[karmic] Acer Aspire 4530 ath5k does not work on boot

[Asif Youssuff]

After booting on any 2.6.31 kernel, I am not able to turn on the wireless radio on my laptop -- and thus cannot connect to wireless.

Trying to disable and reenable wireless also reproducibly causes NetworkManager to segfault.

After restarting NetworkManager, wireless still does not work.

After doing sudo modprobe -r ath5k and sudo modprobe ath5k and trying to turn on the wireless radio, I am able to connect to wireless.

This is a new issue with the 2.6.31 kernel.

These are the steps I followed after boot to get wireless working.

Checked nm-applet

no wireless network found

disabled wireless via nm-applet

enabled wireless via nm-applet

These messages come up in the system log.

nm-applet now says that wireless is disabled

pressing the wireless radio button does nothing

restarted nm with sudo NetworkManager

removed ath5k module with

sudo modprobe -r ath5k

Wireless now begins to work.

[Asif Youssuff (yoasif)]

Wireless also stops working on wake from hibernate, and I have to do the above steps all over again.
