We have Comcast for cable and phone so we have a roouter that has a phone jack in it- where the phone line for the phones plugs into. Well I am changing to wireless. I can plug the phone into my wireless router but there is nowhere on the modem for the yellow- USB plug cable to plug into on the modem. do I need to get a different modem from Comcast or is there an adaptor plug that I can use that will allow me to plug the usb wireless plug into the phone jack on the modem?
