I have recently bought tp link TAPO , I am unable to connect to wifi unless its in direct sight, even though all my devices are having full rage on 2 ghz network, Even if the device is right below my wifi , separated just by a plank on which my wifi resides. Am not sure if its a defective device or expected function.

My device details are as follows:

TP-LINK Tapo Wi-Fi Pan/Tilt Smart Security Camera, Indoor CCTV, 360° Rotational Views, Works with Alexa,Google, No Hub Required, 1080p, 2-Way Audio, Night Vision, SD Storage, Device Sharing(Tapo C200) | B07XLML2YS ( B07XLML2YS ) HSN:85258090
