Public bug reported: 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.
