Wifi or Dns not working after using VPN in Ubuntu
Open the following file:
sudo vi /etc/resolv.conf
Make sure the content of the file is as following:
nameserver 127.0.0.53 nameserver 188.8.131.52
We have added an additional enty
nameserver 184.108.40.206 here apart from the regular one
You dont have to reboot after this change. It will take after within seconds.
You can do this change using the following command alone:
echo "nameserver 220.127.116.11" | sudo tee -a /etc/resolv.conf
Hope this helped.
