如何加载 iwlwifi 驱动程序？

我正在尝试使用板载 wifi，但似乎无法加载。使用5.2.13Ukku 中最新的内核。（技嘉 X570 Aorus Master）

我发现一些文章表明该设备应该从 5.1 内核开始支持，但它没有加载。

答案1

显然，我还需要下载并提取英特尔的 AX200 wifi 驱动程序并将它们移入/lib/firmware

答案2

英特尔已经发布了一系列 AX200 固件，这些固件已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/firmware 中的最新固件。但是，由于编译的内核与特定固件文件有绑定。如果您升级内核，效果会更好。我在安装 ubuntu 20.10 发行版并执行 apt-get update 和 apt-get upgrade 后成功完成了此操作，完成后，如果您阅读第一个链接中的错误报告，就会发现最新的 AX200 固件已分发，早期的固件有各种问题，因此请尽可能使用最新的固件
