Any problems hooking up to Comcast cable? Read the review of the 24 inch and it said some cable companies don't support it.

I do not have comcast, but the upstar would not hook up to my cable at all. I had to use the remote that came with the TV to change channels and the cable remote to turn it on. Worst sound that I have ever heard on TV or any thing else.

I haven't had a problem with mine. Works great use it on Comcast in NE Florida. If I have connection issues usually on Comcast end.

seems to be working now but Comcast had a lot of difficulty adding it to their system. I would try a "ubee" instead since that seems to be the make they are distributing. But I have no technical training and have no idea how it might perform.

Not true.....I bought mine through Amazon.com and they were a better price than Best Buy. They back up their warranty as well. I also have Comcast and it fits nicely and I have not had any problems. Love this modem.

Update 02/02/15 -- TM822G NA-0 is the model I have and it works fine.I purchased the TM822G in April of 2013. This model has worked just fine since day one. I called Comcast, they got it up and working with Internet. I had to call a different number to get it provisioned for my phone but that took about 10 minutes and from there I was up and running with cable, internet and phone. 1.5 years later and I haven't had a single issue. I have the Extreme 50 and usually get better than that throughput.I always recommend that people read through the Amazon reviews, there are a couple of post that tell you EXACTLY how to get it provisioned correctly.

I don't know. I'm guessing you can check with them? That's how I knew it was Comcast compatible.

I have exaclty the same problem. I've had comcast at with this tv, and wide screen option was availabe at my old address (using HDMI cable) but at my new home, it's now grayed out. I believe it may have something to do with the comcast reciever. Can not find a FORMAT option on my cable box remote. It does have a position picture adjust option under the menu but that does not solve the issue as it just helps you move a slightly left ,right, up .or .down. I'm geting a 32 inch picture on a 53" TV. Totally SUCKS!Samsung forman suggested

Hi, this model is on the Comcast approved equipment list. I'm using Comcast too, but currently I'm experiencing difficult time with this setup. It is not consistent/reliable in the speed for some unknown reason. It can be very fast when it works properly but later the speed will drop almost to a halt. Very frustrating and have called Comcast multiple times, but as of today, the problem still exists.

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.

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 bought the home unit and two others and have no problems. Depending on your house wiring, etc, quality of your signal into your home. Using Comcast as example, 5 at most, depending if anything else in on your network.

No, comcast is cable, unless Comcast is offering DSL in your area, it is not compatible.

Modem just arrived today and tried to connect with Comcast. They said they do not connect model numbers DPC2100.

ONLY if this specific model is listed on Comcast's Approved Modem List. From what I have read, they have changed their hardware and support networks to specifically exclude "non-approved" modems. Their tech support people may pass you around but their hands are tied.
