Just replaced old modem with a new style at the Comcast Store. Came home and reattached cords/cables - now I have no phone dial tone. Didn't have a problem with the old modem. Made no other changes to the system.
Tried to use 'chat' mode - couldn't figure out how to work it, and don't have a phone to use to talk to anyone.
Got NO documentation with the new modem so don't know how to reset it (or if that would help).
P.S. - would love to identify the new modem, but I'm not sure how to identify it.
