I have configured and tested the camera, using a spare Asus wireless router. I'm setting this up for a friend who has no internet connection, and I have set it up using his Android phone. There's a 512Gb Sandisk Extreme Pro SD card installed in the camera

I thought that after removing the WAN feed (internet source), to simulate the router now being at his house, that the camera and Android phone would communicate with each other via the Asus router?

But this is not so!

Question - how do I need to setup the Asus router so he can still access the camera with the Tapo app on his phone? As an Access Point, or disabling DHCP, or what?

I'm familiar with setting up an Asus router for normal use, but I've spent a few days on this issue with no success.

Any ideas anyone?
