Intel AX201 Wi-Fi 6 和以太网无法在 Ubuntu 20.04 和 21.10 上运行

Question

我发布了一个类似的问题，但我正在尝试扩展它，因为我现在已经尝试了两个版本，但似乎仍然无法正常工作。我浏览了大约 20 个不同的页面，并尝试了许多不同的建议，但似乎仍然无法使其发挥作用。我对 Linux 很陌生，不像社区中的很多人那样对技术感兴趣。任何帮助，将不胜感激。

我禁用了 Fastboot，也禁用了 safeboot。到目前为止，Windows 10 运行没有出现任何问题。我尝试更新固件，但这似乎也没有解决问题。我将尝试再次调查 netplan .yaml 文件。

我的朋友认为这可能与内核模块有关，但这深入到了我们都没有经验的领域。

请告诉我您希望我发布什么内容，我将从头开始。

我有同样的错误：

[   12.810257] iwlwifi 0000:00:14.3: no suitable firmware found!
[   12.810259] iwlwifi 0000:00:14.3: minimum version required: iwlwifi-so-a0-hr-b0-39
[   12.810260] iwlwifi 0000:00:14.3: maximum version supported: iwlwifi-so-a0-hr-b0-63

从linux-firmware下载固件后：iwlwifi-so-a0-hr-b0-64.ucode WiFi 工作没有问题。

如果有人拥有 AX201 但在日志中没有看到提到的错误，请使用您可以找到的最新内核。对我来说，只有5.16版本有效（5.15 无效）。您可以在这里找到一个：https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.16-rc7/amd64/：

wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.16-rc7/amd64/linux-headers-5.16.0-051600rc7-generic_5.16.0-051600rc7.202112262230_amd64.deb
wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.16-rc7/amd64/linux-headers-5.16.0-051600rc7_5.16.0-051600rc7.202112262230_all.deb
wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.16-rc7/amd64/linux-image-unsigned-5.16.0-051600rc7-generic_5.16.0-051600rc7.202112262230_amd64.deb
wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.16-rc7/amd64/linux-modules-5.16.0-051600rc7-generic_5.16.0-051600rc7.202112262230_amd64.deb
sudo dpkg -i *.deb

linux-headers 安装可能会因依赖关系而失败，但内核本身会安装。

Answer 2

我已经搜索了很多地方和很多资源来寻找所需但没有找到的固件文件 iwlwifi-so-a0-hr-b0-XX.ucode，其中 XX 是 39 到 63 之间的任意数字。从你的 dmesg 中：

[   12.810257] iwlwifi 0000:00:14.3: no suitable firmware found!
[   12.810259] iwlwifi 0000:00:14.3: minimum version required: iwlwifi-so-a0-hr-b0-39
[   12.810260] iwlwifi 0000:00:14.3: maximum version supported: iwlwifi-so-a0-hr-b0-63
[   12.810261] iwlwifi 0000:00:14.3: check git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git

我一直找不到。因此我只有两个建议。首先，尝试通过重命名您拥有的 -64 版本来欺骗驱动程序：

cd /usr/lib/firmware
sudo cp iwlwifi-so-a0-hr-b0-64.ucode  iwlwifi-so-a0-hr-b0-63.ucode

重启。查看：

sudo dmesg | grep iwl

固件错误是否已解决？无线网络是否按预期工作？

我的最后一个建议是在此处提交错误报告： https: //bugs.launchpad.net/ubuntu包含上面的 dmesg 日志。
