i want to connect my new wirless router to my DSL modem so I can use my laptop at the same time wirelessly. If the DSL modem is the uses the pc (Vista OS) for a fire wall. will I have to confugure the new router to the same properties as the DSL modem ? I thought I could just connect the DSL modem to the router, then router to PC via the one of the 4 wired pc connection points, then use the wireless card on the laptop to recieve the WI-Fi signal. but the laptop isn't seeing a wirelesss network? any advice would help.
