Public bug reported:
I have two networks:
1 x Wireless network
1 x USB dongle ( MobileBroadband)
The issue is that NetworkManager assigns the same network for both of
them so I can't do any kind of routing and basically one network is
unusable. Even worse sometimes the network is not working at all
because I guess the packets get confused on which NIC they should go.
I can provide more debug information upon request.
