Is your item truly Model # DDM 3513 Docsis 3.0? And, can it be returned if it will not connect to Comcast Network?

This is the DDM3513 - new, in box, same product sold directly to Comcast. It won't have any issues connecting with the Comcast network. Standard Amazon return policy applies - 30 days no problem to return.

If you don't buy it from Comcast/Charter, and have an issue which is hardware related, Ubee will not assist you in any way. They only deal directly with ISPs. Their web page refers you to go back to your provider.

I am not too sure. I had one of the motorola DCT700 that I ordered for my cable company, but it was for comcast only so I resold it. I am sorry I wish I could be of better assistance.

Your ISP only needs the MAC address of the modem. Comcast also asked for the Manufacturer, Model No. and Serial No. I believe they just want to make sure it is compatible and if there is any issues what specific unit is giving problems. This unit has worked flawlessly on the Comcast network.

When I called to connect it, I was told that the modem was already registered with a Comcast account and I couldn't use it. Luckily, I called back and got a different technician who could connect it. So far, the device has been consistent and I haven't had any problems, but I almost wasn't able to use it. It might depend on the technician as to whether or not they'll connect you with service...Just a word of warning when buying used. It would have been nice to know that ahead of time.

I just purchased this to replace my Comcast modem, based on the reviews here. Unfortunately, I was unable to connect--first, rejected by telephone with Comcast. Then I followed in instructions listed by another review and tried to connect via the internet. Rejected again. I don't know whether to return this unit or keep trying until I find a Comcast tech who will connect it. I am so frustrated with Comcast and how we are held prisoner by them.

Unfortunately not. I returned the router and bought a Technicolor model from another supplier for $169. same as the model Comcast is renting.

I really cannot answer since I purchased my DGND3300 after changing away from Comcast. Sorry!

I programmed my 880 to work with it. Device=PVR. Manufacturer=Comcast. Model=Xfinity X1. Works beautifully.

I would tell you but it seems like a waste of time when you already know what to do. Sorry just giving you a hard time. I actually didn't do it. Comcast came by on a service call and installed it without me asking them. Would have been ok if they had done what i actually asked them.

DOES NOT WORK WITH COMCAST ANYMORE. I just recieved this modem and called comcast this morning to register it, the tech support guy said that they JUST stopped supporting this model. I hate Comcast.

Yes. Mine seems to work with a Comcast HD receiver. And I even have a splitter going in between.

Yes this works fine with Comcast and Charter (or any cable internet company), but you can't use it with their telephone service (so if you sign up for internet and telephone you have to get a different model). This device is an all in one with included WiFi, which makes it a great small device that covers all your bases.It isn't DOCSIS 3.0, but that doesn't matter since Comcast speeds don't even reach the capacity of DOCSIS 2.0

Had similar experience with Comcast, although the TM822G technically will work on their system they would not activate equipment not on their inventory

I'm dealing with this now. I called Comcast, gave them the MAC and serial numbers, and they said this modem is not compatible. Their list of compatible cable modems at http://mydeviceinfo.comcast.net shows the NetGear CG3000DCR and CG3000Dv2. So now I am trying to upgrade this CG3000D to CG3000Dv2, but it does not look good. Waiting for NetGear tech support chat as I write... I might need to return this cable modem, and order one on the list. More later... NetGear's answer: No. See http://kb.netgear.com/app/answers/detail/a_id/24324 DO NOT BUY IF YOU ARE A COMCAST CUSTOMER.

Hey this is Nina I am not sure but give it a try. Plug it in the modem and see if it works and it not, plug it into the wall using comcast service. It should work either way. Nina

No you need DOCSIS 3.0 Cable Modem. This is a DSL modem. You could plug it into a cable modem and use it as a router only as it has a LAN/WAN port.
