Suspicious car hacked my camera Home base

A suspicious car parked in my driveway 3 minutes later my cameras stopped working and my camera home base started flashing like it couldn’t connect to the network. My internet was still working fine that never happened before any advice on how to secure it?

Similar issue, a dog entered my property, cameras all went off line (base station), then something killed my chickens and left them

Aosu has never came up with an answer as to why this happens. They want to blame my wifi but my wifi was working fine.
