Bug Description
After updating from saucy to trusty, putting the system to standby makes wireless stop working after wake up. Rebooting the system fixes it until next time standby is entered.
I've tried various hints about unloading modules, restarting the network-manager service or nm-applet, nmcli nm sleep false
or using rfkill / the hardware kill switch. None of these changed the behaviour or seemed wrong. After following https:/
The driver works fine after wake up and scanning for networks works too. Upon trying authentication, the request fails after 5 seconds with a timeout. I managed to make the connection working again by killing wpa_supplicant so it must somehow be stuck.

A quick and dirty workaround is changing line 15 of /usr/lib/ pm-utils/ sleep.d/ 60_wpa_ supplicant to read

$WPACLI terminate
instead of
resume|thaw)
$WPACLI resume
