1. The fountain, Wi-Fi router, and the smartphone are too far from each other during the process of set-up. Please make sure they are at a distance of 1-2 meter from each other.
2. You Wi-Fi is dual-band of 2.4G/5G. Currently, our fountain only works with 2.4G. You can select the frequency of 2.4G only. Please read the Wi-Fi router’s manual for configuration.
