Hi, 

I've recently upgraded to fibre broadband with Vodafone in the UK and i'm looking at removing my vodafone supplied router and switching to a new mesh system.

My question is, do i have to buy a pack of Deco routers like the BE65 3 pack, or could i start with something like the BE3600 or BE400 routers, and simply add another BE3600 later as a mash extender if needed? This seems to be the purpose of "easy mesh" but i have found it hard to get any real informtion about how this works.

Finally, I will need to use wireless backhaul for the connection between mesh access points, so if you have a recommendation about that it would be great to hear it. i'm not sure if the number of wifi bands has any benefit for this, presumably you actually need two radios? one dedicated to backhaul for best performance (I think the higher specced eero devices work this way?)

Thanks

Dicki
