Why can't I run my computer through my router

My computer works fine using my cable modem with no issues. Once a hookup my router ( I have tried 3 different routers) I lose connectivity. The message I get is:

Local Area Connection 2

This connection has limited or no connectivity. You might not be able to access the Internet or some network resources. For more info. click this message. When I do that I get the following:

The problem occurred because the network did not assign a network address to the computer.

Please help.

  1. Check TCP/IP Properties.

    Start, Connect To, Connection, Properties, Scroll Down TCP/IP and highlight, click Properties and check that Obtain DNS and IP address automatically are enabled.
  2. Also make sure you are plugging into the switch ports, labeled 1 through 4. The WAN port should have the modem plugged into it.
    Confirm you have a green link light on the router as well.
  3. What type of router do you have? Who makes it? We can get you a diagram on what to plug in where.

    Thanks for getting back to me, but I have windows xp and don't know how to select TCP/IP properties
  5. Well, the steps described work with XP:

    Start, Connect To, Connection, Properties, Scroll Down TCP/IP and highlight, click Properties and check that Obtain DNS and IP address automatically are enabled.
  6. alternately, control panel - network connections - local area connection - right click on that, then properties. scroll down to tcp/ip and click on properties.

    also try running a command prompt, then type "ipconfig /all" and let us know what that says.
