That's easy to check - take eth0 down. Check the routing info. Is there still a valid gateway to your router?
Not sure if you mean "ifconfig eth0 down" , but anyway that makes wireless work suddenly.
Indeed I have both interfaces on the same router and from your explanation beginning to understand what's happening, thanks!
Yes, booting with net.ifnames=0 does the trick or instead while running the system:FWIW, I am running these dogs on an ISObooter flash drive with this menu:
