has this modem been approved by Comcast?

I just bought this modem on Amazon and after screwing around on the phone for 3 days with the people at Comcast a Comcast tech was called and he was not able to have it recognized???. I was without phone and Internet for 3 days and let him install one of their modems temporarily. I don't understand this, are they doing this in purpose to rent there stuff??? Comcast is also charging me $39.95 for the tech.

NO! I bought this thinking it would be approved. Yes, it does work, but I got less than half the speed I was supposed to get the RETAIL version of the TM822 is NOT approved for Comcast. I spent over an hour figuring this out so learn from my time!

Yes. I work for comcast and purchased this one. It is great. You save money from the rental of equipment. If you are not even planning on getting phone, it is still a good choice to get this one because if you roll into a triple play you would have to pay rent for a similar phone modem.

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.

Yes. That is why I bought it. A comet tech even check it to be sure it was installed properly... it was.

It is on the comcast list of approved modems. However if you do not subscribe to their phone service you may have some complications getting it installed. I do not have the phone service and the comcast technician who came out to set up my service had problems getting it set up when he call it in to HQ. He was refered back and forth between the internet and phone deparments. Eventually he had to go higher up and do what they call a Grand Slam (a manual install). They got my modem registred after about 30 minutes of getting kicked around. The modem is great and works fine. Comes with it's own battery backup. It is on the comcast list of approved modems.

K Yes. I think the details should be on the bottom of the modem. I was able to provide Comcast with all the details they asked for.

I know the description says for Comcast only, but I purchased this modem in January of 2012 and plugged it in to Charter Cable and it has been rock-solid ever since. I probably should add the caveat that my subscription is for the 60MB speed level, so it's possible that this modem won't work properly with higher speed packages. I believe that the Comcast-only declaration is because this modem doesn't appear in the "approved modems" list for the other ISP's, but that's just my guess.

I don't know for sure. I am using it with Time Warner. They had a list of compatable MODEMS and this was on the list. I would suggest you ask COMCAST. I hope it does as Time Warner is supposed to sell out to COMCAST.

it will and it wontI have this modem, when it works its just fine, but i have to reboot it at least once a day. I complained to comcast and they said to buy a modem which was DOCSIS 3.0 --- this one is only 2.0

It's working with Comcast for me at this moment, has been for two months now. Comcast does have a new speed standard, called DOCSIS 3.0, and this router is DOCSIS 2.0. Regarding this Comcast says, "...DOCSIS 2.0 modems will still work with our speed tiers (except for Blast! and Extreme 50), but you won't experience the blistering fast speeds now available." However, "blistering fast speed" is more in the mind of the marketing department than in reality. Once you have around 5megs of download speed (Comcast provides more than that) "blistering" becomes unnoticeable. Still, if you have Blast! or Extreme 50, apparently this modem won't do the job.

I'm not sure. In my area Comcast uses cable to provide internet service and this modem is for ADSL, not cable. Here's a link to the user manual: http://www.tp-link.com/Resources/document/TD-W8960N_V3_User_Guide.pdf

It is currently on Time Warner's approved modems list (it wasn't when I checked last year).

I use this modem with Mediacom at my beach condo. I purchased a ARRIS CM820 modem to use with Comcast at our primary house. I recommend purchasing a modem from the Comcast approved list on their website. My ARRIS CM820 works great with Comcast.

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.

Yes it is, but make sure your ISP supports that model because Comcast decided they dont. So I had to return it because of that.

I've had this modem for a long time and I have Comcast/Xfinity. However, I just looked at the approved device list on the Comcast website (http://mydeviceinfo.comcast.net/) and the SB5120 is no longer listed.

Comcast is not a big fan of when you have your modem. Yes, it was compatible, but Comcast after a few weeks stopped working and wanted to charge for technical service help. My advice... run while you still can (from Comcast, that is).

Yes it is but you have to make sure once you get it you call comcast and register it or it will not work properly. That is with any personal modem though.

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.

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

It will with no problems. You don't need a new modem. I have Comcast's older modem with of course a router and it works perfectly. Comcast sounds like they are trying to make you pay more money for a newer modem which is not necessary.
