Public bug reported:
NetworkManager poorly handles multiple connection setups, making it more
an annoyance than a tool.
With multiple connection setups, instead of switching connectivity to
whichever network is available, NetworkManager seems to collect problems
from all sources and blocks networking as soon as any one of the
connections has a problem.
My setup contains a wired and a wireless connection, here's what happened:
a) Both wired and wireless work properly: Networking works
b) Wired network is disconnected, but wireless is working fine: Cannot connect
anywhere, destination unreachable
c) Wired connection works fine, but wireless is turned off: Cannot connect
anywhere, destination unreachable
What I expected to happen:
a) Both wired and wireless work properly: Networking works
b) Wired network is disconnected, but wireless is working fine: Networking works
c) Wired connection works fine, but wireless is turned off: Networking works
I ended up having to remove the wireless adapter from my computer just
to avoid everything breaking down twice as often as it usually would.
