My wi-fi keeps disconnecting

[AC Question]

This morning I received a message that my wi-first was being hacked in big bold red letters. It asked if I wanted to disconnect, I did. Now it reconnects and disconnects immediately. My tablet and laptop connect and stay connected. I reset the WiFi and bluetooth, but the same problem continues. How do I fix this?
