Please open a terminal and do:

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

Use nano or kate or leafpad if you don't have the text editor gedit. A new empty file will open. Add the following:

[Unit]
Description=Local system resume actions
After=suspend.target

[Service]
Type=oneshot
ExecStart=/bin/systemctl restart network-manager.service

[Install]
WantedBy=suspend.target

Proofread carefully twice, save and close the text editor. Now do:

sudo chmod +x  /etc/systemd/system/wifi-resume.service

And next:

sudo systemctl enable wifi-resume.service

Reboot and let us know if the problem is solved.

Does this depend on systemd | upstart? – Pilot6 Mar 03 '16 at 14:37
I am asking because I have this problem too, but I have 14.04 with upstart. – Pilot6 Mar 03 '16 at 14:43

This is the systemd method. – chili555 Mar 03 '16 at 20:41

Worked for me on 16.04. Anyway, before applying this new service, it is advisable to first run /bin/systemctl restart network-manager.service natively in the shell and see if it helps. If not, this extra service does neither. – Tik0 Jan 19 '18 at 07:06

This did not work for me on 18.04. – Russell Richie Jun 19 '18 at 20:21

@RussellRichie I suggest that you start your own new question. – chili555 Jun 19 '18 at 20:30
