The Ubuntu 17.04 distribution is not connecting to Internet, not in a live USB session, nor after the install. I've got a Dell Inspiron 24-7459. This is a major issue as I cannot update or download anything. Without the possibility of connecting to the Internet I'm completely stuck.
I've followed the instructions on this thread and nothing changes:
In my case it's not a question of WIFI only. The Internet is not working even under the wired connection.
