Input Settings

[Akajak]

First post, Apols if I'm in the wrong section.

I have sky q and a mini box

my broadband is provided by BT

sky has provided me with a Wi-Fi booster.

when I go to settings section on my tv and it asks for my WiFi settings should I input the BT Wi-Fi settings or the sky booster ? 
hope that makes sense, Tia

Edited to add I'm calling it a sky booster; white box with green lights on front sitting near my bt router
