Hi,

The use of SingleConnectedTechnology should be avoided if possible. It
just works too strongly and disconnects the other service even if
someone is using the connection.
Have you tried just to set PreferredTechnologies=ethernet? At least
that setting works in my laptop and only ethernet is normally
connected. I can still manually connect other wifi services and the
ethernet connection would not be disconnected in this case (because I
have SingleConnectedTechnology=false in my conf file).
Just tried that and it ends up with ethernet and wifi configured with
the default route set on the ethernet. This may happen because
connecting to the wifi here is in most cases much faster than connecting
to the ethernet (both DHCP). But I think I can live with that.
Today after boot the ethernet connection was setup with a correct IP address
(DHCP) but a missing default route. After a restart of connman it was ok
again. I wasn't able to reproduce this behaviour a second time by rebooting
or restarting connman.
I have not really seen this behaviour.
On my machine this was just a one time issue. I couldn't reproduce this
a second time so far.
Could there be a timing issue when ethernet and WIFI come up at the same
time when SingleConnectedTechnology is enabled?
Are your ethernet and wifi in the same subnet i.e., are they both in
192.168.0.0/16? If so, that might explain this behaviour.
Ethernet is on 192.168.0.0/16, wifi is on 10.0.201.0/24. Looking at the
logs setting up ethernet and wifi seem to be intermingled and wifi
minimal faster in this case.
I'm using the current master (c1b9fc4) of connman.
