My PS5 originally started disconnecting and reconnecting at random, but now it cannot get back online at all. I've restarted the console, toggled Wi‑Fi settings, tried a wired LAN connection, tested another Wi‑Fi network, forgotten and re-added the connections, changed the DNS, renewed licenses, unplugged the PS5, and power-cycled it along with the router and modem. The error message seems to suggest a different cause each time. It's an older PS5 that I bought used, so I'm wondering whether this could be a hardware problem.

This could be a failing Wi‑Fi network card. Someone I know had the same pattern—random disconnects at first, followed by the console refusing to reconnect—and the wireless hardware in the PS5 had died. Testing it on a phone hotspot and with Ethernet should help confirm whether the problem is the console or your home network.
First check whether other devices on the same network are having trouble. If everything else works normally, connect the PS5 to a phone’s mobile hotspot for a while. If it still drops connection there, that points away from the router and toward the console itself. You can also continuously ping the PS5’s local IP address from another device to see whether it disappears from the network when the error occurs.
