My application required a phone link. Therefore this hardware was incorrect. This was my fault as I should have checked prior to purchase of this (ISP recommended) equipment. I returned the unit and purchased a separate router unit (Netgear N900). The ISP provided a new modem. Unfortunately, I still have a separate modem and router but everything works fine, now. My ISP recently changed over to new software which precipitated the need to change (update) my older router . The service tech recommended to keep the router and modem as separate boxes.
