@Bayaz Hello, 

Thank you for your feedback,  you could try some suggestions here for camera offline issue:

1. Confirm Camera firmware and Tapo APP version are up-to-date 

2. Try to change Router's DNS setting to 8.8.8.8

3. (For test purpose) Turn off Router / Modem firewall settings

Turn off router Advanced Settings on like Firewall settings / Parental control /QoS etc.  

4. Make sure camera is connected to router directly not through AP or Range extender 

If the above does not work, please help provide some details and help collect the log when issue after issue happened, thank you. 

1. Would the system LED on the camera turn Red or stay Green when it is offline

when mobile phone is still connected to home network ( home wifi, not mobile data) does camera become offline on Tapo app? 

2 What is the model number of Wi-Fi router?

3. Check camera signal strength (RSSI: Received signal strength indication): On the APP, go to device  settings->click the name of the device -> tap on the Wi-Fi icon to see the RSSI value

4. How to get the logs of Tapo camera
Step 1: Insert an SD card into the camera.

Step 2: On the APP, please go to Camera Settings -> Advanced Settings -> enable Diagnose. The log file will be stored on the SD card.
Step 3: Let the camera run for some time, wait for the recurrence of the problem.
Step 4: Please plug the SD card into the computer's SD card slot or an SD card adapter. Please send the log on the SD card to us. The name of the file is ‘Diagnose Log’.
