my camera need 2.4ghz connection

First, attempt to set up the camera by following the directions.  Most cameras learn the WiFi name and password by the app creating a "smart code" and pointing the camera at the screen. "Bing".

All this alarming "MUST have 2.4G WiFi" is a lot like saying, "Care WILL NOT DRIVE without engine!!!!"  Oh, **bleep**.  My car also has a radio.  I must find a way to turn off the radio or the car will not drive!  Orbi provides a 2.4G WiFi signal.  The camera should connect.

If that doesn't work, please come back and describe the specific camera (so we can look up the User Manual) and the point where the setup failed.
