Following works for me for my Sony Vaio (even when enabling energy
saving option for ath9k driver). I collected the script information from
various sources - the last missing thing for my Vaio seemed to be the

The solution in comment #92 worked for me and, in contrast with comment
#91, for me it was essential to keep the pkill -f wpa_supplicant line.

I get working wifi. Unfortunately it fails after a while again (without suspend
or power save, just in the middle of surfing). Likely my issue this is now more
related to i.e. Bug 1320070
Thanks for all your work.
I tracked down the issue where WiFi would fail after suspend in that it
doesn't associate anymore (tries to connect but fails), and it's a bug
in wpa-supplicant that was fixed in the current version (Ubuntu uses
2.1, newest is 2.3). Replacing Ubuntu's wpa-supplicant 2.1 with Debian's
I see it on a laptop that does not connect automatically to the wireless
network after wakeup. But I have the same issue also with a desktop with
wired ethernet. So a more appropriate title would be 'network manager
fails to reconnect after resume', because the issue is not wifi
specific.
After
As a further note, the script by aztecjoe works around the issue just
fine.
I would recommend delivering it via an updated network manager package
and not waiting for network manager to have the issue fixed. If and when
the issue is fixed in network manager, the redundant restart should not

The issue started recently (early November 2014). I had been running
14.04 since July without this issue. So an automatic update has
infected my setup since early November.
The work around was to create the file 04_bug_network_manager_restart in
directory /etc/pm/sleep.d. See terminal listing

I've found, as a work around, sending a kill -hup signal to the
wpa_supplicant process will 'wake' it up and network connectivity will
get restored again

The problem seems to occur after kernel updates. NetworkManager needs to
be restarted ('sudo kill PIDforNetworkManager) after suspend.
