Linux 在 Intel 芯片组上看不到 Wi-Fi。 “固件：加载 iwlwifi 失败”错误（已解决）

系统未检测到英特尔制造的内置 Wi-Fi 适配器。 Linux 看不到 Wi-Fi 设备，就好像它没有连接一样。

要查看自上次启动以来的系统事件，请运行以下命令。


journalctl -b

您可以滚动浏览输出或搜索“iwlwifi”。

要搜索系统日志，可以使用以下命令：


journalctl -b | grep iwlwifi

在输出中，关键行是“firmware: failed to load iwlwifi-9000-*.ucode (-2)”，即无法加载iwlwifi固件。

搜索包存储库


apt search iwlwifi

显示在Kali Linux中，iwlwifi固件放在firmware-iwlwifi包中，安装：


sudo apt install firmware-iwlwifi

在 Ubuntu、Linux Mint 和 Debian 上，运行以下命令安装固件：


sudo apt install firmware-iwlwifi

在 Arch Linux、Manjaro、BlackArch 及其衍生产品上，运行命令：


sudo pacman -S linux-firmware

安装固件并重新启动计算机后，问题将消失，Wi-Fi 适配器将工作。
