See if you can get a command prompt by going to the the Window logo, usually on the bottom left of the screen. From there, click on RUN. Type in cmd and hit the Enter key.
You should see a black window with white text. At the > prompt, type in ipconfig /all.
That will tell you what your IP address is. If you have a router, it'll be something like 192.168.x.y with x being usually 0, 1, or 2. The y value is usually between 1 and 255.
Once you have that try to PING comand. At the > prompt, type in
ping followed by a space and the IP address of your Default Gateway. You should get a response.
If that works, try PING www.google.com.
Also try PING 220.127.116.11
See if these work or if you get a time out error.
