PS5 won't connect to wifi with full bars and other devices connected.

The past couple days my ps5 will not connect to the Wi-Fi router. When searching for networks my Wi-Fi shows full bars and when I try to connect to it, it says it can't and that the signal is too weak. It is maybe 6 feet away from the router and connected to it before. Other devices can connect to the router with no issues. I have forgotten the network and tried to reconnect it that way (did not work). I have restarted my PS5 (did not work). I have restarted the router, it connected for like 30 seconds, then disconnected and wouldn't reconnect. I've tried entering my DNS manually and nothing is letting me connect/ stay connected. I was able to connect it with a LAN but I don't want a cord run across the room for constantly. Any fixes/ suggestions? And yes I have made sure my PS5 was up to date. I should also mention that I was able to connect my PS5 to my mobile hotspot so I believe the issue lies with the modem somehow.
