Hello @MogaRaghu 

If camera used to work fine before, please reboot camera first. 

Can you help collect the log of camera, so we could look into the issue further. 

How to Get the Log of Tapo Camera?

May I know the model of router and extender,  and your network map?  Were you able to access the camera remotely through the extender?  

Hello @MogaRaghu  

Thank you very much also for providing the log, yes, we can see that there are different cases about camera remote control issues, but some of them are solved by trying different troubleshooting steps, in further troubleshooting some are approved to be related to firewalls, DNS settings or some other factors. So far none of them has been considered  as a known issue. 

We appreciated your time for collect log, unfortunately the log file is pretty short we could not find useful information.   If you got some extra time, you could reboot camera, wait camera to boots up completely stable on, then enable Diagnostic and collect the log at least for 5mins when camera is running.  I will also create a support ticket for you to follow up your case through email, please check your inbox later.

-67dBm is still acceptable, signal strength lower than -68dBm may cause poor experience and that is pretty close. 

If reminds me that if your extender use the same SSID with router, camera may roam between router and extender, and go offline sometimes especially when signal is not that strong. If possible, please put camera closer.
