[Bug 1569484] Re: Auto Ethernet connection profile appears. Wifi does not work anymore.


I've had the same problem on the same laptop (Dell XPS 13 9350) with Ubuntu Gnome 16.04.
I've had this since I've started using the networkmanager-openvpn and networkmanager-vpnc plugins in order to be able to connect to a VPN service. Also, since I've been using Xenial since the beta release (and thus having "passed through" all of the kernel updates) I do not think that this is a kernel issue but rather a NetworkManager one (or the VPN plugins).

I've managed to overcome the issue like this:

Whenever my wifi was recognised as wired if I restarted the network-
manager service with

sudo service network-manager restart

wifi was back again.

In order to automate this and not do it every time after login I've
simply added the above command on


Now everything works fine...until an official fix is issued (...again
IMHO a NetworkManager issue).

I hope that this will work for you as well.
