Public bug reported:
The Atheros wifi in my Acer 5051 notebook most of the time works like a
charm. Once in a while however, wireless networking isn't available from
nm-applet anymore. Rebooting once doesn't usually fix the problem. But
for some reason, most of the times it works after 4-5 reboots.
I had this same problem regularly over 6 months ago. Last six months
everything worked fine.. I guess that since my upgrade to Hardy the
problem started reappearing.
I noticed the following error in dmesg:
[ 52.964098] wifi%d: unable to attach hardware: 'Hardware revision not
supported' (HAL status 13)
lspci -vv:

According to the sticker on the notebook the wifi is 'Atheros AR5BMB5'.
Not sure whether this corresponds with the info lspci gives?
Please let me know what further info you guys need..
