If, like me, someone else has the problem of wifi not connection after suspending the pc, here's the fix.

This is the solution that works all the time in my LXLE 16.04.1. I'll paste the entire post.

16.04 runs on systemd. Try the following:

sudo systemctl restart network-manager.service

If this works, you can create a script to automate it.

Open a terminal and type the following:

sudo nano /etc/systemd/system/wifi-resume.service

Now paste the script in there with a right click:

Script:

#/etc/systemd/system/wifi-resume.service

#sudo systemctl enable wifi-resume.service

[Unit]

Description=Restart networkmanager at resume

After=suspend.target

After=hibernate.target

After=hybrid-sleep.target

[Service]

Type=oneshot

ExecStart=/bin/systemctl restart network-manager.service

[Install]

WantedBy=suspend.target

WantedBy=hibernate.target

WantedBy=hybrid-sleep.target

Exit with CTRL + X and press Y to save.

Now to activate it:

sudo systemctl enable wifi-resume.service

Hope this helps. It works on my laptop.

Here are previous solutions I tried.

Type this on the terminal:

sudo touch /etc/pm/sleep.d/wakenet.sh

sudo chmod +x /etc/pm/sleep.d/wakenet.sh

sudo pluma /etc/pm/sleep.d/wakenet.sh

and then enter the following in the created and open file:

#!/bin/bash

case "$1" in

thaw|resume)

nmcli nm sleep false

;;

*)

;;

esac

exit $?

Now save it and that's it, give it a try to check if the issue is solved.

If it did not work, just restart the network manager by typing in the terminal:
sudo service network-manager restart

And if all the above did not work, you gotta logout and login again and that will work for sure.

Where is the suspend configuration file located? I'd like to make a couple of changes on it, just to make some adjustments to better suit my personal needs.

check the help file in the accessories menu

LXLE Help? When I click on it I only get this error message:
Invalid desktop entry file: '/usr/share/applications/help.desktop'

did you remove seamonkey? if so, it takes you to the lxle wiki page...

Thank you for the info, I did remove seamonkey.

I checked LXLE's wiki page and as I type "suspend" on the search box, it finds nothing. Also tried other terms with no luck, the better I got was with "power management" but still nothing I could use came out of it.

I'm sorry but I'm still not getting there, the only thing I could find that could be related was the tlp config file which I checked from top to bottom and couldn't find it there.
I couldn't find how to customize the suspend behavior, how to change things like stopping the lock screen from appearing, not turning of network connections and stuff like that...

pemartins

But do not worry about that, I just found a workaround to make what I wanted so there's no need any more for me to edit that file.

Once again thank you very much for all your help.

I think you might be getting 'suspend' confused with the screenlocker

pemartins

Maybe, I'm not sure, I wanted to remove the screen lock after the pc resumes from the suspend state but I was able to do it with the script I posted yesterday in the first post (I edited it) of this thread; it also makes the wifi restart every time the pc resumes so the wifi issue on resume of ubuntu 16.04 also gets solved. So what matters is that it's done.

Howdy, Stranger!
