  1. From the comments...

    There was no ethernet cabled plugged in, yet Network-Manager kept creating new Wired Connection profiles. It shouldn't have. Depending on your specific ethernet hardware characteristics, it may have thought a cable was connected, and repeatedly tried to make a connection.

    We set the Wired Connection not to connect automatically, and deleted the other Wired Connect 2/3/4/etc profiles.

  2. I found a permanent fix for this problem:

    1. Add these lines to `NetworkManager.conf

      [keyfile]

unmanaged-devices=interface-name:enp0s26u1u4

    2. In the edit connection dialogue box put just interface name as device
