I run Ubuntu 13.10 (though on 13.04 situation was the same) on Thinkpad E125 laptop

I have very common problem - there were no WiFi after suspend. I've googled the problem and find solution that works perfectly - http://www.webupd8.org/2013/01/fix-wireless-or-wired-network-not.html - after following those recommendation I have probably 100 suspend/wake-up cycles - WiFi always worked

But this fix didn't affect hibernate - now I have 100% times not working wifi after hibernate. If after hibernate I go to suspend and back - wifi start working again.

Can some please advise the way to apply that patch to hibernate

Try sudo killall NetworkManager, as suggested in Network devices unmanaged after resume from hibernation in Ubuntu Gnome 13.10 . It works fine for me!

This issue seems to be caused by bug #1184262 . It is not related to the networking as such, but to power management.

The workaround I found was to create a file with: sudo gedit /etc/pm/sleep.d/10_resume_network and paste the following:

#!/bin/sh
#Tell Network Manager that resume was successful

case "$1" in
       thaw)
         nmcli nm sleep false
         ;;
esac

Then, save and close the file and enter sudo chmod +x /etc/pm/sleep.d/10_resume_network.

  • this solution messed up my laptop for a minute. I had to restart in recovery mode because /etc/pm/sleep/d is mounted as read only so I couldn't just delete the file as root when it completely tanked my network manager – gloomy.penguin Nov 1 '18 at 22:32
