我正在尝试学习 Linux，但在使用 wifi 时遇到了问题。我运行的是 Ubuntu 21.04，内核为 5.11.0-22-generic。在 wifi 设置中的网络选项卡下，我没有选项，好像我的 wifi 卡未被检测到。我搜索并尝试了几乎所有我能在这个论坛上找到的解决方案，但似乎都不起作用。我已经从英特尔网站下载了相应的驱动程序，并将文件移动到 /lib/firmware 目录中，正如 README 文件中所述。当我启动 Windows 时，Wifi 工作正常。Ubuntu 安装在外部 SSD 上。我不太确定解决此问题所需的所有信息，但我提供了目前掌握的信息。谢谢你的帮助。

dkms status
backport-iwlwifi, 8613, 5.11.0-22-generic, x86_64: installed (WARNING! Diff between built and installed module!) (WARNING! Diff between built and installed module!) (WARNING! Diff between built and installed module!) (WARNING! Diff between built and installed module!) (WARNING! Diff between built and installed module!) (WARNING! Diff between built and installed module!)
答案1
问题出在 iwlwifi 内核模块上。它无法识别最新的 Intel AX201 调制解调器卡。为什么？因为 iwlwifi 不是针对 Intel AX201 的设备代码进行编码的！
让我们修补 iwlwifi 内核模块，以便它可以与 Intel AX201 一起工作。
安装 Ubuntu 21.04
从 GRUB“附加选项”菜单启动到 5.11.0-2x 内核
安装
backport-iwlwifi-dkmssudo apt updatesudo apt install backport-iwlwifi-dkms在内核 > 5.4.0 上将无法完全安装。这是预料之中的。
该软件将源代码安装到
/usr/src/backport-iwlwifi-8613
编辑
dkms.conf源代码目录中的文件/usr/src/backport-iwlwifi-8613sudo -H gedit /usr/src/backport-iwlwifi-8613/dkms.conf编辑文件并更改
OBSOLETE_BY="5.4.0"为#OBSOLETE_BY="5.4.0"
编辑
drv.c源代码目录中的文件/usr/src/backport-iwlwifi-8613/drivers/net/wireless/intel/iwlwifi/pciesudo -H gedit /usr/src/backport-iwlwifi-8613/drivers/net/wireless/intel/iwlwifi/pcie/drv.c在 Gedit 偏好设置中启用“显示行号”
在 #447-#448 处的其他 0xA0F0 ID 行下方添加以下行...
IWL_DEV_INFO(0xA0F0, 0x6074, iwl_ax201_cfg_qu_hr, NULL),
重建修补后的 dkms 模块
sudo dkms remove backport-iwlwifi/8613sudo dkms add backport-iwlwifi/8613sudo dkms build backport-iwlwifi/8613sudo dkms install backport-iwlwifi/8613
通过 GRUB 重新启动到 5.11.0-2x 内核，然后重新测试 AX201
清除 5.13.4 内核
dpkg -l *5.13.4*# 列出 4 个要清除的 linux* 软件包名称sudo dpkg -P package_name#{1|2|3|4}# 对四个包名分别执行此操作
sudo update-grub# 更新 GRUB正常重启
提交错误报告至https://bugs.launchpad.net/ubuntu针对
linux-modules-extra-5.11.0-25-generic在Samsung Galaxy Book Flex2 Alpha
笔记：当前安装的 AX201 固件可以在以下位置查看ls -al /lib/firmware/iwlwifi-Qu-*
笔记：如果需要其他更新的固件代码，请参阅https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/iwlwifi-Qu-*
笔记：较新的内核可以在以下位置找到https://kernel.ubuntu.com/~kernel-ppa/mainline/
