So I just moved into a building that forces me to use a certain ISP. Turns out they have an ONT in the building and the only thing I have access to is a managed switch in the wall of my closet that then has cables running to ethernet ports in my walls but they only activated one port and want to charge me for activating others. They set me up with an Eero Pro for wifi that I want to get rid of, which is plugged into my only working ethernet port in the wall, and then my pc is plugged into that while everything else I have is using wifi. I have a NAS I need to plug in though so I was thinking I could either get a new switch and plug that into my one working wall port then a wireless access point or should I just get a router? I've always had modem and router combos from my previous isp's and I never really got into networking enough to know when to use switch/access point or router and I've never had to deal with this ONT setup before, feeling a bit lost. It's just a 1 bedroom apartment so don't need any crazy range, and I'm just connecting my pc and nas wired and tv, laptop, and cell phone wirelessly.
