[Bug 1450652] [NEW] 15.04: no route when connected to both WiFi and Ethernet
Public bug reported:
Steps to reproduce
===============
1) Enable both a WiFi connection and plug into Ethernet
2) Test your network connectivity or run `route`
Expected results
=============
NetworkManager should prefer the wired connection over the WiFi
connection, and `route` should return something like this:
$ route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
default 10.17.75.1 0.0.0.0 UG 1024 0 0 wlan0
10.17.75.0 * 255.255.255.0 U 0 0 0 wlan0
link-local * 255.255.0.0 U 1000 0 0 wlan0
(To get the above results on Vivid, I had to unplug my Ethernet.)
Actual results
===========
`route` will produce no results and your connectivity will be broken
Work-arounds
===========
As soon as you disable either the WiFi or unplug from Ethernet, you will
again have a route and your network connectivity will work. This is a
regression from Trusty and Utopic.
