Unidentified Network Following Router Swap

[VC91]

I have a home office for my IT company and following my cable router needing swaping due to failure, when I connect my laptop (same way as always) to my Kensington USB3.0 Dock I get TWO active networks (I have disabled wireless to rule that out) 1. The actual network name showing as Private and 2. Unidentified Network showing as Public.

I have tried with and without my firewall app running. I have rebooted every connected device including the dock. I have also run "DisplayLink USB Graphics Software for Windows 8.2 M3" to upgrade my software - I assume this includes an updated network driver - Just checked NW properties and it shows as Displaylink Ehernet Driver version 8.2.1629.0

I am running up to date Windows 10.

The unidentified NW has only appeared since the new router and only shows when I am connected to my Dock.

Any ideas on why this has happened and how I can remove the Unidentified Network?

Many thanks,
Paul.

Did you try to use only one router?
