Can't see Wi-Fi settings in Ubuntu 20.04 LTS

Ask Ubuntu Asked by NOVA1323 on December 27, 2021

I am new to Ubuntu and until yesterday all was working fine but when I booted Ubuntu today I can’t see the WiFi options in my tray or in the settings.

enter image description here

I have tried restarting the network manager using
sudo network-manager restart
but there isn’t any change.

I also tried
lshw -c network
and I get the following results

Also running

gives me this error

So after contacting Dell a service engineer came to visit me and the problem seems to be a broken antenna cable (this seems to be a common problem with Intel Killer WiFi cards) which connects to the WiFi card. Replacing this would fix the problem in my case.

Thanks for the Help.

I got the same issue today when I turned on my PC. My WiFi driver was unavailable in the ‘Additional drivers’ section of ‘Software & Updates’. I tried and checked if this would fix with restarting the PC. But it didn’t.

So, I connected my PC through wired connection and updated Ubuntu through ‘Software Updater’. After that I restarted my PC and now it is working fine.
