There can only be one 'eno2' network interface and that is handled by 
the kernel and udev.

What you are seeing is two Network Manager "connections" (as in 
configurations) one with 'connection.interface-name: eno2' and one with 
'connection.interface-name: --'.

This could be the source of your problems. My suggestion would be to 
delete both connections, and create a new one from scratch.

You might want to use some other name for it than 'eno2', e.g. something 
like 'wired' or 'home'.

This will prevent any confusion with the interface name (what if it 
changes?) and it's also easier to distinguish between different 
configurations, e.g. in case you ever need to have a 'work' connection 
or so with different settings.

Hope this helps,
