I have AT&T fiber internet, and the service enters through a utility closet where my AT&T router is connected. Wi-Fi works normally, but I want to connect my PS5 with an Ethernet cable. There are Ethernet-style wall ports in the living room, and I assumed they were connected to the wiring near the router, but plugging the PS5 into one does not provide internet. The apartment's maintenance staff could not explain how the wiring is set up. What should I check, and do I need additional equipment?

Simply having a jack in the wall does not mean it is active. The cable behind it might terminate in another closet, be disconnected, or have been part of an older building-wide setup. Once you locate the matching end and connect it to the router’s LAN network, the PS5 should receive a wired connection. If the router has no free LAN ports, use an unmanaged Ethernet switch.
First, find where all of the apartment’s Ethernet cables terminate. There may be a small wiring panel, closet, or bundle of loose cables somewhere. Identify the cable that runs to the living-room jack, then connect that cable to one of the router’s LAN ports. If there are several room cables, you may need an Ethernet switch: connect one switch port to the router and the remaining ports to the cables going to the rooms.
The wall jacks may not actually be connected to each other, and some older installations used similar-looking phone wiring. A cable toner and probe or an Ethernet cable tester can help you identify which cable goes to each jack. Test the living-room port, locate its matching cable, and then plug that cable into a LAN port on the AT&T router or into a switch connected to the router.
