以太网在 ubuntu 14.04 LTS 上不起作用

nic*_*uca 2 connection ethernet 14.04

我一直在努力尝试激活我的以太网连接但没有成功。我在戴尔 xps8900 上使用 ubuntu 14.04 LTS。我有一个带有 Windows 7 的双启动,以太网在这个上运行良好。这是我尝试过的:

1) 验证网卡:

2)然后我用ifconfig激活eth0:

sudo ifconfig wlan0 down
sudo ifconfig eth0 up
eth0: ERROR while getting interface flags: No such device
sudo ifconfig wlan0 up

3)查看上面的错误信息,我修改了 70-persistent-net.rules 并重启:

mv /etc/udev/rules.d/70-persistent-net.rules /etc/udev/rules.d/70-persistent-net.rules.old

-> 重启

4)我也看过不同的“eth”:

ifconfig eth0
eth0: error fetching interface information: Device not found
ifconfig eth1
eth1: error fetching interface information: Device not found
ifconfig eth2
eth2: error fetching interface information: Device not found

6)然后:

sudo lshw -C network

笔记

某些系统无法支持 MSI 和/或 MSI-X 中断。如果您认为您的系统需要禁用这种类型的中断,可以使用以下命令构建和安装驱动程序:

# make CFLAGS_EXTRA=-DDISABLE_PCI_MSI install
