[Workaround] How to fix connection bug within NetworkManager 1.22.2

Hello. If you have some connection troubles with NetworkManager 1.22.2, it is a known issue.

To fix it - until a new major version is released - you have to modify /etc/NetworkManager/NetworkManager.conf add this:

[main]
dhcp=dhcpcd

After this, a little service restart: sudo systemctl restart NetworkManager
