Not new but used - I was unable to gain access to the Internet and had to take it into Xfinity store. While there they came to the conclusion the address had already been assigned which means this unit was not brand new.

Netgear Modem for Xfinity - This modem was not able to connect to Wi-Fi. I tried two different set of routers and did not work. Finally I switched to a different modem (ARRIS) and everything worked fine.
