1. Using an android device, if the user cannot set the WiFi hub because the App cannot find the WiFi Hub, go to the phone settings, application permissions and enable all the permissions required by K-Rain Pro EX WiFi App. This will enable the smartphone to find the WiFi Hub when the blue light is flashing and it is broadcasting in Hotspot AP mode (ready to connect).
2. If a user still cannot find the WiFi Hub, make sure the GPS Location is enabled. Go to the device settings, connections, location, turn on to enable the GPS Location feature.
