Hello,

After upgrading from 7.2 to 8.0-RC1 I see strange thing with my ath
wifi. I'm running WDS network and have two WRT54GL routers. After boot I
see my ath connected to the network and selected bssid
00:1a:70:4e:fd:12. Before I had about 2Mb/s using this bssid. But now I
see about 900Kb/s only. I'm getting better speed after using

  ifconfig wlan0 bssid 00:1a:70:4e:fd:12

Ok, some time later (note, I didn't reboot my notebook), trying to copy
big file, I see 900Kb/s again. And again

  ifconfig wlan0 bssid 00:1a:70:4e:fd:12

helped me. What I did wrong?

Thanks!
