Blast

Just upgraded to Blast today and have since seen on here, that Comcast recommends DOCSIS 3 for Blast.

 

I was issued with an Arris 502G which of course is DOCSIS 2.

Called Comcast and they say that DOCSIS 2 is ok and there is no need to change it.

 

So which is it? Surely if DOCSIS 3 is recommended, then that's what I want.........Help!

Re: Blast

I have been through the same thing, the official response is D3 is recommended but not mandatory as a D2 modem will supply Blast! speeds.  I couldn't get my TM602G eMTA replaced either, but I am getting full Blast! speeds without problems.

 

With the increased rental fees, I'm going to purchase my own eMTA which will be D3.

Re: Blast

I don't get it then, if that's the policy, the web site should say that DOCSIS 2 is ok....Just causes confusion!

 

Thanks Jay.

Jay. Did you confirm that your particular area will allow customer owned eMTA's ?

Yep, the Best Buy on the corner has had them on the shelf since they came out last fall, just not big sellers.  I have chatted with the Connection Center sales rep on multiple occasions, and try to send sales leads his way.

 

I was holding off because of traveling, but now the rental went to $7 so more incentive to do it.

Re: Blast

I have had Triple Play with BLAST for over 3 yrs and have NEVER gotten the speeds (esprcilly upload)  I'm paying for.

 I called Comcast last week with a question and happened to mention my speeds. The Rep told me that because I have phone service with them it requires a special modem. She also told me that the modem I have will NEVER allow me to get the speed asvertised for Blast, it's physically not capable of handeling it.

 

So for 3 years I've been paying for BLAST with them knowing very well the modem I have could not handle it.

 

I'll be calling them today and feel I'll be on the phone until they close........

What is the exact make and model number of your modem/eMTA ?

Re: Blast

***docsis 2 won't break 12 Mbps. Don't pay for 20 when your docsis 2 modem CANNOT obtain those speeds***.

 

 

just go out, spend some money get a nice docsis 3 modem ( I have the motorola sb6120) got it from bestbuy. I have blast (20 Mbps) and CONSTANTLY test out @ over 30 Mbps.

 

Technically Comcast should not sell customers Blast! if they have a docsis 2 modem, any good tech support or sales agent should know this or at least ask you what modem you have before selling you something that your equipment cannot achieve.

 

 

As for the person with the "special" modem for the phone/internet do it all it's an easy fix again if speed MATTERS to you. Go out get yourself a docsis 3 modem, run a splitter and have Comcast provision your modem for you, they can do it over the phone so long as you provide the mac ip for the modem (on the sticker with the model #). If you don't want to run a splitter because having a phone modem and a cable modem and possibly even a router in the mix causes interferance, use a different cable outlet. 

 

Besides, your internet modem and/or router should be very far away from your phone being that most people have cordless phones in their houses and cordless phones along with other appliances (ie- microwaves) interference with bandwith and lastly ensure you set up a password and secure you network if you have a router.  It is VERY EASY to do and i'll provide a link for an easy to follow along step by step.

That is not true technically as a single D2 downstream channel can provide a maximum usable throughput without overhead of 38Mbps, although CC does recommend that a D3 capable modem is used for the Blast tier. It is a win win for both the subscribers on the shared segment and the provider as far as peak time capacity/congestion and consistant speed benefits are concerned. There are channel failover benefits to be had as well.
Also, there are indeed D3 capable eMTA's (combo phone and internet devices) that can deliver their Extreme 50/10 tier so they can easily deliver Blast.

Re: Blast

Hi I have comcast internate at home.    Would never use their phone though.  I use OOMA which costs me 10 bucks a month.   I also pay 5 bucks a month for 500minutes to Australia land lines so my wife can call her family.    Voicemessages automatically get emailed to me as mp3 so i get check my voicemail whereever I am in the world.  I work overseas every 2nd month.     I am looking at options at the moment as the mongrels (comcast have increased my price per month from 45 to 63.)  I can get 25MB link from Centurylink for 30bucks a month.   With OOMA and Netflix and FTA Digital will be paying less than 50 bucks a month.  If need be I can also use on demand with Amazaon via one of my laptops plugged into the tv via HDMI.
