Hi,
I have both ethernet and WIFI connection configured as autoconnect.
Further connman is configured with SingleConnectedTechnology = true.
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.
Could there be a timing issue when ethernet and WIFI come up at the same
time when SingleConnectedTechnology is enabled?
I'm using the current master (c1b9fc4) of connman.
Best regards
Tobias
