    Hey i created a script in /etc/pm/sleep.d with this code and made it executable. still it doesnt work for me

    I am using a Belkin F7D1101v1 wifi adapter with my PC running Ubuntu 14.04 with all latest updates. My pc doesnt connect to WiFi after resuming from suspend and I either have to unplug and replug my wifi adapter or restart ubuntu. Any other fix?

    PS - even doing sudo restart network-manager from terminal after resuming from suspend doesnt work.

    You are a lifesaver, shrodi! I'd tried so many other things and this is the only thing that worked!

    Just found this thread. I had a method that seemed to work most of the time that involved turning counter-clockwise three times, disable wifi, manually suspend, recite a sendmail.cf config, sprinkle 5cc of mouse blood over the keyboard and power back up.
    Thank you Shrodi, your fix makes it much faster

    thumbs up Shrodi

    I just added this line

    "nmcli nm sleep false"

    into one of my existing sleep.d scripts and it has solved my issue. This fix works well on my Sony UX which I just updated from 12.04 to 14.04.
