+++ This bug was initially created as a clone of Bug #244149 +++

When you create a new DSL/PPPoE connection, it doesn't appear anywhere in the list of available connections. I'd expect a new category to appear in the left column (Interfaces) but all I have is my regular Network Interface, the WLAN Interface and the Virtual Private Network. In the right column (Connections) I also only see the currently connected WiFi and my VPNs.  Show More doesn't display it either.

It is in the config file though:
