*SOLVED* Side-grade from Ultra to Blast - traffic shaped


Large file xfer shaped to 20 MBs
Ok, so I decided to side-grade from Ultra 22/5 to Blast 50/10 as many people in the San Francisco Bay Area reported the faster speeds. That was last Thursday.

I rebooted the modem several times but I still had the Ultra provisioned speeds so I posted to the Comcast Direct forum. No answer after a few days (I sure do miss ComcastSteve) so I connected with support again tonight using the on-line chat. They found, as I suspected, that my modem had not been re-provisioned so they pushed the Blast config to it.

Below are my shaperprobe results:

DiffProbe release. January 2012.
Shaper Detection Module.
 
Connected to server 4.71.251.175.
 
Estimating capacity:
Upstream: 20028 Kbps.
Downstream: 117525 Kbps.
 
The measurement will last for about 2.5 minutes. Please wait.

Upstream: Burst size: 6225-6803 KB; Shaping rate: 4237 Kbps.
 
Downstream: Burst size: 12193-13319 KB; Shaping rate: 19245 Kbps.
 

DiffProbe release. January 2012.
Shaper Detection Module.
 
Connected to server 217.163.1.74.
 
Estimating capacity:
Upstream: 19936 Kbps.
Downstream: 121085 Kbps.
 
The measurement will last for about 2.5 minutes. Please wait.
 
Checking for traffic shapers:
 
Upstream: Burst size: 6195-6751 KB; Shaping rate: 4218 Kbps.
 
Downstream: Burst size: 2280-2776 KB; Shaping rate: 19784 Kbps.
 

Notice that in both cases, my modem seems to be shaped to 20/4 (Performance tier?). To confirm, I tried downloading a large file (Mountain Lion from Apple) because they use a high-performance CDN that always pegged my 22/5 at 24 previously.

As you can see from my pfSense traffic graph, the traffic seems to be shaped around 20Mbs.

1) Are other Blast subscribers in the Bay Area seeing a 20/4 shaped speed on an Arris TM702G after the CA speed upgrade rollout on the 19th?
2) I have tried 3 times with Comcast so can I get this resolved?

Thanks in advance,
Bruce

Amazing! Netcool PM'd me last night to say that the cs rep had in fact pushed the wrong file to my modem so he fixed it while I was asleep ;)
