At a high level, I have the same problem: Network Mnager does not work anymore after resume, about half the time.
My work around is to run in a terminal: sudo restart network-manager As a side effect, nm-applet sometimes crashes when I do that. But it works. At a lower level, I am not sure if my problem is the same as the original poster; I am not familiar with Network Manager so I have not yet bothered to dig deep into the logs to figure out what is going one. I could post the logs if requested. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1310595 Title: network-manager and wifi not working after resume from suspend Status in network-manager package in Ubuntu: Confirmed Bug description: After resume from suspend, wifi light stays off but wifi connects. After resume from suspend second time, wifi does not connect and network -manager says network not activated, activate network does not help. only reboot does. additional info. I added: # WORKAROUND: always set the default hibernate mode first (normal mode) # (not required if you have the patch mentioned by Rohan below (http://askubuntu.com/a/344879/169)) HIBERNATE_MODE=platform # Always use hibernate instead of suspend, but with "suspend to both" if [ "$METHOD" = "suspend" ]; then METHOD=hibernate HIBERNATE_MODE=suspend fi # Make sure to use the kernel's method, in case uswsusp is installed etc. SLEEP_MODULE=kernel to /etc/pm/config.d/00-use-suspend-hybrid to be able to suspend to disk. Without this file wifi connects after resuspend but as said without wifi light on.
