Just purchased a used Theta M15, I can’t get WiFi to connect. In using the 8 digits on the bottom, I tried the reset button on the bottom, and I tried different phones. WiFi light is on and solid red.
Make sure your mobile phone is using 2.4GHz for the connection. Power cycle your camera by pressing and holding the power button. Put your mobile phone right next to the THETA. Verify the camera is not connected to a different mobile phone. See other ideas for troubleshooting below.
I suspect this camera was a special event or use camera that has a different wifi password. The camera says NBCUniversal on it
