2 edits | [Speed] Slow Upstream Hello,
Will you please review and consider the following?
Two (2) DiffProbe (ShaperProbe) test results are provided, both of which indicate significantly less Upstream capacity than is to be provided with XFINITY Performance. In this area, XFINITY Performance is to be "Downloads up to 20 Mbps, uploads up to 4 Mbps with PowerBoost".
In the test connected to server 203.5.76.164, the Upstream capacity was 933 Kbps.
In the test connected to server 4.71.254.149, the Upstream capacity was 970 Kbps.
*** First Test Results
DiffProbe release. January 2012. Build 1008.
Shaper Detection Module.
Connected to server 203.5.76.164.
Estimating capacity:
Upstream: 934 Kbps.
Downstream: 24823 Kbps.
The measurement will take upto 3.0 minutes. Please wait.
Checking for traffic shapers:
Upstream: No shaper detected.
Median received rate: 933 Kbps.
Downstream: Burst size: 9435-9897 KB;
Shaping rate: 15978 Kbps.

The DiffProbe (ShaperProbe) tests were conducted on a single Windows XP PC connected via CAT5 cabling to a Zoom Telephonics 5341 cable modem (a wired router which is typically used was removed for the tests).
I have attempted self help such as rebooting the cable modem and PC, checking for loose connections, inspecting coax and CAT5 cable runs, etc. None of these efforts have improved the Upstream speed. |

kudos:9 | What do your modem's signal stats look like ? Get them here; »192.168.100.1
Please post the *Downstream Power Level*, the *Upstream Power Level*, and the *SNR* (Signal to Noise Ratio) figures. |

Huntsville, AL | your US power level looks low to me - most modems I've seen seem to work best with an US level in the low-mid 40's. The DS looks ok, and there's not really enough room for you to just pad the modem by 10dB. It looks like you're going to need to get a cable tech out there to have a look. |
