Our design uses the standard 2.4GHz Wifi band. Make sure your router isn’t setup for the newer 5GHz option. In addition, LightMap displays may have trouble if your WiFi name or password contain certain characters. For example, “Kevin & Mike’s WiFi” might not work because of the apostrophe or the ampersand. As a test, try creating a simple hotspot with your phone. If everything works on the hotspot, then you know the issue is with your WiFi network name or configuration.
