Hi,

I've got 5 Deco M4s, all in AP mode as using ISP router. I've been with Sky in the UK and Wired Backhaul has been fine. I've since changed to Virgin so have a new router and now Wired Backhaul is not working, it keeps showing WiFi is being used. WiFi is disabled on the ISP routers.

What's weird is I have seen on the Forums that the Virgin router does not support IEEE 1905.1. But the only thing plugged into the router is a TP-Link switch, to which the Deco's are connected, either directly or via other TP-Link switches.

I don't understand why or how it's not working with the Virgin router in play because the Deco's shouldn't care in my layout. If I switch back to the Sky router, Wired Backhaul is fine again - I am not changing where anything else is connected - literally just swapping between ISP routers. The main Deco is directly connected to the "main" switch.

Thanks for any help provided :)
