Intel WiFi 6 AX200 无法在 Ubuntu 16.04 上运行

根据英特尔，英特尔® Wi-Fi 6 AX200 160MHz 设备仅保证与内核版本兼容5.1+.（供您参考，它适用于内核版本为 的 Ubuntu 18.04.4 LTS 5.3.0-28。）

我想要实现的目标

但是，我需要让英特尔 Wi-Fi 6 AX200 在内核版本为 Ubuntu 16.04.6 LTS 上运行4.15.0-88（原因是我需要 CUDA 10 Toolkit，而截至本文发稿时，CUDA 10 支持的最高内核版本4.15是英伟达。

有什么方法可以让这个内核在 Ubuntu 16.04.6 中工作吗4.15？

我尝试过

  • 我尝试复制固件，方法如下这，但没有区别：

    git clone https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
cd linux-firmware
cp iwlwifi-*.ucode /lib/firmware

  • 我尝试按照以下步骤安装反向移植驱动程序指导但出现以下错误：

    git clone 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
make -j4
sudo make install
...
...

    重启后 Wifi 确实被检测到了。但是，Ubuntu 在尝试连接后立即冻结。

    以下是一些信息。

笔记

  • 在类似邮政，提供的答案是将内核升级到5.1+，但这不符合我的情况的要求。

答案1

我完全不知道该怎么做这个存储库不同于官方移植英特尔的驱动程序。但它确实可以在我的笔记本电脑上运行。

sudo add-apt-repository ppa:canonical-hwe-team/backport-iwlwifi
sudo apt-get update
sudo apt-get install backport-iwlwifi-dkms

答案2

仅针对 ubuntu 16.04 lts 进行了检查

  1. 检查内核版本uname -a，若版本不是4.15则更新至4.15sudo apt-get install --install-recommends linux-generic-hwe-16.04 xserver-xorg-hwe-16.04 若更新内核需要重启

  2. 只需复制并粘贴

git clone https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/backport-iwlwifi.git
cd backport-iwlwifi
sudo make defconfig-iwlwifi-public;sudo make; sudo make install
git clone git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
cd linux-firmware/
sudo cp iwlwifi-* /lib/firmware/
reboot
