@deak Facing the same issue with the two cameras of Tapo C510W. Suprisingly, the cameras and the router were on same spot since the installation and were working well until few days back. 

Tried all the troubleshooting methords, including splitting 2.4 and 5Ghz bands on the router.

I noticed something interesting: when motion tracking is on, or if I manually move the camera direction, it starts having the network connectivity issues I mentioned in the original post. But if I turn off motion tracking, the camera works fine without any connectivity issues, just like before. I've left it running without motion tracking for the past several days and haven’t faced any network issues, but as soon as I switch motion tracking back on, the problem starts up again. So, it seems like there’s definitely an issue with the camera itself related to motion tracking and movement. So in short, what appears to be the issue is that after couple of months of using it with motion tracking, the camera seems to have developed some issues where motion tracking or manual direction movments starts causing network connectivity issues. I hope this gives you enough info to help debug the issue and release a firmware fix, so I can get back to using the camera with motion tracking—since that’s the main feature that sets it apart from fixed cameras.
