Question about natelo Apple TV 4K 32GB - Refurbished (B)

Hello, I have Salt TV. My Apple TV Box does not have a Lan connection and if I switch off the wifi signal on the Salt Fibre Box, I no longer have reception on the Apple Box. I therefore assume that the signal is transmitted from the Salt box to the Apple box via wifi. I don't want wifi in the room where the TV is. Is it possible to use a natelo Apple TV (refurbished) to transmit the signal from the Salt box to the Apple box via Lan and then send the signal to the TV via HDMI? Or do I need the Apple TV Box with 128 Gb? Thanks for your answer
