Re: [Speed] Comcast Business Class Speed Upgraded in California

said by jlivingood:

Okay, sorry to sound like a broken record but try again and also post the name of your bootfile if you can.

Modem rebooted here and getting the same results.

DiffProbe release. January 2012. Build 1008.
Shaper Detection Module.

Connected to server 213.244.128.168.

Estimating capacity:
Upstream: 7873 Kbps.
Downstream: 35179 Kbps.

The measurement will take upto 2.5 minutes. Please wait.

Checking for traffic shapers:

Upstream: No shaper detected.
Median received rate: 7728 Kbps.

Downstream: Burst size: 19489-19804 KB;
Shaping rate: 28746 Kbps.

For more information, visit: »www.cc.gatech.edu/~parth ··· iffprobe

If I understand the info presented correctly, my upstream is hard locked at 7Mbps with no chance of powerboost and the downstream has capacity for up to 158Mbps but I am being shaped to 28Mbps.

On speedtest.comcast.net I still get 30Mbps down and 7Mbps up. So a slight PowerBoost on the down and nothing on the up.

Maybe I used all my number of allowed PowerBoost usages this month. /sarcasm

Cannot see boot file as customers are not allowed into that section of the SMC router.

I think your downstream PB max is:

Downstream: 35179 Kbps.

For ~20MB of data (19489-19804 KB)

This matches your Speedtest numbers pretty well.

Yep, very similar to what I'm seeing on real downloads, too. About 34-35 Mbps during power boost.

Nope, you're getting powerboost to 35mbps and shaped to 28mbps. The burst size detection in Shaperprobe will be thrown off if you still have the misconfigured shaping policy on your device.

I've seen others post 60+mbps speedtest results with Powerboost -- we never got those speeds here in the Minneapolis market. What you're seeing right now is pretty typical to what we've always seen in this market, which is Powerboost limited to the upper thresholds that the marketing materials usually list.

Thanks for the explanation. When I was in WV and then when I moved here to VA, I was always getting 70+/10 on the powerboost. THat did not change until after this upgrade was completed.
