested these and come up with
a good solution? I've tried different channels (can't try 5 GHz because none
of my devices support it except the hostap device)
Relevant bits from dmesg:

Is there anything I can try to get 802.11n stable?
Thanks,
Tom
