|At some point when installing the software the prompts should instruct you to connect the router. The router go between the modem and your computer. |
I will state again because you obviously didn't understand. The router can't find an internet connection until you connect the patch cables so the router is in the stream between the modem and your computer.
Are you thinking because that is a wireless router that you don't need to connect any wires? It is Wire in, Wire OR Wireless out.
After you get the router working then go to Dell and get the other drivers by entering your service tag number.
