Re: [Speed] Northeast speed changes coming.

I'm thinking about it but can't trust my area has the new speeds. Seems like some may be right that Comcast has left us Ultra folks in the cold and paying more.

I'm paying a separate $10 a month charge for Ultra right now.

Your Ultra Shaper probe is what mine looked like a couple weeks ago. Comcast did something and now it's dropped but speed tests are still good

Estimating capacity:
Upstream: 2940 Kbps.
Downstream: 33081 Kbps.

Upstream: Burst size: 3654-3698 KB;
Shaping rate: 1754 Kbps.

Downstream: Burst size: 3807-4828 KB;
Shaping rate: 1269 Kbps.

If I decide to downgrade(upgrade) to Blast! I'll re-post. I need to find a neighbor that has Bast to confirm before I change.

Check the forum for someoneelse in the area where you are located. ALso in the Comcast Direct Forum you can confirm with them if its on. Comcast Steve seems quite reliable.

I was able to drop the $10.00 for Ultra, change to a package which included blast with a 2 yr commitment average savings between old package + Ultra and now is $5.00 per month.

Even the Executive Office did not have the correct info about it being turned on here, but as you can see, it is

Thanks,

ComcastSteve started working with me in the direct forums. We tested that the new Blast config is working for my area. Not getting as fast as you but some areas seem better or worse. I only noted that ping times were lower on Ultra. Looking at your tests, that seems to be the case also.

Note these are "best" speed tests.

Re: [Speed] Northeast speed changes coming.

You are getting the new Blast 50/10 in Alexandria City sendjunkmail? I still have not gotten it, and I have rebooted a few times today trying to get the update.

Yes I'm in Alexandria City but....I guess I'm testing it.

dbw09: First what brand/model number of modem/eMTA do you have?

You must have d3 whith 4 channel bonding down or better

Are you using wired connection? Wireless can slow you down for various reasons.

Are you certain you have Blast or Extreme 50 (these are the only 2 to see the speed doubling).

Yes, I have all of the required equipment, I used to be on extreme 50 about a year ago. I have a 6120 that just received the FW push earlier in the week. Unfortunately I am still pulling good old 25/4 (shaped to 15/4). I guess I will have to call in and ask them to roll and re-provision me.

50/10 is the advertised speed for Blast, so you are gettin a bit better than the advertised.

OK I do llive in a rural area and I have worked with Comcast to get good signal levels. So we don't tend to get overloaded.

A couple of my friends in Arlington have already received the the new speeds. So your plan sounds good.

Yeah, somehow when my 6120 received the new FW it set my config file to "default" which basically meant that I never would have received the speed increase, I would have stayed at 25/4 (15/4) forever had I not called. The tech I spoke to said this is happening quite a bit for some reason.

@DBW09. With the 6120 u should be able to see the config. file for your tier. Can you see what it is?

Sorry, I wasn't really clear... I called and the tech fixed the issue. If other people are in areas where the speed increase has gone live but they have not received the increase themselves, it may not be a bad idea to call and have Comcast check to see that the modem is provisioned correctly (since mine was not and apparently it is happening quite a bit from what I gathered). Also, on the SB6120 you cannot see your config file unless you happen to catch it in the logs when it is updated before it scrolls away.

Happy with the results, getting advertised with small margin.

Below & attached are the test results I'm getting on my Comcast Blast service in the Washington, DC area.

Are the results consistent with the newly announced Blast speeds?

Shaper Detection Module.

Connected to server 38.106.70.175.

Estimating capacity:
Upstream: 6769 Kbps.
Downstream: 30733 Kbps.

The measurement will last for about 2.5 minutes. Please wait.

Checking for traffic shapers:

Upstream: No shaper detected.
Median received rate: 6608 Kbps.

Downstream: No shaper detected.
Median received rate: 30128 Kbps.

Re: [Speed] Northeast speed changes coming.

Nope. The advertised (not guaranteed sppeds) for Blast with the new change is 50 kbs down and 10 kbs up)

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.

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
