linux - Debian 8. 加载 iwlwifi 失败

Question

我使用网盘 iso 安装 debian，显然缺少固件文件:rtl_nic_rtl8411-2.fw 和 iwlwifi，所以我无法使用 wifi。我的笔记本电脑使用的是 intel wireless-AC 8260，我已经将内核更新到 4.8

Dmesg 输出:

    iwlwifi 0000:02:00.0: firmware: failed to load iwlwifi-8000C-24.ucode (-2)

uname -a 输出:

 Linux debian 4.8.0-0.bpo.2-rt-amd64 #1 SMP PREEMPT RT Debian 4.8.11-1~bpo8+1 (2016-12-14) x86_64 GNU/Linux

我不确定我是否正确安装了 iwlwifi 8000。这是我的/lib/firmware 输出。

我已将非自由资源复制到我的/etc/apt/sources.list 中

deb http://ftp.us.debian.org/debian/ jessie main contrib non-free#
deb http://mirror.one.com/debian/ jessie-backports main contrib non-free 

当我执行 apt-get iwlwifi 时:

firmware-iwlwifi is already the newest version.

我已经尝试让这个工作 2 天了，但没有成功，我错过了什么？我是 Linux 的新手，所以我非常感谢初学者可以理解的答案。

Answer 1

您缺少的包是 firmware-iwlwifi这是一个非免费包。官方 Debian 镜像构建仅包含自由软件。

方法#1 - 使用以太网连接

因此，要安装它，您需要将 non-free 和 contrib 组件添加到 /etc/apt/sources.list

参见:https://wiki.debian.org/SourcesList#Example_sources.list

然后，

sudo apt-get update
sudo apt-get install firmware-iwlwifi

方法 #2 - 没有互联网连接

从here手动下载(从其他有互联网连接的机器)你的版本的deb包。 .

如果您使用的是 Debian 稳定版，请检查: https://packages.debian.org/stable/firmware-iwlwifi

然后，

dpkg -i firmware-iwlwifi*.deb

重新启动。

同样的过程应该适用于 Realtek 驱动程序。
