I was in the original system Windows7 desktop installed ubuntu 16.04 a computer, so now this computer is a dual system. Normal wired network links when you open a Windows system. But after entering the network can not be linked ubuntu 16.04, the upper right corner there is a network link logo ( this is very important, explained ubuntu 16.04 NIC driver is a good system, you can also enter the command ping 127.0.0.1 to see enter the network card driver is in good condition). But you will be prompted connection has been lost, you are now in a disconnected state
Solution:
Into the Windows system, enter cmd command line window, type ipconfig / all
A note as the IPv4, subnet mask, default gateway, DNS server four values, DNS server, the server may have multiple values, such as on a trip to remember 8.8.8.8 or 114.114.114.114
Ubuntu into the system again
