Network icon shows question mark in Ubuntu 18.04

This Question Mark means the internal connectivity test fails.

If you don’t need it, you can turn it off.


Method 1)

 Go to Settings > Privacy > Connectivity Checking 

Set it OFF. (Then, restart your WiFi connection)


Method  2)

Add a file in /etc/NetworkManager/conf.d for example 20-connectivity.conf with the following content. (You might want to check if you have other conf file with that options or if you added something in /etc/NetworkManager/NetworkManager.conf)



The empty uri disables this test.
