Hello.
I'm not quite sure what happens so I'll just dump here what I have in
mind so it would be easier to sort out later.
I upgraded from 11-STABLE to 12-STABLE and my card is now working in HT
mode. And that is nice. Currnently it's detected as:
ath0@pci0:4:5:0: class=0x028000 card=0x2093168c chip=0x0029168c
rev=0x01 hdr=0x00

device = 'AR922X Wireless Network Adapter'
class = network

Debug enabled:
dev.ath.0.hal.force_full_reset=1
dev.ath.0.hal.debug=1
Everyting I see in logs is:
Nov 15 19:45:54 limbo kernel: ath0: stuck beacon; resetting (bmiss count 4)
Nov 15 19:45:57 limbo kernel: ath0: stuck beacon; resetting (bmiss count 4)
Nov 15 19:46:04 limbo kernel: ath0: stuck beacon; resetting (bmiss count 4)
Though this happens all the time.
What changed after going to 12-STABLE:
1. HT works.
2. Devices are losing connection constantly.
Sometimes devices are getting back on the network by themself. Sometimes
this requires interface down/up. That's so fast so that tcp connections
are staying intact. But sometimes putting server interface down/up is
required so the others can talk to it. On the other host I see interface
trying different channels, then hitting correct one, waiting a little
and going back to trying other channels. On correct channel it shows
status: no carrier, just sits there longer.
It also looks like some devices have a good connection while others are
losing connection. There's one device that never gets off.
Thanks for any pointers.
