TpLink EAP 225 not showing up on router

[aaronac8]

I have a TpLink EAP 225 AP that works but I am unable to find it's ip address. I look on my routers DHCP clients list (have DD-WRT on my router) and do NOT see my EAPs MAC address. I can only log in to the EAP wirelessly via a web browser with address tplinkeap.net. My EAP is connected directly to my router via Ethernet cable.

Any suggestions on how I can find out my EAP's IP?
