I have a 4g+ home wifi network wit 3 Deco E4R wifi repeaters. The installation is at a summer house far from my home address.

 It seems that all 3 solar cameras (1 410C and 2 425C)  disconnect and appear offline. 2 other wifi camers  C520WS keep working without  disconnecting. The problems  automatically  solves when I connect my phone to the same wifi network. 

Do you suggest any solutions?
