Behavior of LAN ports on Asus RT-N56U in Access Point mode

I currently have an Asus RT-N56U WiFi router used to serve a combination of wired and wireless devices in my house. To take advantage of some recently installed ethernet lines,I need to move the router into the basement where the newly installed ethernet cables terminate. My plan is to to install a wired router in the basement, and then configure my current wifi router into AP mode, to serve wireless clients from its current position above ground. My question is this:

In AP mode, do the LAN ports on a WiFi router still function? If not, I will need to purchase an additional switch to connect both the WiFi Access Point and wired devices to a single ethernet line connected to the wired router in the basement.

Thanks for your attention.
