First of all will your broadband be FTTC and delivered by copper from the cabinet or will it be FTTP, fibre delivered. If the latter, then you will have an ONT which is an optical modem which you can connect your Google mesh to directly without using a Home Hub. If you will be getting FTTC, the Home hub can't be used in modem only mode. You can turn off the wifi but it will still be routing and natting. You could always buy a stand alone modem rather than use the hub. How are you connecting at the moment in your current house?
Thanks for your reply.
It is FTTP so sounds like I can just connect the mesh to that.
Will this work with the bt tv if I run an Ethernet from the google mesh to the tv box?
It will not work, as it cannot carry the multicast data. It looks like you may have to return the product and use something else instead. You may have to use the BT home hub, and a couple of BT Mini Connectors (discounted cost for BT YouView customers).
Googling seems to give conflicting information regarding multicast capability, its a serious omission for a router not to support it these days. I guess the fallback position if it doesn't, is to just turn off wifi on the hub and use that in conjunction with the Google whole home.
Thanks for this. So if the tv won’t work without the bt hub. Will it work if I turn off the WiFi on the router and use google for the WiFi network but then use the mini connectors (connected to the bt hub) for the tv?
Yes, I cannot see any reason why it should not work, as I think others do it that way, but using the BT Whole Home wifi as their wireless mesh. Not sure whether all of the features of the Google unit will work, as some rely on having a direct connection to a WAN.
Have you checked to see whether the Google system can be used with an existing router?
Remember to ask for the mini connectors (£20 discounted).
As long as the hub is on a different channel to the mesh there shouldn't be a problem using both. The hub can only use channels 1,6 and 11 on the 2.4Ghz band and 36,40,44 and 48 on the 5Ghz band, split the bands on the hub and set the channels manually as far as possible from the whole home channels.
