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.

Install and run 64-bit Ubuntu MATE 22.04 LTS on Raspberry Pi 4

ubuntu-mate.org provide ready-to-run images for the Raspberry Pi SBC.

Here show steps to prepare on Raspberry Pi 0S 64-bit (bullseye), install 64-bit Ubuntu MATE 22.04 LTS on Raspberry Pi 4B/4G Rev 1.2 on Kingston A400 SSD 120GB SATA (using Orico HDD Adapter Kit USB3.0 adapter). For sure, you can install on Micro SD.

Enable Boot from USB for Raspberry Pi 4/400

Raspberry Pi 4, 400 and Compute Module 4 computers use an EEPROM to boot the system. If you want to boot your Raspberry Pi 4/400, the bootloader have to be updated.

Steps in my practice:

Update system using apt

$ sudo apt update
$ sudo apt full-upgrade

Run raspi-config in command line (not GUI version)

$ sudo raspi-config
> Select Advanced Options
> Select Bootloader Version
> Select Latest for the latest stable bootloader release.
> Reboot

rematk:

In my own case, I have two Raspberry Pi 4, tried to run Raspberry Pi OS 64 bit bullseys from Kingston A400 SSD 120GB SATA attached with Orico HDD Adapter Kit USB3.0.

case 1 - Raspberry Pi 4B/4G running 64 bit Raspberry Pi OS 11 (bullseye): no need doing anything, it boot from USB SSD automatically after reboot with original Micro SD removed.

case 2 - Raspberry Pi 4B/8G running 32 bit Raspberry Pi OS 10 (Buster): apt update/full-upgrade, and reboot cannot solve. Have to run raspi-config to select Bootloader Version (Latest I selected).
