the difference between a in order to distinguish the interfaces between different systems, but also give you the most generic tutorial, so we this tutorial is given priority to with the command line.[dear reader, please don't panic, is all some very good fit command ^_^]

first of all, we need to press Microsoft icon + R keys out "Run "Window.Then enter "Cmd"And click "Identify "The key.In

out of the window, black input "Ipconfig"And press enter button.To view "Ethernet adapter "Or "Wireless LAN adapter "The inside of the parameters.Graphic IPv4 address, subnet mask, default gateway is that we are looking for information.More than

here, we input command "Ping 192.168.199.109 "And click the enter key.This address is the IPv4 address above.If appear below reply, said local connection is normal.But if a "The request timeout "This kind of information, has said his card above the cable may be poor contact, should be to tight line, if still won't do, then you should change another Internet line.

if you have questions, please refer to the following four:
