DSL modem/wireless router combo for AT&T? Is this a crazy idea? will it work? I just killed my DSL 2wire modem wired connection by trying to add a wireless router. Attempting to bridge, I changed a setting and now I cannot even reach the modem with the computer. so, since I am in the middle of hassle anyway, I am considering just replacing this old (6-year-old) modem, and replacing with combo DSL modem and wireless router. Has anyone done this? suggest a model?
