Can it replace the one supply bi XFINITY? is it also a Modem?

This is an enterprise device. IF you are not sure if it is a modem or not then you would far far better off purchasing a consumer level product. You are not going to understand how to even log in to this device. It is a full power router with expansion slot space. You can install various EHWICs of your choice such as a cable modem module, several hundred dollars, wireless etc.... you would be far far better off purchasing something that is consumer level unless you have formal training in Cisco products and IOS operating system.

No, this is a router, you need a modem in front of it. Google xfinity supported modems. If your not getting voice from them I recommend the motorola surfboard

I don't know if it is compatible with Comcast but yes it is both a router and a modem.

I can't say for sure. I checked Cox's site, and they list only a handful of devices, and DON'T list this particular one (Linksys DPC 3008-C) I bought, as an approved replacement (although, that doesn't mean it won't work!). Many cable (ISP) providers want you to either rent or purchase your equipment from them, so rarely do they include models that they DON'T sell themselves. My apologies for not having a more definitive answer, but I have Comcast....an entirely different animal altogether. As much as I hate to say it, you may have to call their tech services dept., wait on hold for an hour or two, before you can actually get an accurate answer. I can't say for sure.

Probably not. I bought one from an Amazon seller and my cable provider (Cox) refused to provision it. It seems you can buy data-only modems anywhere and they will accept it, but they will only provision voice(telephone)-data modems that they sell. You are most likely stuck with buying one from your cable provider. If you really want to try I will sell you mine for half price!

Yes it is, no need for both modem and router. A free outlet and more space on top your your desk!

I am using this modem since last August. It is working very well with comcast (xfinity) internet service.

This is a modem. I also have purchased a Router. I have xfinity cable, internet and phone.

No. This particular modem is for HSI data only - as noted in the description. I believe the Ubee DVM3203B is used for telephony, but see the following Comcast/xfinity URLs for supported devices and their approved uses: http://mydeviceinfo.comcast.net/ http://customer.comcast.com/help-and-support/internet/list-of-approved-cable-modems/

Yes (as long as the xfinity modem acts as a router). I have my modem connected to my router. Then I have an Ethernet cable from the router plugged into the powerline adapter. I then have 7 other poweline adapter throughout the house feeding wired devices in different rooms.

No - it is a cable modem. Would be the first device in a home / small biz setup. Will need a router to attach to. Recommend a NetGear N-Series device.

That I don't know. The reason I went with this one is because this is the exact modem that Comcast uses and I wanted to minimize any transfer problems. the modem I had before this was Aria which Comcast also uses. If you go with one of the other modems, just make sure it is supported by Comcast before purchasing because not all modems are and I didn't feel like doing the research. (also just bec an item is more expensive doesn't mean it's better. however keep in mind that this is a modem only and NOT a modem and router in one). -Take Care.

No! this modem is for DSL services operating off of your home phone service. You need a cable modem for Time Warner Cable services

No this was a replacement for a modem on comcast. I had been renting with them for a long time at $7.00 a month. They gave me a hard time to get it installed, but once installed, it works great. It is the same brand and unit that I was renting from them.

No this does not replace a modem. And if this is connected to any Verizon that is attached to your TV, you can not get rid of their device since all DVR function goes through it, simply attach this router to the modem.

I highly doubt it. This is for DSL service, which Comcast does not provide. Look for a DOCSIS 3 modem.

I don' know , you should ask the seller, but yes, it is modem- router in one unit.

I have Comcast and have been happily using the SBG900 modem for years. I'd say whomever you're talking with at Comcast down't know what they're talking about.
