[Bug 549827] Re: ath9k: Sometimes cannot establish wireless connection on the first attempt after login

[Ilya Volvovski]

I have very similar behavior, happens several time during a day. It
happen with 9.10 but it became more frequent with 10.4.The major
difference with the original report that a successful connection is
always established after reboot.

On some occasions both wireless and wired connection exist, but no ip is
accessible. eth0  always restores normal operations as soon as I restart
networking service (disable/enable  through Network manager applet), but
it doesn't help wireless connection could not be established, even
though a network is available and signal strength is around 50%.

After I tried to reload ath9k driver and I could reconnect, though it
takes 10-15 seconds (is it normal?)

dmesg is very similar to what was presented in the original report. Any
other information you need?

Thank you
