Bug Description

Wireless networking did not work when I resumed from suspend.

Using the indicator/applet to "Enable Networking" didn't associate my wireless with the AP. Plugging in an Ethernet cable did not bring back networking. The hardware rfkill switch did not bring back networking.

A reboot allowed me to associate as I expected.

Thanks

I've seen some reports about NetworkManager failing to work after suspend, and since none of your connections work I'd guess this is what you're seeing. Next time this happens see if restarting NetworkManager fixes the problem.

Seth Forshee, good news, bluntly restarting NetworkManager allowed me to continue without the reboot:

$ sudo service network-manager restart
[sudo] password for sarnold:
network-manager stop/waiting
network-manager start/running, process 6165

I didn't see anything in my logs that suggests what the error is.

Is 'linux' still the correct package? Or since restarting NetworkManager 'fixes' the problem, should this be re-assigned towards nm?

Thanks!

From what I see in the logs there's not even an attempt to establish a connection after resume, so I think the problem is likely with network-manager. Reassigning.

affects:

linux (Ubuntu) → network-manager (Ubuntu)

I have the same problem.

'sudo killall NetworkManager"

restores the connection.

This is the syslog for suspend and wakeup. The networkmanager didn't wake up.

Here's my syslog around another failure. I suspend in Nov 21, resume in Nov 22, and used "sudo restart network-manager" to bring networking back.

Thanks

I upgraded from 13.10 to 14.04 LTS but I can confirm that this problem still happens in 14.04 LTS.

sudo killall systemd-logind -> changed nothing
sudo killall NetworkManager --> fixed networking immediately.

Toggling the software "Enable Networking" in the NM applet did not work. Toggling the hardware rfkill switch did not work.
