no, my building uses unity as their isp, with them i get wifi for the apartment which is completely separate from my direct connection so technically i have 2 different internets, I dont need nor have any routers, modems or anything like that to run the internet. My direct connection that i use for my ps5 (the one i plugged the r2 in with) is a cat 5 outlet in my wall so i plug from there directly into the ps5.
