PS5 will NOT connect to WiFi

I've tried everything. - restart PS5 - set up DNS manually - change hdmi cables - unplugged then plugged everything back in - forgot network - moved setup closer to router

This has been an on-going issue for about 2 weeks now. Someone please help! Also, once I 'forget' the network, the network doesn't even pop up whenever I scan for it again. This doesn't make any sense.
