Access points lose SSID

Came home today and see all of my devics are connected to 1 access point. I have 4. It seems No SSID’s are assigned to 3 of the access points. I didnt make any changes. How could this happen? How can I get them back?

So I deleted and re added the WiFi networks. Now it is not showing a 2GHz and 5GHz network on all WAPs. Only the equipment closet is showing 2.4 and 5. Any ideas?

Your site appears to be experiencing heavy interference on the 2.4GHz band. Is it possible to reduce that?

not sure what would be causing the interference

Check the scans available in the Info tab of your AP configurations.
