前言: 工業電腦客群於工業製造、數位看板、醫療、POS、AMR等領域應用上,越來越多終端客戶的產品規格開始支援WiFi 6/6E (802.11ax)

 

無線連網技術, 搭載選用Intel NEX WiFi 6E AX210模塊。鑒於Linux OS(Ubuntu)環境的客戶於Kernel Version進版整合上有相關問題產生,希望藉由此文能夠幫助到客戶端快速解決Linux WiFi Driver安裝問題與完成系統驗證。

 

Intel NEX WiFi 模塊 – Software Components 安裝元件說明 :

	(1)WiFi Driver	(2)WiFi Firmware	WiFi PNVM
軟體項目	iwlwifi backport driver	*.ucode file	pnvm file (Platform NVM)
功能說明	Driving WiFi module to work on the platforms. (Communicate with daemon/app and platform ( e.q. ACPI…) to allowing upper layer to interact with low level MAC/PHY.) New features update for the specific country WiFi 6E features support update and certification test.	The WiFi module requires firmware to operate. ( Mainly it controls with 802.11 MAC and PHY. ) Each module firmware binary was released along with driver package together.	The WiFi module requires pnvm file to operate together. ( It include the information regarding regulatory and SKU ID. ) Following *.ucode version released to update it as must.

Linux* Supporting for Intel® Wireless Adapters – WiFi Driver連結安裝說明 :

• 執行iwlwifi backport driver Git URL更新 ( Core 81 version–Example ) & 安裝 :
https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/backport-iwlwifi.git
git://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/backport-iwlwifi.git

Intel WiFi 6E AX210 :
git clone https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/backport-iwlwifi.git-brelease/core81

• Check out the git branch origin/release/core81, Build / install the driver as below.
Intel WiFi 5 AC9260 :
git clone https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/backport-iwlwifi.git-brelease/core43

• Check out the git branch origin/release/core43, Build / install the driver as below.

1. Build Intel iwiwifi backport driver:
$ cd ~/workspace/backport-iw/wifi
$ make defconfig-iw/wifi-public
$ sed -i's/CPTCFG_IWLMVM_VENDOR_CMDS=y/# CPTCFG_IWLMVM_VENDOR_CMDS is not set/'

$ make -j4

Install Intel iwiwifi backport driver:
$ sudo make install
$ ismod | grep iwl

Linux* Support for Intel® Wireless Adapters – Firmware 連結安裝說明 :

(1) Default 1st *.ucode firmware version as below table and contents for reference.
https://www.intel.com/content/www/us/en/support/articles/000005511/network-and-i-o/wireless-networking.html

(2) To get the latest Intel wireless firmware version for newer kernels :

Please use the firmware git tree instead.

• 執行Intel WiFi AX210 firmware Git Clone更新 ( Core 81 version–Example ) & 安裝: https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git

 

• iwlwifi-ty-a0-gf-a0-81.ucode is the firmware file ;

• iwlwifi-ty-a0-gf-a0.pnvm is PNVM file.

• Make sure the *.ucode and *.pnvm are both copied to /lib/firmware/ together.

• If you configure the kernel yourself, make sure firmware loading is enabled.

• https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/

 

$ cd ~/workspace
$ git clone http://git.kemel.org/pub/scm/linux/git/firmware/linux-firmware.git
$ cd ~/workspace/linux-firmware
$ sudo cp iwlwifi-*.ucode /lib/firmware

Reboot Linux system and check the Target Device :
• dmesg | grep iwl to see if at least one version of firmware is loaded.
• Wireless firmware version : ty-a0-gf-a0-81.ucode ( Intel x86 Platform)
• iwlwifi WiFi Driver Version : iwlwifi-stack-public:release/core81:11349:21b66ac8
