No Wi-Fi

My Eachine E68 Drone 2 has Wi-Fi capability but it doesn't work. I can only use the remote control. The wi-fi doesn't appear on my phone settings, so I can't connect to it and uses the JY UFO app. (I looked for the wi-fi on my Windows 10 laptop, my Apple 7th gen iPad, my new Android phone and an old Windows phone.)
I opened up the drone but everything is soldered, the only wires are for the camera, and they were firmly plugged in.
What kind of shop would be able to check the circuit for wi-fi?
It's a fun drone but I'd like to be able to use all the features accessed by the app.
