Debian 笔记本电脑上没有 wifi 和蓝牙

所以我最近在笔记本电脑上安装了 Debian，从那时起我就无法连接到任何 wifi 网络或蓝牙设备。“网络”设置中根本没有无线选项。

通过一些快速的谷歌搜索，我安装了缺失的“固件”，但仍然没有任何变化。

我到底该做什么？

编辑：我使用 lspci 检查了我的 wifi 驱动程序，结果如下：

lspci -vv -s 03:00.0

03:00.0 Network controller: Broadcom Limited BCM43142 802.11b/g/n (rev 01)

我正在使用 Gnome 桌面环境。

来自Debian 维基：

  1. 添加non-free到您现有的包源中/etc/apt/sources.list。

    例子：

    deb http://httpredir.debian.org/debian/ stretch main contrib non-free

  2. 安装最新的内核、内核头文件和broadcom-sta-dkms包：

    apt-get update
apt-get install linux-image-$(uname -r|sed 's,[^-]*-[^-]*-,,') linux-headers-$(uname -r|sed 's,[^-]*-[^-]*-,,') broadcom-sta-dkms

  3. 卸载冲突的模块：

    modprobe -r b44 b43 b43legacy ssb brcmsmac bcma

  4. 加载wl模块：

    modprobe wl


如果缺失，安装 gnome 网络管理器

apt-get install network-manager-gnome

然后注销并重新登录。通知区域/系统托盘中将出现一个新的小程序（计算机图标）。

我可以遗憾地确认broadcom-sta-dkms在内核 4.19.0-0.bpo.4-amd64 上编译失败：

但是它确实在内核 4.4.0 上编译。

如何broadcom-sta-dkms从 Debian backports 存储库安装最新版本的说明：

  1. 删除无效的broadcom-sta-dkms

    apt-get remove broadcom-sta-dkms

  2. 在以下位置添加 stretch-backports 的存储库条目/etc/apt/sources.list

    echo "deb http://ftp.debian.org/debian stretch-backports main contrib non-free" >> /etc/apt/sources.list

  3. 更新软件包索引并broadcom-sta-dkms从 backports 存储库安装

    apt-get update
apt-get -t stretch-backports install broadcom-sta-dkms
