我最近买了一台三星 Galaxy Book Odyssey，希望能双启动 Kubuntu 和 Windows。它有一个 Intel WiFi 6 AX201 无线网卡。
我无论如何都无法让 Kubuntu 使用无线网卡。在 Windows 上它运行良好。
Windows 中已禁用快速启动，因此不会影响卡。
我已经尝试了Wifi 无法使用 Ubuntu impish 21.10 内核 5.13.0 Samsung Galaxy Book Flex2两次，但至今无果。
我也尝试安装较新的内核版本，看看该卡是否与它们兼容，并尝试安装英特尔提供的驱动程序https://www.intel.com/content/www/us/en/support/articles/000005511/wireless.html
的输出sudo dmesg | grep iwlw为：

答案1
终于能让这张卡上的 wifi 工作了。它位于当前的 iwlwifi 反向移植中：
Sudo apt-get install git build-essential
git clone https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/backport-iwlwifi.git
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
然后重新启动，wifi 就可以正常工作了。
（说明修改自这里因为它已被直接添加到反向移植中，所以不再需要进行任何文件更改。

使用此答案来修补你的内核模块 Intel AX201 Wi-Fi 6 无法在 Ubuntu 21.04 上运行
就我在 Kubuntu 上的情况来说，22.10我采取了以下步骤：
安装 backport-iwlwifi-dkms
sudo apt install backport-iwlwifi-dkms编辑
/usr/src/backport-iwlwifi-9904/dkms.conf
#OBSOLETE_BY="6.1.0"
- 添加
43f0/6074到/usr/src/backport-iwlwifi-9904/drivers/net/wireless/intel/iwlwifi/pcie/drv.c
IWL_DEV_INFO（0x43f0，0x6074，iwl_ax201_cfg_qu_hr，NULL），
- 重建 iwlwifi
sudo dkms remove backport-iwlwifi/9904sudo dkms add backport-iwlwifi/9904sudo dkms build backport-iwlwifi/9904sudo dkms install backport-iwlwifi/9904
- 重启并查看 dmesg
$ sudo dmesg | grep iw
