can someone give me an opinion on these modem stats I think I am going nuts

Hello majorkong,

Based on this report, it appears your downstream signal to noise is not within the recommended perimeter.

Normally it should be around: -22dB to -29dB range.

In most cases a tech call is warranted here to fix the issue.

Majorkong could clarify a few items for the community?

1. Are you still having this issue?

2. Before any work on the pole did your service had a similar issue?

Thank you

Hey Jon

thank you for taking an interest in this. Here are the answers to your questions

1 yes we are STILL having exactly the same issue.

2 yes we have had issues that CAUSED the work to be done on the pole.

so far we have had:

1 four onsite tech visits ( one replaced all the cable FROM the modem to the outside box and checked the box) ALL techs have escalated the issue to the line manager level.

2 on comcasts suggestion, we argued it was pointless, the line speed was increased to 50mb from 16mb AND a protention trace put on to check. This did NOTHING except increase the error rate.

3 we have started to canvass other businesses in the area ALL have the same issue and ALL have reported it to no avail.

4 the "protention" department are worse than useless as they seem unable to see what the techs AND our datamonitors see and keep asking "if you are having problems call the help line..." Completely useless in our opinion. They are undoing all the EXCELLENT work the frontline help desk are doing. What is the point in excellent frontline people if the back office people are incompetent?

We have stated, on the record, several times that this is a backplane infrastructure issue and NOT localized.

Thank you for clarify majorkong, I appreciate it.

I've checked the region where you are located and found the following:

1. There is some signal noise in the line but they are corrected on the node.

2. On the node it-self there is not enough devices to warrant a node split.

majorkong, can you setup the following test and post it for the community?

On your down time or in the weekend connect a single computer directly to the modem.

Start an extend ping test over that period time using a program such as: pingplotter

Once the test is completed, please post it here so the community further analyze and assist.

Thank you

Hey Comcast John

thank you so much for the reply and the checking of our region. Here is the progress so far:

1 I will be meeting with two representives of Comcast tomorrow to address my concerns. Uppermost in my mind is the possible data red lining of my fellow immigrant businesses. A possibility being raised with Sen: Durbin, Kirk,Sessions,Graham,Comyn hopefully in time for their discussions on 4/21/15 re Comcast/Time Warner.

2 I do not think pingplot test will help as we are already addressing this issue in a more widespread manner using other techniques. The problem is now known to be more geographically distributed than just my location and we will gather the necessary data to prove our point using experts from the fine universities that surround us. I think this will carry more weight than my pingplot and will not take any more of this forums time.

I think all parties know the root cause of this issue and know the solution. The issue is how quickly will they address it and if it will be necessary to make this political especially in the run up to an election coming from a demographic that is sought after by ALL candidates.
