Ubuntu - DNS not automatically configured. Has to be set manually in /etc/resolv.conf
When I connect to a network (e.g. home or work network), I have to manually enter the nameserver adresses in /etc/resolv.conf every time (I change to a new network). It used to be automatic. Any ideas how to change this back to automatic again ?
