At present, the VPN between routers 1 and 2 go via the HUB 3.0 (both outside interfaces addresses are assigned via the Hub DHCP service) so the VPN termination addresses are single NATd by the Hub. At present everything wired works perfectly.
The crux of my problem is I'd like to disable the Wi-Fi as channels 1, 6 and 11 are all in use.
I could -
Change the channel on my Hub manually to the same as one of the neighbours (not very neighbourly when traffic increases)
Change the channel on my Hub to the same as one of my active networks ( a bit annoying )
Channel utilisation at present would easily cope in either situation, but one neighbour's VM router likes the idea of picking an overlapping channel which then increases the noise and pushed the non-802.11 interference observed quite high.
When I had a BT router I just switched Wi-Fi off and everything was tickety-boo - which is why I'd like to just do the same now.
When I signed up for VM I asked if I could just switch off the wireless on the Hub and I was told yes. I did not follow the question up with "will that stop me from using any of the four wired interfaces ?"
