直到上个月（2015 年 11 月 17 日），以太网连接仍在运行，后来进行了软件更新，我的有线连接就停止工作了。
但我仍然可以连接 wifi。

我尝试了以下
sudo dhcpclient eth0：终端挂了，我没有收到任何回应gksu gedit /etc/network/interfaces我也尝试通过添加行来编辑eth0。但之后我的有线网络根本无法被识别，在此之前我至少能够在连接信息中看到 IP 地址，因此我删除了这些行。尝试下载
compat-drivers-2013-03-04-u.tar.bz2但make出现以下错误error "ERROR: compat-drivers by default supports kernels >= 2.6.24, try enabling only one driver though"甚至更换了新电缆，但是没有用。

我建议您更新以太网驱动程序alx。将此包下载到您的桌面：https://www.kernel.org/pub/linux/kernel/projects/backports/2015/11/15/backports-20151115.tar.gz右键单击它并选择“在此处提取”。现在返回终端：
sudo apt-get install linux-headers-generic build-essential
cd ~/Desktop/backports-20151115
make defconfig-alx
make
sudo make install
重启并告诉我们是否有任何改进。我们可能还需要再进一步。
