Overview

Introduction

Intel Wi-Fi 6E wireless NIC adopts Intel's sixth-generation wireless protocol AX standard, which enhances performance and compatibility compared to the previous generation 802.11AC protocol, while reducing power consumption and increasing service life.

Feature

  • Adopts sixth-generation 802.11AX Wi-Fi standard, provides better performance and compatibility than the previous generation 802.11AC, lower power consumption, and longer service life.
  • Supports 2.4G/5G/6GHz tri-band, the speed up to 574Mbps in the 2.4GHz band and 2400Mbps in the 5GHz/6GHz band.
  • Support Bluetooth 5.3 standard, longer transmission distance, and better stability. (BLE5.2 for 002 version)
  • Adopts NGFF (M.2 A/E Key) interface.
  • Adopts the new generation of MU-MIMO wireless technology, provides better network quality, faster Internet speed (more than three times), and higher transmission and download efficiency.
  • Support Linux, Windows 10/11, etc.

Notes

  1. In the Linux environment, you need to use a kernel of no less than 5.11 to work normally. If you only need WIFI without Bluetooth, the 5.10 kernel can also work.
  2. The native system of Raspberry Pi CM4 cannot work, and the kernel needs to be recompiled.
  3. The default hardware version for AX210 is 006,The hardware version of AX210 before 20230919 is 002
  4. Connection method: The connection method of WIFI is PCIe, and the connection method of Bluetooth is USB.

Compile Kernel

You can refer to here.
Ubuntu system is required for kernel compilation.
Test by the following command: Ubuntu-20.04.2.0-desktop-amd64 ：
Confirm the specific Raspberry Pi system version you need before compiling the environment: https://github.com/raspberrypi/linux

On the Raspberry Pi:

sudo su

sudo reboot

On the Ubuntu:

sudo sshfs [email protected]:/ /mnt/pi-ext4
sudo sshfs [email protected]:/boot /mnt/pi-fat32
#192.168.x.x is the IP of the Raspberry Pi

sudo cp arch/arm64/boot/dts/overlays/README /mnt/pi-fat32/overlays/

If an IP is connected multiple times and the system is changed, a read: Connection reset by peer error occurs:
Just delete the ssh public key authentication.

ssh-keygen -f "/root/.ssh/known_hosts" -R 192.168.x.x
  #192.168.x.x is the IP of Raspberry Pi

Install Driver

The kernel compiled above uses "ARCH=arm64" 64-bit.

Add in /boot/config.txt of Raspberry Pi
arm_64bit=1 kernel=kernel8.img
#reboot
sudo reboot

The module needs to add an antenna to have a signal, please pay attention to adding an antenna before use.

WiFi

Since the "intel wireless wifi MVM" driver supports many WIFIs, it is not limited to AX210 or AX200. If the kernel is compiled with "intel wireless wifi MVM" enabled, and arm_64bit=1 kernel=kernel8.img is added to /boot/config.txt, and then restarted, then check whether the log will appear as follows: 

dmesg | grep iwlwifi
[    4.574560] iwlwifi 0000:01:00.0: enabling device (0000 -> 0002)
.....................
[    4.586465] iwlwifi 0000:01:00.0: Direct firmware load for iwlwifi-ty-a0-gf-a0-59.ucode failed with error -2
[    4.586562] iwlwifi 0000:01:00.0: Direct firmware load for iwlwifi-ty-a0-gf-a0-59.ucode failed with error -2
.....................

Among them, iwlwifi-ty-a0-gf-a0-59.ucode represents the missing driver file, you can download the firmware: click here.
For more firmware downloads: click here.

Bluetooth

Check log:

dmesg | grep hci
.....................
[    6.301299] bluetooth hci0: loading /lib/firmware/intel/ibt-12-16.sfi failed with error -20
[    6.301321] bluetooth hci0: Direct firmware load for intel/ibt-12-16.sfi failed with error -20
.....................

If the above content appears, it means that the corresponding file is missing (for example, the above log indicates that the "/lib/firmware/intel/ibt-12-16.sfi" driver file is missing), you can download the latest driver on the Internet by yourself, or you can use our provided Driver file, in the firmware/intel folder, just copy /lib/firmware/intel
Execute hciconfig

pi@raspberrypi:~ $ hciconfig 
hci0:	Type: Primary  Bus: USB
	BD Address: D8:3B:BF:46:2B:1A  ACL MTU: 1021:4  SCO MTU: 96:6
	UP RUNNING 
	RX bytes:813 acl:0 sco:0 events:62 errors:0
	TX bytes:3683 acl:0 sco:0 commands:62 errors:0

Among them, the UP RUNNING state means normal operation, and the DOWN state does not work normally, which may be closed or lack of driver files If it is DOWN, you can try to execute it. If there is insufficient permission, please add sudo: 

hciconfig hci0 up
more commands
turn off bluetooth hciconfig hci0 down
reset bluetooth hciconfig hci0 reset
Scan for bluetooth devices hcitool scan

Among them, hci0 is the number of Bluetooth devices. If your cm4 comes with a WIFI Bluetooth module, then pay attention to observe the Bus: the back is USB or UART, and the Bluetooth device of AX200 is USB Bluetooth.


Jetson Xavier NX

The latest system only supports WIFI, not Bluetooth because the kernel is only 5.10 kernel.

Debug Notes

  1. Check the hardware connection first in the linux environment, "lspci" can see that the device is marked and connected correctly.
  2. In the Linux environment, check the log "dmesg | grep iwlwifi" to confirm what driver files are missing.
  3. Linux environment If there is no output from "dmesg | grep iwlwifi", you can try to restart or check the Linux kernel version to ensure that the Linux kernel version is greater than or equal to 5.11.
  4. In the Linux environment, check the Bluetooth startup status through "dmesg | grep bluetooth" and check whether the driver file is missing.
  5. The Linux environment uses "hciconfig" to ensure that the Bluetooth device works normally.
