我最近安装了 ubuntu 12.04 LTS，并尝试了所有方法来使我的以太网电缆工作...不幸的是，没有一种方法对我有用。以下是我运行的一些测试：
lspci -nnk | grep -i ethernet给出05:00.0 Ethernet controller [0200]: Atheros Communications Inc. AR8161 Gigabit Ethernet [1969:1091] (rev 10)。
ifconfig给出：

我能做些什么？
答案1
8161 卡是许多问题的根源，就像您的问题一样。您可以找到与 8161 卡相关的帖子列表这里。该问题似乎与当前内核版本提供的驱动程序有关；回滚驱动程序似乎在大多数情况下都有效。一个建议的修复方法是发出以下终端命令，这显然是有效的：
apt-cache search linux-backports-modules
sudo apt-get install linux-backports-modules-cw-3.6-quantal-generic
sudo modprobe alx
