Ring Video Doorbell 2 intermittent connectivity

Are the  Home Wifi Plugs  Virgin's WiFi pods ?  If so then according to the FAQ's on the  https://www.virginmedia.com/help/how-to/broadband/wifi-pods  page for both the black and white WiFi pods 

Ring doorbell
For some reason, Ring doorbells can occasionally – and unfortunately – disconnect themselves. When this happens with your doorbell, you’ll need to reset them manually in order to reconnect them to your WiFi

It might be an idea to go into the hub 5 settings and temporarily disable the 5 GHz connection so the ring device connects on the 2.4GHz band.   To do this go to Advanced Settings > Wireless > Wireless Signal,  click on Disable Channel Optimization and then click on Disable the 5 GHz band and then on Save changes.   

Once the Ring device hopefully reconnects you will then need to go back into the same settings and re-enable the 5 GHz band and the re -enable Channel Optimization and Save the changes again or your WiFi pod(s) won't work.

Thanks - tried that and again it connects briefly after reboot but then struggles to reconnect. I have messaged Ring for support … 

As above I have reset the Ring Doorbell 2 and it made no difference. I have found an old tp-link 2.4ghz router and plugged that into my main router - I then changed networks on the Ring doorbell to the 2.4ghz router and it connects fine... back to the way it was.

But this isn't sustainable - I don't want to run two routers, and besides the RSSI is now red (RSSI -79) between Ring doorbell and the old router.

WHY has this stopped working this week? Has either VM changed something their side, or Ring has changed something on theirs that now is causing problems with Virgin Media Hub 5 combined channel optimization / wireless signal ??

If something is stopped being supported then we should have notice...
