Why does my laptop always to to Wifi 4 [closed]

        I am using Asus ROG laptop with Intel AX200 network card as below.

I have a router with Wifi 4/5 enable. My phone (Android 10, Redmi) can connect to Wifi 5 without any problem. However, my laptop always go to Wifi 4.

I already set the Preferred Band in Device Manager -> Network Devices as below.

Anyone can suggest me a fix? I am using Windows 10.

Many thanks
