[Bug 414560] Re: ath9k disassociates/reassociates a lot

[vientito]

What I have observed with this package linux-backports-
modules-2.6.28-15-generic is as follows:

system (am64) driver used: rt73usb
front-end:  wicd-client (wicd 1.6.2.2-1)
encryption:  WPA-TKIP

disconnection comes almost predictably at 18mins, 38min, 58 mins of
every hour.  Disconnection usually lasts for 5-10 secs and then it will
reconnect again.  Wicd-client still indicates connection during the
absence of signal.  Name resolution totally fails rendering everything
associated with internet silent.

What I have found is that when I disable NTP daemon in the background it
will rid of this problem to a large extent.  Except for temporarily
disconnection at 18 min at every hour, it seems much better than before.
The 18 min disconnection has to do with cron.hourly setting which tells
the system to run cron scripts at 17min though I have found no proof so
far (there are no existing scripts in cron.daily to execute at 17 min).

I say "almost predictably"  because 4 out of 5 times it will disrupt any
realtime online video I am watching.  Sometimes the video will come back
after the 5-10 sec disruption but almost everytime the video will freeze
and lose with broadcast server completely.

All symptoms disappear if I resort to wired connection via eth0 instead
of wireless modules.
