[Bug 1286552] Re: No wifi after suspend
My comment #41 above does not fully apply. It turned out that removing
"iwlwifi" from SUSPEND_MODULES="" in /etc/pm/config.d/config (I had to
add it in 13.10 in order to get it working) fixed the issue for me.
However this seems to imply that unloading the driver will break wifi,
even if network-manager is restarted. My install was not a fresh install
so I cannot judge if that would work either.

Bug description:
After suspending ubuntu the wifi doesn't work. The solution given here
(http://askubuntu.com/questions/368671/ubuntu-13-10-wifi-not-re-
connecting-after-suspend) worked for me but when I have updated my
Ubuntu now it won't work. I have tried to test mainline kernel but it
won't to boot with it.
To reproduce the bug : just suspend the computer and then power it.
There's no wifi network until you restart the computer.
