WNCE4004 will not connect with AC1750 router despite multiple attempts

I purchased a Archer C7 AC 1750 router and cannot get my WNCE4004 wireless HD video and gaming adapter to connect to the router. I tried using the set up wizard and also WPS and when I use the wiziard I get the following message: "Please move device closer to your existing router or gateway. The selected network is no long available. Please make sure the existing network equipment is within the proximity of the extender". I had the adapter about 3 ft away and got this message. All my other wireless non-Netgear adapters and wireless bridges, PC, printer, and laptops connected to the router with no problem. I have tried to set up the adapter using 2 different computers and also tied to reset the Netgear adapter. Nothing has worked. Any recommendations would be appreciated.
