My WiFi connection regularly does not work after suspending Ubuntu 20.04. I had a similar problem with Ubuntu 18.04 but then I could always run

sudo service network-manager restart

and it would work again. However this does not work anymore since I've installed Ubuntu 20.04. I followed the wireless network troubleshooter guide on the ubuntu website. I tried to connect to a different network (phone hotspot) and I tried some of the the opposed solutions I could find in related questions like

sudo nmcli radio wifi off

and

sudo mncli radio wifi on

or

sudo systemctl enable wifi-resume.service

Nothing works so far. The problem occurs about half the time I suspend my laptop or close and open the lid. The only solution I have now is to reboot or suspend and unsuspend ubuntu again.

Any thoughts on possible solutions here?
