那些遇到过的问题

Intel AX201 Wi-Fi 6 无法在 Ubuntu 21.04 上运行

New*_*ntu 3 wireless networking iwlwifi

我正在尝试学习 Linux，但在使用 wifi 时遇到了问题。我正在运行带有 5.11.0-22-generic 内核的 Ubuntu 21.04。我的 wifi 设置中的网络选项卡下没有任何选项，就好像未检测到我的 wifi 卡一样。我已经搜索并尝试了在这个论坛上可以找到的几乎所有解决方案，但似乎没有任何效果。我已从英特尔网站下载了适当的驱动程序，并将文件移至 /lib/firmware 目录，正如自述文件中所述。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，但我已经提供了迄今为止所掌握的信息。谢谢您的帮助。

The problem is with the iwlwifi kernel module. It doesn't recognize the latest Intel AX201 modem card. Why? Because iwlwifi isn't coded for the device codes of the Intel AX201!

Let's patch the iwlwifi kernel module so that it works with the Intel AX201.

  • Install Ubuntu 21.04

  • Boot to the 5.11.0-2x kernel from the GRUB "Additional Options" menu

  • Install backport-iwlwifi-dkms

    • sudo apt update

    • sudo apt install backport-iwlwifi-dkms

    • This will fail to fully install on kernels > 5.4.0. This is expected.

    • This software installs source code into /usr/src/backport-iwlwifi-8613

  • Edit the dkms.conf file in the source code directory /usr/src/backport-iwlwifi-8613

    • sudo -H gedit /usr/src/backport-iwlwifi-8613/dkms.conf

    • Edit the file and change OBSOLETE_BY="5.4.0" to #OBSOLETE_BY="5.4.0"

  • Edit the drv.c file in the source code directory /usr/src/backport-iwlwifi-8613/drivers/net/wireless/intel/iwlwifi/pcie

    • sudo -H gedit /usr/src/backport-iwlwifi-8613/drivers/net/wireless/intel/iwlwifi/pcie/drv.c

    • Enable "Display line numbers" in Gedit preferences

    • Add the following line below the other 0xA0F0 ID lines at #447-#448...

      IWL_DEV_INFO(0xA0F0, 0x6074, iwl_ax201_cfg_qu_hr, NULL),

  • rebuild the patched dkms module

    • sudo dkms remove backport-iwlwifi/8613

    • sudo dkms add backport-iwlwifi/8613

    • sudo dkms build backport-iwlwifi/8613

    • sudo dkms install backport-iwlwifi/8613

  • reboot to the 5.11.0-2x kernel via GRUB, and retest the AX201

  • purge the 5.13.4 kernel

    • dpkg -l *5.13.4* # list 4 linux* package names to purge

    • sudo dpkg -P package_name#{1|2|3|4} # do this for each of the four package names

  • sudo update-grub # update GRUB

  • reboot normally

  • file a bug report at https://bugs.launchpad.net/ubuntu against package linux-modules-extra-5.11.0-25-generic running on a Samsung Galaxy Book Flex2 Alpha

注意：当前安装的 AX201 固件可以在以下位置查看ls -al /lib/firmware/iwlwifi-Qu-*

注意：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-*

注意：可以在https://kernel.ubuntu.com/~kernel-ppa/mainline/找到较新的内核

  • 我可以得到 7 1/2 分吗？;-)) (2认同)
  • 谢谢 ！！！@heynnema 我也是三星 Galaxy Flex2（使用 wifi 适配器 AX-201）用户，我遇到了同样的问题...你的答案救了我当我看到 wifi-list 时，我真的很兴奋并尖叫 TT 我爱你！我想为下一个用户发表评论。我在080821上安装了ubuntu 21.04，但内置了内核5.11.0-16。我在任何地方都找不到 5.11.0-2x，所以我使用了 5.11.1 并且它有效。（5.11.16 或 5.13.8 不起作用！） (2认同)
