Re: [Speed] Northeast speed changes coming.

The Lynksys is not Docsis3.0 Compatible. ALLor almost all of Comcast is now DOCSIS3.0 enabled with multiple downstream Bonding to achieve the higher speeds.

Estimating capacity:
Upstream: 10670 Kbps.
Downstream: 53175 Kbps.

Is that 50mbps down or just powerboost?

There is no more powerboost on the Blast Tier.

Oh, yes. Your modem very old. Docsis 2 if memory serves. If you buy your own modems, I recommend this one:

»www.amazon.com/Zoom-DOCSIS-Cable···le+modem

Many who have come here asking the same question have bought one with great results. Plus, it's 8x4 vs the 4X4 that you get with the Motorola SB6121. The Zoom modem I linked to is also not only better then the SB6121 specs wise, it's also cheaper.

THanks, order a J revision, I guess I'll have to chug along at 34mbit for the time being

Yes. 34 megs ain't bad, but getting the full 50/10 or better Blast! gives is better. Also, what router do you use? You might wanna think about upgrading that too, depending on what you already have.

My router is fine, got a D-Link DIR-655 (not the best but it works fine)

Thanks for your help.

You're welcome. Be sure to come back and post when you get the new modem, so we can drool. If you have any problems, come back as well. Good luck, my man.

I'm jealous of all you guys with the upgraded speeds. I've been rebooting daily, no luck at all. Then I checked and saw we were on performance, so I upgraded to blast. Absolutely no change in speed. 25/4 with performance, 25/4 with blast. I even had the modem re-provisioned a second time last night.

I'm in New Castle, Delaware. About 10-15 miles or so south of someone from Wilmington who posted they have the upgraded speeds.

(I am not in Newark as my userinfo suggests.. How do I fix that?)

Even my VZW 4G phone gets faster speeds, but really only in one town - I've gotten 33/9, which shocked me.

I'm in the same boat. My LTE phone gets faster speeds then my blast connection at times, at home... Not so much the download speed but the upload is a good 8x faster.

It's a little sad when your cell phone's internet is faster than your cable connection.

agreed, I'm from the same area as you are and my 4G speed tests faster. Which brings me here, has anyone gotten those higher speeds yet? I'm looking to call them tomorrow as its been a week and see what the hold up is.

The upgrades are only for the northeastern markets right now. The rest of us get screwed.

I just got the upgrade here, at least on the upload side. I currently have Blast and my download is still at 30mbps. Upload has doubled though to 10+ mbps. Modem (TM502G 3 in 1 Arris) has been powercycled. Any ideas?

Perhaps get a DOCSIS 3 modem? You aren't going to get ~50mbps downstream with your current modem.

Agreed. You need to get in touch with Comcast and have your modem swapped out for a Docsis 3 modem. Go here: »Comcast Direct and talk to Comcast Steve, explain your situation, post your account info and contact info and he'll get you square.

For what it's worth Extreme 50 and 105 are in the system now for my area, although the area it's not D3 yet. Hoping that's a sign that it's to come soon.

I just re-ran the speed test using »speedtest.comcast.net/
and got a download/upload result of 59 Mbps/10.39Mbps.

The results from the comcast site are consistently better then other test results. Are they biased? can they be believed?

Re: [Speed] Northeast speed changes coming.

It seems like most people here agree that Shaper Probe is more accurate to measure speed than any of the speed test sites

I believe that when a Comcast customer uses the Comcast/Xfinity speedtest site, the servers they can select are all Comcast ones, so the data transfers stay within Comcast's network and don't experience any slowdowns that occur when interconnecting with servers in other ISP networks.

If I select the same Comcast server on the similar »www.speedtest.net site, I get basically the same result, but if I select a server that is located much closer but which belongs to another ISP, the results I get are usually not as good.

This raises an important issue:
What is the purpose of a speedtest?

I use it for consistency. Am I getting a consistent speed over time. Therefore, I have no problem using the Comcast one.

For what am I really getting (no Speedboost Impact). Then I use ShaperProbe.

I've long since given up on speedtests. The only true speed test I use is sustained downloads to see if I get what I pay for. Even Shaper probe has be unreliable for me in a few instances.

They can be useful. I don't use speed tests for anything more than to verify that my connection is working as expected. It's simply a first step that I can take in troubleshooting before applying more exhaustive procedures.

I could see in a few seconds that the recent upgrade was not in effect through a quick speed test. After resetting my modem/router, I could then verify that the speed increase was working, all through a simple online speed test.

Not all areas got the upgrade at the same time. I heard some areas are getting it by the end of next month.

Are you directly connecting (wired) or using a wireless connection? I found that wireless G was maxing out in the high 30's and wireless N is able to get the full bandwidth.

Also some wireless routers have a QOS setting which could be throttling the connection. Either turn off QOS on the wirelss router or if there are settings that would allow you to set the upload and download speed, set them to higher than your connection meaning 50/10 set it to 65/15 to not limit the additional throughput you can get above 50/10.

We got the speed bump in Ross township, just outside of Pittsburgh today. Fastest test I had was 110/22.

Re: [Speed] Northeast speed changes coming.

Your getting some pretty good download results. Your results can be deceiving because from test to test. But If you are consistently getting that speed from test to test, then you can confirm with speedtest.net which has more test sites. Of course I use shaperprobe and a number of other test sites.

Also a lot of different conditions can produce different results even on the same machine not withstanding the conditions outside of the home. Example:
Wireless N



Wireless G

I have an RCA modem and my account doesn't say BLAST, it says nothing. Do I need to contact Comcast?. I got the email. I think I need to have them fix my account and probably need a new modem. I currently get 25mbps and 4 mbps down checking speeds. Thank You.

RCA modem is not a D3 modem approved by comcast, so yes you will need to change it out. I would call them just to make sure you are on Blast.

If you rent your modem just swap it out at the local service center.
