[Bug 599434] Re: Atheros AR928X wireless card not working after suspend

[Menachem Shapiro]

This is a bug in Network Manager. I recently experienced it and found the fix on the Ubuntu Forums, here:
http://ubuntuforums.org/showpost.php?p=9300002&postcount=4

to quote:
---------------
Check both of these, should be:

/etc/NetworkManager/nm-system-settings.conf

[main]
plugins=ifupdown,keyfile

[ifupdown]
managed=true

-------
and

/var/lib/NetworkManager/NetworkManager.state

[main]
NetworkingEnabled=true
WirelessEnabled=true
WWANEnabled=true
--------------

For some reason, when I restarted Network Manager after suspend, some of
the settings were set to "false" instead of "true". This is why
networking was disabled.

I changed them back to true and then restarted the computer. When I
rebooted wireless was working again. (There probably is a way to do it
without rebooting, but just restarting NetworkManager didn't work for
me)
