I'm using a desktop with a wired connection (Ubuntu 20.04.1 LTS). I keep getting DNS_PROBE_FINISHED_NO_INTERNET (on chrome and other browsers). Running: "sudo service network-manager restart" in terminal solves the issue for a few minutes. I need a permanent solution...
Edit#1: I haven't installed any firewall. Firewall: ufw status
