No Internet connection through a Router ...Please help

[abou202]

I am trying to setup a wireless internet connection using Linksys (WRT54G2) wireless router. I currently have internet service by using an ethernet cable directly from my laptop to to the cable modem (My ISP is Time Warner) When I go through the steps of configuring the wireless router and get to the point where I have to connect the an Ethernet cable from the cable modem to the router and an ethernet cable(Blue) from the router to my PC, I loss internet connection...Please

Thanks

Did you turn off the modem when you changed from the connection to the computer to the connection to the router? That's a REQUIRED step for standard DOCSIS compliant modems.

The modem was turn off when I change connection from from Modem directly to the Computer to modem through the router and computer.

Thanks

What is the exact make/model of the modem?

When connected directly to the modem and on-line, let's see this.

Hold the Windows key and press R, then type CMD to open a command prompt:

In the command prompt window that opens, type type the following command:

IPCONFIG /ALL

Right click in the command window and choose Select All, then hit Enter.

If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here.
