which type of modem is needed?

My dad is currently paying $7 for the rental modem and wants to buy a modem to stop paying the monthly fee etc.

He currently has some very slow speeds like around 1.5 mb download or something but since he recently put netflix he is planning to upgrade his speed to around 10mb, or whatever comcast has closest to that.

First of all: is a Docsis 3 needed for 10-20 mb speeds? If yes, could you please recommend a cheap one (in price)? If no, even though its not needed, do you still think he should get it docsis 3 to future-proof?

Thanks.

no a d3 modem isnt needed.....helpful, but not needed....it can help ease congestion and stabilize your connection...

dont know what you think cheap to be, but $70 for a zoom d3 modem..
seeing as a older surfboard is $55 i think its a good deal...

Just be careful because a non D3 modem most likely wont support IPv6 which that in and of itself is an improvement towards futureproofness.

Sounds like he has the economy level, here is the Comcast approved modem list »mydeviceinfo.comcast.net/ any modem on it should work fine.

If you have Comcast digital voice service you'll need to buy an emta to avoid the $7 modem lease charge. If it's only internet service, than practically any D3 modem on the list will do the job.

You didn't specify whether your dad is getting just internet, or internet and voice.

If he gets both internet and voice, it gets a bit convoluted, as there is a very limited "own your own" path with eMTAs. Currently, the only approved eMTA modem self-owned, is the Arris TM722G, and only if purchased through a Best Buy with a Comcast center. It may or may not be all that cost-effective a move (the TM 722G goes for $149...then add on Comcast's set-up charge)

On the other hand, if your dad has internet only through Comcast, it gets a lot easier!

Your dad is probably going to want to upgrade to the "Performance" tier based on desired download speeds stated (although Netflix can run just fine on Performance Starter, which is 6Mbps down).

Although a Docsis 3.0 modem may not be mandatory, I can think of no compelling reason to even think of anything less.

For example, you can nab a Zoom 5341J for $89 or less (you can find them cheaper on-line). It is a good, current Docsis 3.0 modem that will give good service and pay for itself after the first year over renting. there are other Comcast approved D3 modems that are just fine as well.

As EG points out, even if you do not need a Docsis 3.0 modem based on speed alone, the ability for Docsis 3.0 to bond 4 to 8 channels, will maintain more consistent throughput than an earlier Docsis 2.0 or 1.1 modem, which is particulalry good news for streaming video!

My only caveat: Do not try to save a buck by buying a modem that you do not know is new. There are used/stolen modems sold on ebay and such, that Comcast may not provision...IMHO, spend a buck and get one from a trusted retail source.

tell that to......

said by AVonGauss:

I'm not sure why you're under the impression it does not, but the SB6120 should work fine when IPv6 is deployed in an area - it is even listed as compatible on the Comcast list.

The 6120 works great with IPv6.

Sorry for not giving this info earlier. He doesn't have voice, he only has internet and cable (although he wants to remove cable now that he has netflix but I think they raise the price of Internet if you remove cable so it may not be worth it, we have to look into it)

So since he has no voice, I'm glad to hear it's simpler with the modems. The Zoom recommended by gar187er goes for $70 at Amazon and it's new (following peteC2 advise) and at a very good price point. I think we will purchase that.

Thanks so much for sharing your knowledge, we appreciate it.

Also, where could I find the prices of the different internet tiers for existing customers? All I ever see are the 6 months new customer specials etc.

huh? I don't know what you want me to tell them because all three of us agree that D3 modems support IPv6.

Ah...yep...but then of course the SB6120 is a D3 modem (even if you call it a "6120")...just saying...

LuisRodg, I would recommend calling Comcast. One of the confusing things that I discovered when switching from dsl to Comcast, there are a number of different offers based on your location, and you will probably wangle the best deal by giving them a call rather than counting on their web site.

I did not even realize that I counted as an "existing" customer because I rent a HD box from them (the rest of my cable bill is paid by my apartment complex). In fact, it may sound paranoid or at least fussy, but I called a couple different times, speaking to different representatives before settling on the best deal for my situation.

Yep, $7 a month either way. The eMTAs may or may not be as easy to get. As I mentioned, initially they sent me both a D2 eMTA as well as a D3 modem for intermet. I did get them to replace the two with a D3 eMTA.

Keep in mind, they are supposed to charge you shipping ($10), but they waived it for me. They will charge you the $10 for provisioning the new modem.

go for a D3 modem just for better connection stability and being ready for IPv6.

and as stated before in the thread, Do not use Ebay or Craigslist. Yes going to the bestbuy or Newegg/Amazon costs more but you will know then it is new and has never been on an account.
