When Wi-Fi is enabled, the Wi-Fi indicator will turn on, signaling that the purifier is connected and ready for remote control via the Mi Home/Xiaomi Home APP. If Wi-Fi is disabled, the indicator will turn off, meaning the device is no longer connected to the network. This function allows you to manage network settings conveniently based on your needs, whether for privacy reasons or to troubleshoot connectivity issues.
