The computer can't be detected by my phone to use Miracast

Problem

When Miracast is used to project a phone screen to the computer, the phone cannot detect the computer.

Miracast helps to project a phone screen to a computer screen.

Cause

When Miracast is used to project a phone screen to a computer screen, Windows 10 will automatically select a 2.4 GHz or 5 GHz WLAN channel based on the current environment. Single-band phones support only 2.4 GHz WLAN channels, while dual-band phones support both 2.4 GHz and 5 GHz WLAN channels.

If you are using a single-band phone and the 5 GHz WLAN channel is selected, the computer cannot be detected.

It is recommended that you use a dual-band phone and a computer for wireless projection using Miracast.
