After upgrading a ThinkPad X390 to Leap 15.6, the system has no internet connection. It connects to the router with both wired and wireless interfaces. The router has good internet service as shown by this machine and by booting the X390 into Windows 11.
In 15.6 wired and wireless both give this notice:
The upgrade was with a wired ethernet connection, which worked. Some information is:

What needs changing to get internet?
Thanks,

That looks as expected, although you should understand that with both wired and wireless connected concurrently, the route metric (set by NetworkManager) will mean that the ethernet path is preferred.
The DNS address is set as your router, which means your router also acting as DNS forwarder. (You could change that explicitly via NetworkManager if desired, even for test purposes.)
With respect to internet connectivity, try pinging a well-known Google DNS…

After the above, I added 1.1.1.1,1.0.0.1 to the eth1 IPv4 tab, stopped and started the connection, but there was no difference - could ping 1.1.1.1 but not google.com. It showed (after turning off wireless):

I’m puzzled what changed in the upgrade. Networking was fine in 15.5. I used the same .iso download to upgrade three other machines, and their networking is fine.

Howard
