I need help I have a new Xfinity wireless router and would like to also use my old Linksys WRT160N router as the xfinty one frequently drops. I would like to connect my old Linksys WRT160N router to my new Xfinity wireless modem and have access to both. But I can't configuer the Linksys modem using IP 192.168.1.1 - it won't come up on any of my computers.
