Title:
wireless authentication always times out after standby
Status in “wpasupplicant” package in Ubuntu:
Confirmed
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://wiki.gnome.org/Projects/NetworkManager/Debugging, I was able to get the
attached lines in /var/log/syslog.
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.
