Network manager wifi off after suspend

When I put my laptop in suspend and then wake it up again some time later, the wifi is off and I have to manually enable it.

This is a small annoyance that has bothered me for some time now. I have tried several fixes, like creating a service file that restarts network manager after I resume and some other fixes I can not remember correctly. I have all fixes removed now so everything is clean again.

I read that with pm-utils suspend suspending the wifi driver specifically might work. However I use systemctl suspend, will the same fix work here? And if so, how do I do that.

Cheers,

JJK

Re: Network manager wifi off after suspend

pm-utils has quirks to work around these kind of problems. But how do you "manually enable your wifi"? Why can't you just automated it with a script in /usr/lib/systemd/system-sleep/ ? there is a command line tool nmcli to manipulate network manager. On a old laptop, I have made a script that unload and reload the wifi kernel module to work around similar problems.

@JJK,

If its a Dell model, the problem is likely one of the Dell-specific kernel modules. Details and a blacklisting "fix" can be found in the following thread:

Re: Network manager wifi off after suspend

Thank you for your reaction guys.

I have now set up a systemd service that runs "nmcli r wifi on" when my computer resumes.
I will post back if this has not fixed the issue.

ps.

With manually enable, I mean using the tray icon.
