My Wifi network won’t show up

Hi- I live in a building, and everyone’s wifi networks show up except for mine. I have even tried to make a hotspot and that doesn’t show up either.

I just got my Tidbyt today so this is really frustrating. It’s connected via Bluetooth, but my wifi network doesn’t even show up for me to have an option of joining it

make sure it’s a 2.4ghz network.
