英特尔无线适配器突然不工作 - Ubuntu 20.04.3

我有一个英特尔公司的 Wi-Fi 6 AX201 wifi 适配器，重启后突然无法工作。现有的 askubuntu 解决方案都无法帮助我解决我的问题。

我在日志中发现了一个错误代码，我想诊断一下：

有人知道如何解决这个问题吗？

Ubuntu 官方软件包 linux-firmware 适用于 22.04，这是一个测试版本，还包含固件版本 -66、-67 和 -68。让我们安装它们，看看无线现在是否可以正常工作。

请打开终端并执行：

cd /usr/lib/firmware
sudo wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/iwlwifi-QuZ-a0-hr-b0-66.ucode
sudo wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/iwlwifi-QuZ-a0-hr-b0-67.ucode
sudo wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/iwlwifi-QuZ-a0-hr-b0-68.ucode

此外，如果当前固件版本 -63 因某种原因损坏，让我们安装一个新副本：

sudo wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/iwlwifi-QuZ-a0-hr-b0-63.ucode

重新启动并告诉我们是否有任何改进。

答案2

我为此苦苦挣扎并尝试了所有的建议...然后，当我这样做并重新启动后，它就起作用了！

编辑：/etc/default/grub

来自：GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

至：GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pcie_aspm=force"

运行：sudo update-grub

重新启动 =)
