Fixed: Raspberry Pi OS cannot find 5G Hz WiFi Network

Recently, when I tried 64 bit Raspberry Pi OS (Bullseye) on Raspberry Pi 4B/4G, it's found 5G Hz WiFi Networks cannot be discovered, and connected.

To fix it, I set set WiFi Country to US.

MENU > Preferences > Raspberry Pi Configuration
> select Localisation tab
> Set WiFi Country...
> Select US United States

remark:
I have another Raspberry Pi 4B/8G running 32 bit Raspberry Pi OS (Buster), no this problem.
