This is the list I was directed to. How am I to know which one is right for my service?

 

You have got to be kidding.

Re: approved modems

It's pretty easy. Just move the selector to the speed tier you have and it displays the modems that are approved.

What speed tier are you actually subscribed to ? With that knowledge you can decide. To simplify, lets say that if you have the Blast speed tier or anything faster you need to use a DOCSIS 3 capable modem. Anything slower than Blast you can use a DOCSIS 2 modem.

Didn't see your reply before I posted nerd.  :smileyplain:

Re: approved modems

So since I have the Blast! speed tier I need a Docsys 3.0 modem? EG, I've seen you post similar info in the past; how do I get my modem upgraded to match my speed tier?

 

I have called Comcast Support three separate times in the last year and a half and asked for a Docsys 3.0 modem in order to support Blast!, only to be told that my current modem is fine and supports Blast. I currently have an Arris TM402P modem, which is ancient.

 

If Comcast won't allow me to upgrade to a Docsys 3.0 modem, am I expected to purchase my own and install it? Is that even permitted in my area?  (SE PA)

 

Thank you,

 

Jim

Shame on them. They should practice what they preach and supply you with the recommended modem for your speed tier.. That said, you can purchase and use your own D3 capable straight modem anywhere in Comcast's footprint as long as it's not an eMTA/telephony type modem and is on their "Approved Modems List" here;

 

http://mydeviceinfo.comcast.net/

 

 

 User owned eMTA's become a bit more complicated.

Even when I had an appointment set up to exchange the modem the tech refused to change it...So I called in and got a self install gateway device. Most people here, would not recommend a gateway device, but once the router part of the device is bridged, it's fine.

 

The problem is there are different speeds for Blast! in different markets...16/2, 20/2 which work ok with a D2 modem. If you get upgraded to 25/4 as I was, you will need a D3 modem to get the full benefit of it.

 

The other choice is buying an eMTA device from BestBuy with a Comcast Connection center. (since you have an Arris 402)

 

If your market does indeed alow that!

Re: approved modems

EG: But I have an eMTA now, since I do have telephony from Comcast.  (Emphasis on telePHONY??). Don’t I need to use an eMTA unless I drop the Comcast phone line, which would actually suit me just fine.

 

Thanks!

Re: approved modems

Paranoid, the last email notice I received about my Blast! speed said:

 

"On or about October 1, 2010 your Blast! service will be faster than ever with download speeds up to 25 Mbps with PowerBoost®. And upload speeds that are twice as fast."

 

So I guess that would be 20 up and 2 or 4 down (ignoring the Powerboost adder Comcast loves to add to the speed tier).

 

Anywhere else to purchase one? I don’t even walk into Best Buy stores anymore.

 

Thanks!

EG recommends ShaperProbe to test your speed (shows what you are provisioned at too):

 

http://www.cc.gatech.edu/~partha/diffprobe/shaperprobe.html

 

(run as administrator for win7/Vista)

 

Here's mine:

 

DiffProbe beta release. October 2009. Build 1002.
Shaper Detection Module.

Connected to server 74.63.50.40.

Estimating capacity:
Upstream: 6449 Kbps.
Downstream: 36295 Kbps.

The measurement will take upto 2.5 minutes. Please wait.

Checking for traffic shapers:

Upstream: Burst size: 9888-9968 KB;
Shaping rate: 4256 Kbps.

Downstream: Burst size: 19394-19883 KB;
Shaping rate: 26618 Kbps

 

That shows I get 36/6 with powerboost, although it's actually provisioned at just over 26/4

 

When mine got upgraded I noticed the download speed was erratic, anything between 20 and 30 with powerboost using a D2 modem.

As soon as I connected the D3 modem, the download went to 36 with powerboost, and has remained pretty solid ever since.

 

As for buying an eMTA, up until now the only eMTA available for sale is the Arris TM722G Only available from BestBuy with a Comcast Connection Center or rep in the store, and this usually involves a paid tech install. The eMTA is about $150. Not all markets allow customer owned eMtA's.

 

Hope that helps!

They should supply you with a DOCSIS 3 capable eMTA like an Arris TM702G or TM722G or whatever they are using in your area.

 

In some areas the "Blast" tier is actually being made to be 25/4 sustained.
