Thank you Stefan, your suggestion from comment #4 helped me too on my Thinkpad T60 with trusty and iwl3945 driver.

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. $ lsb_release -rd Description: Ubuntu Trusty Tahr (development branch) Release: 14.04 (current today, April 10th 2014) wpasupplicant version is 2.1-0ubuntu1 System: Lenovo Thinkpad R61 Wireless Driver: iwl3945 $ uname -a Linux <hostname> 3.13.0-23-generic #45-Ubuntu SMP Fri Apr 4 06:58:38 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/wpasupplicant/+bug/1305857/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
