无法连接有线网络

无法连接有线网络

我正在使用 Ubuntu 12.10。我的互联网连接工作正常。我尝试在更改 IP 后连接大学 LAN,但没有成功。然后我更改为以前的 IP 并尝试连接,但现在显示Connection established没有互联网访问。输出ifconfig没有wlaneth1显示interrupt17

$ ifconfig
eth1      Link encap:Ethernet  HWaddr 00:26:22:c8:2d:2a  
          inet addr:192.168.61.57  Bcast:192.168.61.255  Mask:255.255.255.0

          RX bytes:64128 (64.1 KB)  TX bytes:64128 (64.1 KB)

我该怎么做才能让它正常工作?

答案1

按下Ctrl+Alt+T,然后在命令提示符中输入:

echo on | sudo tee /sys/class/net/eth0/device/power/control

之后,拔下以太网电缆,然后重新插入。它应该可以连接... :)
