I've got the same router. Plug the wireless card into the laptop and load the software do it, whichever way round it says in the instructions.I use a cable modem so that's the only difference to your set up. (My modem is in a cupboard with the router attached), once they are connected, switch them on and allow to sort themselves out. Then all I did was to switch the computer on and let it find the wireless network. You can then configure the router over the wireless network as required. I have two computers connected this way and occasionally a laptop. No computer is directly connected to the router as the instructions say and have no problems apart from an annoying flashing light on the router which I can't see now as it is in a cupboard!
