答案1
看来你没有IPv4地址，设置此值：
首先，打开终端，然后键入以下内容：
sudo nano /etc/network/interfaces
这将打开一个文件，在文件中键入以下内容：
auto eth0
iface eth0 inet static
address 192.168.1.100
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
gateway 192.168.1.1
(输入你自己的IP地址，而不是上面的，或者，如果不需要静态IP，只需在文件中键入以下行：
auto eth0
iface eth0 inet dhcp
保存文件(CTL+X，Y，enter )，并重新启动网络服务：
sudo service network-manager restart
希望这有帮助。
