I change my wifi router, so I do factory setting on my smart AC control. However, I cannot able to connect my AC control to my wifi after trying a lot of times. My wifi works well with all my other device like iPhone, computer, Apple TV,,. but not the AC control.

The error start at the accessory setup (which should be using airport function). My wifi is for sure 2.4GHz. Below is the picture of process. Please advise how to solve below problem.
