如何加载iwlwifi驱动程序？

Question

我试着使用我的车载无线网络，但它似乎没有加载。使用内核5.2.13，这是Ukku的最新版本。(千兆字节X570 Aorus )

我发现一些文章指出，从5.1内核开始，应该支持这个设备，但是它没有加载。

Answer 1

显然，我还需要下载并解压缩英特尔的序200无线网络驱动程序并将它们移动到/lib/firmware中。

Answer 2

英特尔已经分发了一批AX200固件，它们已经进入内核固件存储库https://bugzilla.kernel.org/show_bug.cgi?id=204731#c35 https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/，您可以尝试那些需要安装在/lib/固件中的最新固件。但是，由于编译的内核有绑定到特定的固件文件。如果升级内核，您会做得更好。在安装ubuntu20.10发行版和进行apt-get更新和apt-get升级之后，我成功地做到了这一点，当它完成所有操作时，如果您在第一个链接中阅读了错误报告，那么最新的AX200固件就会被分发，早期的固件已经有了各种各样的错误，所以请尽可能使用最近的固件。
