Inconsistent connectivity since about May 26th

Hey all,

I've been experiencing intermittent connectivity for the past two and a half weeks that I assumed was a temporary issue, but it seems that this is not the case. Things look OK to a bit slow one minute when just browing, then all of a sudden there is packet loss, latency spikes, and it's like I'm back to pre-DSL days. Streaming video working one minute, broken the next. Testing against the myspeed.visualware.com Dulles Virginia server has shown consistency issues:

Powercycling was the first thought, but with no change in symptoms.

On the DSLReports Comcast HSI forum ( http://www.dslreports.com/forum/r27152924-Connectivity-Bug-in-May-2012-SMC-D3G-Software-Update- ) there was some discussion of a modem rollback, and my SMC does have the 1.4.0.49.7-CCR firmware. If it is indeed a rollback then it hasn't helped.

Any ideas? Attached is some info from my SMC.

Thanks,

-Alexander

Alexander,

Glad to be of assist and good to hear!

Regarding that "missing" upstream channel, you do not have to worry. The number of channels are based upon the market you are in; hence you are in a market that uses three upstream channels.

Please continue to post technical support questions and concerns you have in this forum.

Thank You

Thanks for seeting up a Tech call Jon. The tech arrived 3 hours EARLY (kudos to him), looked things over, reseated the cabling removed a splitter that was no longer needed, and things seem to be back to normal. He may or may not have nade some adjustments elsewhere in the building as well. Here's what things look like after his visit:

All in all things appear to have improved enormously. My only remainin question is should I be worried about the one Upstream Channel that is showing as Not Locked?

Thanks,

-Alexander
