A:AnswerYes. The cable from a cable company (such as Comcast) comes into the modem, a cable runs from the modem to a router, and the router broadcasts and wireless or wired signal throughout the house. I have a NETGEAR R6700 Nighthawk AC1750 Dual Band Smart WiFi Router and the combination works great.
A:AnswerThe CM500 is not a DSL modem nor does it have a DSL port. The CM500 only connects to internet service via a coax cable from a cable TV internet provider.
A:AnswerI use it with my xfinity and have not had any problems with it. My son plays games and streams movies with out any problems. I use it for school and research.
A:AnswerYes I have this modem connected to COX Cable along with the Linksys - VELOP Wireless-AC2200 Whole Home Wi-Fi System and the combo works great. No issues working with COX Cable just call them and give them info on the new modem.
A:AnswerYour speed at the modem will be what you contract with the ISP for. Normally it can be perhaps 5% to 10% better. Away from the modem other factors prevail such as your router, the device you are testing, the environment.
