Need a new setup

Currently my ISP is spectrum at 400mbps and I have a Google mesh network set up. I have arlo camera connected to the Google router. On a daily basis google loses connection and goes out for about 45sec-1min. I wanted to separate my router from my wifi access point. I was looking into tp link and have seen some videos, but I'm wondering. Do I have to have the controller, router, and switch to do this kind of setup or can I run it with just controller and router and wifi access point.
