Lenovo ThinkPad Ubuntu16.04 support WIFI6-AX200

reference:

First, disassemble change WIFI card

The intermediate cover plate, three screws up, there can be seen near the fuselage keyboard WIFI card

And AX200 are narrow card, the interface is not the same under an electric shock, but still fit (AX200 specification describes support Thinkpad)

Antenna Note: black antenna connected to a button, buttons gray antenna ground 2

Second, the application update

sudo apt-get update -y
sudo apt-get upgrade -y

Third, to update the kernel 5.1

Need to upgrade to the latest Linux kernel> 5.1, and uses the latest wireless adapter firmware. I have to upgrade to the 5.1 version of the Linux kernel

Download and install the kernel's official website (Ubuntu 16.04 64-bit systems):

cd /tmp/
wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.1/linux-headers-5.1.0-050100_5.1.0-050100.201905052130_all.deb
wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.1/linux-headers-5.1.0-050100-generic_5.1.0-050100.201905052130_amd64.deb
wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.1/linux-image-unsigned-5.1.0-050100-generic_5.1.0-050100.201905052130_amd64.deb
wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.1/linux-modules-5.1.0-050100-generic_5.1.0-050100.201905052130_amd64.deb
sudo dpkg -i *.deb

最好使用sudo dpkg -i xxx.deb一个个安装，看每一个deb包是否需要依赖。

安装linux-headers-5.1.0-050100-generic_5.1.0-050100.201905052130_amd64.deb时出现依赖libssl1.1 is not installed问题，解决方案参考如下：

https://www.cnblogs.com/gambler/p/9574596.html

下载libssl1.1_1.1.0g-2ubuntu4.1_amd64.deb进行dpkg安装

其他32位系统可参考：

cd /tmp/
wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.1/linux-headers-5.1.0-050100_5.1.0-050100.201905052130_all.deb
wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.1/linux-headers-5.1.0-050100-generic_5.1.0-050100.201905052130_i386.deb
wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.1/linux-image-5.1.0-050100-generic_5.1.0-050100.201905052130_i386.deb
wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.1/linux-modules-5.1.0-050100-generic_5.1.0-050100.201905052130_i386.deb
sudo dpkg -i *.deb

安装完成，重启设备生效

sudo reboot

启动完成
uname -a

四、升级WI-FI驱动

升级iwlwifi驱动程序，如下命令：（注意打开CPTCFG_CFG80211_WEXT支持iwconfig）

git clone --single-branch --branch release/core45 https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/backport-iwlwifi.git
cd backport-iwlwifi/
make defconfig-iwlwifi-public
sed -i 's/CPTCFG_IWLMVM_VENDOR_CMDS=y/# CPTCFG_IWLMVM_VENDOR_CMDS is not set/' .config
sed -i 's/# CPTCFG_CFG80211_WEXT is not set/CPTCFG_CFG80211_WEXT=y/' .config
make -j4
sudo make install

中间有ssl报错可以不用理会

五、安装AX200 官方固件

从下面的链接下载最新的固件。

https://www.intel.com/content/www/us/en/support/articles/000005511/network-and-i-o/wireless-networking.html

tar xzvf iwlwifi-cc-46.3cfab8da.0.tgz
cd iwlwifi-cc-46.3cfab8da.0/
cp iwlwifi-cc-a0-46.ucode /lib/firmware/

七、WIFI6抓包

iwconfig配置：

sudo killall -9 wpa_supplicant
sudo ifconfig wlp4s0 down
sudo iwconfig wlp4s0 mode monitor
sudo ifconfig wlp4s0 up

aircrack-ng configuration:

sudo airmon-start wlp4s0 
sudo airodump-of mon0 
sudo airmon-stop wlp4s0
