Hi

After moving fro EERO Pro 6E Mesh Network, The closes I found was the Deco X75 Pro V2 and if I am honest it runs fast than the EERO this is maninly down to being able to use the 6E as a backhaul.  But looking at the support pages there is no firmware upgrade list but under V1 there is and a newer version to the V2's. 

Why is this?

This is meant to be one of your fastest mesh systems but it seems the Deco X50/X55 gets more support although its slower and with the number of houses being upgrading to FFTH you would need the speed of wifi otherwise to reach the speed you are paying from your broadband would only be obtained via Ethernet.
