The NAS is hardwired via the VM router
However I have fixed it (almost)
the MESH wifi was not in bridge mode - which I ahve now done - so only the VM router is running DHCP
Unfortunately I lose the mesh "Guest wifi" as that is switched off when in bridge mode - but I can run that from the VM box and most people I would give the "Guest" to I would happily give the main wifi password to
However the Printer still wont connect so i have to run the VM to give wifi to the printer (but switched off the ssid broadcast)
So I now have a mesh system that gives me a good speed c70 MBps in the living room and 35Mbpsin the far bedroom (compared to 20 & 0 - although 20 ish with a powerline adaptor)
Oh yes and I can now access the NAS from the laptop so the backups are now taking place
