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

[Kunal Gangakhedkar]

@notoriousdbp,
Well, I don't think ubuntu guys can do anything for the issues here. I've tried to take up the matter with the atheros guys on ath9k-devel list and they haven't been all that helpful which doesn't go well with the whole open source nature. They just stopped responding - even for the casual status-of-the-development queries.  :(
UNLESS the ubuntu kernel team decides to push it with the atheros guys, but I doubt it will work..

The way I see it is - for the 'wife and daughter' cases, the driver is
pretty much usable - considering the typical usage pattern of casual
web-surfing and chit-chatting here and there. I doubt those are right
candidates for heavy wlan traffic which is the problem now. The
disconnects are pretty rare these days with the current compat-wireless.

The only time the driver still craps out is when NM does a background
scan while there is a transfer going on - unfortunately, the AR9285 chip
seems to be one of the 'cheap' ones which requires a full reset even for
a background scan and that's the main cause of the stalling transfers.
And of course, the power-management implementation sucks too..

@all, 
Note that the driver is still *not* fully stable - it still does crap out from time to time for some weird unknown (to me, at least) reasons. But, it is improving - slowly but steadily - so, there is hope :)

Wish I had some know-how of the 802.11-land to see where the driver
needs the fixes. Unfortunately, I'm a storage guy with absolutely no
understanding of 802.11.. :(
