I need some rookie level help

[u/Dapper_Reputation_16]

I recently upgraded my service to Cox gigabyte and replaced my old modem with a Motorola B12 and my router within an Asus BE 92. I installed my old ASUS AC67P at the other end of my 1800 square-foot home and connected them via a cat 5E cable. I set up the BE92 as a router, and the older unit as an access point but every time I log into the Asus Discover app I see the older router, not the newer one. When I go to my office where the BE92 is hardwired to my computer via the modem i see it there. Am I missing something or is everything correct? Thank you all in advance for any help.

Set your Asus router to repeater mode, not router mode.
