My home WiFi is Verizon Fios G3100 with (2) E3200 extenders which form a whole

home mesh network which has been exceptionally stable with many dozens of different devices that I own. I've configured TapoC225 for Static IP and Tapo app shows signal strength of -35 RSSI (excellent). Generally this camera works great and I love it BUT randomly every few days it would go offline. I then tried the AutoReboot daily option but still I find many days the camera is offline.  
 

This is unacceptable for a security device I cannot trust this camera. How to fix or should I return this for a refund?

PS, I'm a software engineer with a masters degree so I understand these technologies better than most home consumers.
