[SML] Linux networking help needed

[Jerry Durand]

This is strange...

Yesterday I was setting up a WiFi access point and plugged its Ethernet
into this Linux box (Kubuntu 18.04).  In setting it up I accidentally
deleted the connection, but that shouldn't be a problem, plug in my
network and it should pop back.

Only it didn't, Network Manager shows Bluetooth but no wired
connections.  But, the task bar icon changes from red to white and blue
when I plug the cable in.  WTF.

Doing a lot of searching I found my interface name apparently changed
from eth1 to eno1.  Well, strange but ok.  I fixed the /etc/interfaces
file and from the command line got reconnected.  I'm plugged into our
office router and that's working.  Small cheer!

Hold the beer!

The Network Manager still shows no Wired networks connected BUT there's
one in the main list.  Remember I'm currently connected and posting
through it.





Any thoughts?  Web searches turn up similar problems but I haven't
gotten the manager working yet.
