What is the difference between EZ mode and AP mode when adding Wi-Fi devices?

EZ mode is the default pairing mode and requires the device indicator to blink quickly, while AP mode is the compatible mode used for dual-band networks supporting both 2.4 GHz and 5 GHz, and requires the indicator to blink slowly. In AP mode, you must connect your mobile phone to the Wi-Fi hotspot starting with 'SmartLife' before pairing. You can switch between the two modes by tapping Net Pairing Mode in the top right corner.
