Hi all, We are using the NetworkManager version 1.8.2 on an embedded device and have done some tests with the connection check and it seems that is not working correctly.
On our system we have Ethernet and wireless working. Were Ethernet is the primary network interface. Adding the connectivity check to the NetworkManager.conf will ping a server every 10s to check internet connection. And that is done correctly through both network interfaces.

But it fails for both devices and the routing penalization function (route_metric_with_penalty) is called and updates the routing table for both interface instead of only the Ethernet one.

Thanks for any advice or help.
