我已经成功连接Ubuntu 和 Windows 中的 WIFI。
（I have dual boot:Ubuntu 14.04 installed & upgraded to 14.04.1 and Windows 8.1）
但我有仅在 Ubuntu 中有线连接存在问题（尽管它在 Windows 上运行良好）。
我咨询过这里但没有运气。我想我遇到了一些问题静态设置 IP 地址从 Ubuntu 端。显示了连接，但我无法访问互联网，甚至无法访问网关（我的意思是192.168.1.1）。
我按照描述的方式这里：
所以我的网络管理器配置文件好像：
[main]
plugins=ifupdown,keyfile
#dns=dnsmasq
[ifupdown]
managed=true
但是我删除了其他部分这是默认的。
和我的界面就好像：
auto lo
iface lo inet loopback
iface eth0 inet static
address 192.168.1.102 #I have seen from Windows that it's 1.102
gateway 192.168.1.1 # 1.1 is because I use 192.168.1.1 to access router settings
netmask 255.255.255.0
dns-nameservers 8.8.8.8 8.8.4.4
我使用以下命令重新启动新设置
sudo service network-manager restart
sudo service networking restart
sudo service resolvconf restart
我现在有

点击链接后，我有了新的设置（之前是 AutoEthernet，新设置是 ifeth(up)。我想我应该尝试连接 ifeth0(up)）。
感谢您的时间！！
