Hi there! My name is***** am a computer professional with over 15 years of experience with both Mac and Windows. I'm sorry that you're having this issue. It would be my pleasure to help you resolve this. What type of internet service do you have? Typically you will need to connect the wifi router to the modem with a network cable and then connect your computer (s) to the wifi router either with another ethernet cable or wirelessly, Do you have the cd that came with the modem?
