Ps5 won’t connect to WiFi

My Ps5 in the network settings connects to my Ethernet cable no problem. But whenever I try to load into multiplayer games it says I cannot connect to the PlayStation network. On some games when I try to load up it tells me I need to buy play station plus. When I try to go into the PlayStation store it says something went wrong and to try again later as well and in the PlayStation plus app. I have restarted my router multiple times tried not using the Ethernet and many other things. I gave up and went to bed and woke up and the same issue is occurring.
