我有一台 Toshiba Satellite P870 笔记本电脑，无线连接正常，但 eth0 没有显示在网络上。但它确实显示在 lspci 中：

这是 /etc/network/interfaces 文件

iface lo inet loopback
auto eth0
iface eth0 inet dhcp
这是lshw-C 网络：

答案1
Debian net_device 标头在内核版本 3.8 中已更改，因为某些驱动程序遇到了问题。我在 Ubuntu 14.04 上使用同一系列的以太网卡时遇到了这个问题，以下命令对我有用：
wget https://www.kernel.org/pub/linux/kernel/projects/backports/2013/03/04/compat-drivers-2013-03-04-u.tar.bz2
./scripts/driver-select alx
make
sudo make install
reboot
完整论坛可以在这里找到这里。
另外，此软件包中有许多新的 atheros 驱动程序。返回无线并尝试运行以下命令：
sudo apt-get install bcmwl-kernel-source
