Hi,

New list member.  Sorry if any of this is redundant.

I lose wifi connection after a few minutes or a couple hours, varies widely.

# lspci says...
04:00.0 Network controller: Atheros Communications Inc. AR9285
Wireless Network Adapter (PCI-Express) (rev 01)

# uname -a
Linux u888 2.6.32-21-generic #32-Ubuntu SMP Fri Apr 16 08:10:02 UTC
2010 i686 GNU/Linux

Not using any WEP or WPA etc.

Ubuntu 10.04 but also had same problem under Karmic.  Running 32-bit
right now but also had same issue under lucid amd64.  Computer is a
Gatway LT3103u.  Here are some dmesg warnings[1].

I did do a couple searches of the mailing list- the closestI could
find to my issue was the Amit Sood thread "[ath9k-devel] Need to
reload ath9k module" of Sept 2008, but that's an AR5K chip

Is this a known issue?  Is there something I can do to help track it
down?  Should I run a newer kernel or driver?

Best Regards.
