A:AnswerYes it does! I have Comcast as my provider and haven't had any issues so far. Also get a router if you don't have one since this isn't a router/modem combo
A:AnswerThis is Not a voice capable modem. Voice cabaple modems only come from your provider. Here is a better question, why are you using their voice system when you can get VOIP for much cheaper and better equipment?
A:AnswerNo, its a dedicated modem hence it has no wireless router functionality. You have to add your own wireless router to get either a 2.4 ghz and/or a 5 ghz signal. I added a Orbi mesh router on mine and it had been working well with Comcast as my provider.
A:AnswerNo, this is a cable modem only, not a router. It is designed to connect a cable network to a router not to extend ethernet to another location over coax.
