I have been using an EAX20 Extender in a configuration with a NetGear Nighthawk EAX50 router. In general, I have been happy with the unit, and it was relatively easy to setup. My main goals were to both extend the 2.4 GHz coverage a bit deeper into the house, and also push more devices on my main floor to the 5 GHz band. I am using a configuration with "One WiFi Name", which means the extender has the same WiFi name as the EAX50 router. The only thing that was very confusing about this router, and the configuration, was the combinations of channels. I only connect the range extender with the 5 Ghz band which is on channel 149 to the EAX 50, it's 5 GHz WiFi band. However, you cannot have a DIFFERENT channel between the backhaul to the router, and the 5 GHz channel used by the extender. If I backhaul with 5 GHz, I can have a different 2.4 GHz channel than the EAX50.
