无法连接到以太网 Ubuntu 16.04

我能够通过无线驱动器连接到我的网络，但无法通过以太网连接。

我已尝试了其中几项建议。

当我运行 ifconfig 时，我得到：

在 WiFi 上：

有什么建议吗？

dhclient -v eth0返回：

No DHCPOFFERS received. No working leases in persistent database - sleeping.

‘ifconig’ 返回了新的：

eth0:avahi Link encap:Ethernet HWaddr 44:8a:5b:9d:ec:eb inet addr:169.254.12.95 Bcast:169.254.255.255 Mask:255.255.0.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:20 Memory:f7e00000-f7e20000
