PS5 won’t connect to the internet. I have tried everything.

So far I have tried:
Turning it off and on again
Restarting it
Enabling/ disabling WiFi/ internet connection
Using LAN
Using a different WiFi network
Forgetting and trying the LAN/Wifi again
Enabling/ disabling console sharing
Changing the DNS
Renewing my game licenses
Unplugging it
Unplugging it alongside the router and modem

It started with just random disconnection and reconnection, but now it will not reconnect at all

Everytime I try something and I get a pop up telling me what might be wrong it’s something different.

I also bought it used and it’s a bit older, If that makes a difference.
