I have Comcast TV, Internet and Telephone. I currently have a RCA DMG 536 Modem. What modem can I use to upgrade to 3.0.

I have the same services from Comcast and was able to switch to (a used) tm822G which came with a new back up battery. It took me a while to get a well trained support person to undo the previous mistakes of an offshore person who royally screwed up just about everything they could. Once the phone and internet services where switched to the new modem properly I was able to use my own modem but it took several months and two trips to the local Comcast office to correct the billing. Initially I was told by a high level (I think they call them second tier) tech support that Comcast would not be able to switch me to my own modem because they would have to reflash its firmware and once they did, they would own it. So you might hear a lot of official-sounding statements to discourage you from switching to your own modem but going by my experience, it takes a bit of persistence but it's doable.

The Arris TM822G works like a charm and it's beloved by Comcast techs. Excellent speed and processing.

Your statement also describes my situation of have Comcast as a provider of TV, Internet and telephone. I bought and have successfully used the Arris TM822G Touchstone® for a number of months now. I did have to have a Comcast technician come out and do some final installation before the telephone would work.

this is exactally the same modem that comcast uses. For the price, i bought 2 of them. Replace the comcast modem and start your pc, the net will re-set you new modem.

I was able to get it working with Comcast relatively easily. if it doesn't connect for you, don't call the activation line. call the generic tech support number for comcast (1-800-comcast?), get to the internet support and have them connect the modem.The activation department will tell you this modem isn't supported, but the internet support people don't care.If you have a good tech, they should call the activation department to get your phone lines transferred and all should be good.

As of 11/8/10, the list of approved cable modems for Comcast lists this modem as approved, but the End of Life date was 5/8/2009. Apparently the modem was supported in the past, but it is now not supported. They want you to get a newer model, probably because they don't want to respond to complaints when the older modems don't work with the newer, faster technologies.

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/

If you call them they will happily tell you which modems you can purchase that are compatible with their system. Also, be careful if you buy a second hand modem online, they are often equipment that belongs to the cable company (Comcast, Cox, Time Warner) but were never returned (by deadbeat customer who left unpaid bills and pawned the equipment), they have a record of those serial numbers and they cannot be used for another account.

It will work just fine but it is getting past the tier 1 tech support the real issue. Any DOCSIS 3.0 modem will work but they go by the book and say it won't. You can request to be sent to a higher tech support or just tell them it is a "SB6141" model. All they really need to do is register the "MAC address" on the bottom of the modem and you are done. I already already installed over 9x SB6180 modems.

Attached is a link for compatible modems used with Cox Internet Provider http://ww2.cox.com/residential/support/tv/article.cox?articleId={b2ec95d0-7ef9-11df-5590-000000000000} Within this link is a list of compatible modems Zoom lists a few..Zoom 5341 Premier (Premier Plus, where available) 5341J Note: Click on the link above for market compatibility. Ultimate, except in markets noted 5350 (WiFi modem) Ultimate 5352 (WiFi modem) Ultimate Legacy DOCSIS 2.0 devices (no longer recommended) Cox recommends all customers use a DOCSIS 3.0 device from the list above. There are a limited number of DOCSIS 2.0 devices that will continue to work on the Cox network, but if you are on Preferred, Premier, Premier Plus (where available) or the Ultimate tier, Cox strongly recommends that you upgrade to a DOCSIS 3.0 device for the best consistent speed experience. Future speed increases may not be achievable with these devices I think it would be compatible but you may want to check with the Cox provider just to make sure.

I don't know about comcast. I am with TWC, Cg3000d is not in their list as well, only CG3000Dv2. However, I can use Cg3000d to get online with TWC, in Chapel Hill. I think CG3000Dv2 is second version of Cg3000d, but still works very well for my case. May be some comcast users can give you a confirm answer.

NO.. Actually I sent this modem back. I did replace it, however, with a "TELEPHONY" modem that is just like the one I was renting from Comcast. I didn't realize my error in reviewing this item until after I hit ENTER. sorry

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.

Any opinions yet fellas?.... I have the same question, after considering to bail on Qwest DSL and DISH, and change to Comcast Triple-Play for Phone, Highspeed Internet, and Cable.

Its just a modem - you'll have to get a separate router. Unlike what comcast provides which is a dual purpose modem/router.

It depends. I actually work for Comcast and was unable to get this modem provisioned. After some digging and a chat with a contact I have at Arris, it seems that Arris makes several variants of this modem. They are not supposed to be sold to retail consumers and each variant is specific to a particular ISP. In my case, I was shipped a model TM822G/CV. That is designed to work with Optimum and that's why Comcast couldn't provision it. The correct model for Comcast's network is TM822G/CT. There should be a sticker on the back next to the coax connector telling you exactly which variant you have. I'm going to attempt to return mine, though I bought it 6 months ago and have only now had time to fiddle with it. It's pretty irresponsible of the vendor to not disclose this so it's anyone's guess if you'll get the correct part for your particular ISP and they don't ask you which one you want.

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.

Once your modem is connected to the cable, you should be set. But if it isn't recognized (and you'll get an error message if this happens), then you might need to call Comcast. In that case, the tech you talk to should be able to recognize the modem and set it for you.

They both support docsis 3.0 so I don't think there are any kind of differences between the two.In fact the modem was exactly the same as the one Comcast were providing last year and I had to give them the serial number so that they know this is not a rental.
