Subject: ath9k roaming for no obvious reason
Date: Mon, 20 Apr 2009 07:47:44 -0700	[thread overview]
Message-ID: <49EC8B10.7020006@symas.com> (raw)

I've been seeing this for a couple of months now, and updating to the latest 
wireless-testing git hasn't improved things:

This is on an HP dv5z laptop, lspci shows
08:00.0 Network controller: Atheros Communications Inc. AR928X Wireless 
Network Adapter (PCI-Express) (rev 01)

It's about 10 feet from a Linksys WRT54G and there's nothing blocking the line 
of sight. I'm running a 2.6.29.1 kernel at the moment; used the 
compat-wireless git to build the wireless stack.

At random intervals (15-20 minutes or so) it loses the association completely 
and NetworkManager asks me to re-authenticate. This behavior seems to have 
gotten worse in the current snapshot. Has anyone else seen this, any ideas?
