Connectivity Issues

Like others in this forum, we have been experiencing connection problems.  Intermittent internet, intermittent streaming.  These issues improve immediately after a reboot of the gateway, then return to the state of a poor signal.  Our pc's are in the office, the same room as the location of the gateway, our tv is on the other side of the wall of that office. We own a MT7711 Motorola gateway.  I have been told that my modem is fine, it is the connection to Comcast servers.  We are supposed to have Gig service, but find the best download speed that we can get is half a gig. In querying the gateway, I have found that the event log has reported excessive number of Unicast Maintnenace Ranging errors, without responses.  I have been told that these time outs point to an issue with our line.  

Before I call the technician again, I would like to receive some sort of assurance that our signal will be examined from the the outside into the house, and that we don't need a new modem. 

I have attached the  log info here:

Re: Connectivity Issues

The upstream power is too high and it may be intermittently fluctuating even higher to out of spec levels. That can cause random disconnects, spontaneous re-booting of the modem, speed, packet loss, and latency problems.

In a self troubleshooting effort to try to obtain better connectivity / more wiggle room, check to see if there are there any excess/unneeded coax cable splitters in the line leading to the modem that can be eliminated/re-configured. Any splitters that remain should be high quality and cable rated for 5-1002 MHz, bi-directional, and no gold colored garbage types like GE, RadioShack, RCA, Philips, Leviton, Magnavox, and Rocketfish from big box stores like Home Depot, Lowes, Target, Wal-Mart etc. Splitters should be swapped with known to be good / new ones to test

If there aren't any unneeded splitters that can be eliminated and if your coax wiring setup can't be reconfigured so that there is a single two way splitter connected directly off of the drop from the street/pole with one port feeding the modem and the other port feeding the rest of the house/equipment with additional splits as needed, and you've checked all the wiring and fittings for integrity and tightness and refresh them by taking them apart then check for and clean off any corrosion / oxidation on the center wire and put them back together again, then perhaps it's best to book a tech visit to investigate and correct.

Re: Connectivity Issues

First off, thank you for the fast response!  We are going to take a look at the items that you have suggested.  We have one splitter, but it may not be of high quality.  

I also wonder if our neighborhood isn't part of the issue?  There are many multi-unit housing structures.  More than any other neighborhood that we have previously lived, where there was never a connectivity issue.  Even when we owned our modem, and had a separate router..

Re: Connectivity Issues

We have checked the splitter, as recommended.  We use two of the four connections, and it is made by Extreme Broadband, one installed by Comcast two years ago.  We now are wondering if an amplifier is needed?  If so, what would be recommended.  It is still our opinion that this is an issue with the old cable to the house, which is literally very old.  The former owners of the home had not used cable.

Re: Connectivity Issues

It may be best to get a tech out to investigate and to determine what is needed. Good luck !

Re: Connectivity Issues

The Comcast technician examined our line outside the home, and found that it was "padded", and removed that.  He also realized that our main tv had too many breaks in the cable (four cables were patched together)!  Rectifying these issues have given us a quality signal.

Re: Connectivity Issues

Good to hear ! For curiosity, would you please post what the signal stats look like now ?

Re: Connectivity Issues

Download speed increased by about 150% on both pc's!  Upload speed decreased.  TV streaming faster, and now reliable.   No more rebooting the modem.  On the phone call to Comcast, the tech said "You need a new modem".  When I told him that I had bought it in December of last year, he said that "it was the model that did not support the latest docsis rating"   I told him that was incorrect., and that it was the recommended model from Comcast.  Then he hung up!  Fortunately I received an immediate call back from a knowledgeable tech that scheduled the service call.  The tech that came for the repair was great to deal with.   

 

I want to emphasize what a pleasure it was to speak to this Community!  I will come here FIRST whenever an issue occurs.  It is extremely helpful to get the "triage" step before calling!

Re: Connectivity Issues

O/k well for curiosity, I wanted to see the current signal stats so that we could compare them to the prior stats in order to tell how much of an improvement was made, or whether they were borderline / marginal. No worries. Happy surfing !

Re: Connectivity Issues

Well, things have only improved slightly.... Not much wiggle room, especially as the higher temperatures of Spring and Summer are approaching (higher temperatures make the signals even weaker). Hope that things hold up for you. If your problem returns, get the techs involved again until it is fixed properly. Good luck !

Re: Connectivity Issues

Hmm.  So you believe that there is something that the tech missed?  He said that the line coming to the house was new (five years old).  Does that matter?

Re: Connectivity Issues

The numbers don't lie. But it may not be his fault. The problem may lie farther away in the neighborhood lines somewhere beyond his jurisdiction. But it is he that is responsible for referring it to their line maintenance department techs if it's something that he can't find or fix.

Re: Connectivity Issues

Thank you again, for your insights.  We are going to take a "wait and see attitude"  at this point.  But I appreciate learning more about this, as we always feel as though  we are at their mercy.

Re: Connectivity Issues

After the technician's visit, things were fine for a week.  Then earlier this week, we are back to the same issues.  Although our pc internet speeds are slightly better, we are unable to stream anything on either TV.  

Here are my stats from the gateway, yet again...  I am placing a call today.  Now we are really P'Od

Re: Connectivity Issues

The upstream power still needs work. There's no wiggle room...

Re: Connectivity Issues

We just returned from the Xfinity store, to get another gateway.  After installation, things appear normal again.  We shall see....I give it a week.  Thank you for your support.

Re: Connectivity Issues

O/k well changing the device can't change the line conditions / connection quality. Hope things hold up for you. Good luck !

Re: Connectivity Issues

Hi Remember me?  One of many, I suppose, with puzzling connectivity issues with my own gateway??  The gateway was defective all along!  I found that out when someone else attempted to put it on their Comcast network.

 

I now have the refurbished Motorola MT7711 gatway back, and up and running.  However, with my newest device, an HP laptop,  I barely can get speeds of 100 mb with my GB service contract.  So, I am back looking at the rating of the cable into the house.  Do you know what the cable from the pole should be?  Ours is from 2012.  The identifying info on the cable is "FPC Perfect Flex 6, Series 18, CATV 2, 3. 

 

We were told that this is the latest grade.  But is it???
