i have got an arris tg852 modem that i want to hookup for wifi. there is a modem in the main room and i have no ethernet cable
 
Can you please make this a little clearer? Do you want to replace your modem with said router? Attach the router to the modem?
Is anything currently attached to the modem? Do you currently have any device that uses the Internet and, if so, can you describe the setup?
Thank you
