networking - Wired router in front of a wireless router?

I have an AC3200, R8000 Wifi router. I want to have a wired-only router with at least 4 (preferably more) ethernet outlets in front of this at the modem and then feed the wireless router from the wired router. Can i do this simply? What should I buy as the wired-only router? (I want to move the wifi origination to a different location but don't want to move some ethernet-wired equipment where the wifi now sits or create longer wired hook-ups.)
