Hello   @BuBaBa 

If tapo camera keep going offline, please try some tips here like double check the Router Advanced Wireless settings and ensure camera received strong wifi signal of router. 

What should I do if my Tapo smart camera keeps losing connection or going Offline?

If still the same, can you help provide some case details here: 

1. When the issue occurs, does the smart device work in the local network?

For a test, connect your mobile device to the home Wi-Fi network at that time and see if the Tapo device is still accessible in the local network?

2. the model number Wi-Fi router and your network topology:

e.g. ISP Spectrum-Archer C7 router<Wireless> tapo device

3. Enable Diagnose mode, get the log of the camera, and share the log file.

How to Get the Log of Tapo Camera?
