I have two TP Link Archer C4000 (AC4000) routers.  The second one is set up as an Access Point and is connected to the main router via an ethernet cable.  The main router handles the DHCP, which is turned off on the Access Point.  The main router and the access point both have reserved IP Addresses.  I can connect to the Access Point using its IP Address, via a laptop and ethernet cable, but that is a real pain to do- have to pull my laptop out, and the router is eight feet off the ground.

Why can't I connect to this Access Point using its IP Address via WiFi?  What am I missing here?

Thanks in advance,
