Bursts of uncorrectables/Lost MDD Timeout/No Ranging Response received - T3 time-out

Moved from an apartment which was new "1 to 4 years" to a home "Duplex" about 15 to 20years old. Had no issue at the apartment using an ARRIS -SB6190. Since moving to duplex home location experienced daily to every other day reboots of modem. Reviewing the status of the modem over time found that it would take bursts of high count uncorrectable errors in the 519Mhz to 597Mhz range. Additionally, some channels would lose connection.

 

With 20 years of carrier experience behind me, figured I would check the house cabling. Over the last few months here is what I have done.

  • Removed all splitters and installed one quad-shielded RG6 15ft long from Comcast entry point "D-mark". So 15ft of new coax from Comcast cable to the modem. This improved signal and situation to a point.
  • Installed new coupler meeting frequency requirements in Comcast box.
  • Installed new connector on Comcast cable in the Comcast box
  • Purchase another modem Netgear CM700

After all of this, I feel confident connection is solid from the Comcast cable through the house.

 

Here is the stats on the CM700 modem currently online about a day in a half. I have not yet had any reboots, but feel they are coming.

Can't see your pics. Since you are a new poster, they likely need to be approved by a Forum Admin. Or you may need to make a minimum number of posts.

You could try hosting them at one of those free third-party pic hosting sites and post the link to them here.

Added link to the first post for viewers who cannot see the image of modem stats

 

Posting an additional image as CM700 has taken another burst of errors, but not yet rebooted.

Another update

I can't tell whether the modem rebooted and the event log stayed intact. Some of the uncorrectable errors reduced, which leads me to believe the modem did reboot. However, I am not sure exactly how the Netgear CM700 is reacting to the issues it is experiencing.

So rebooted the modem to understand how the CM700 event log works. The event log stays intact on the reboots.

Re: Bursts of uncorrectables/Lost MDD Timeout/No Ranging Response received - T3 time-out

The downstream power is on the high side. Is there a drop amp in the coax line leading to the modem ? If so, try removing it and see what happens. The modem may be being over-driven. There were a lot of uncorrectable errors in your earlier pics.

Re: Bursts of uncorrectables/Lost MDD Timeout/No Ranging Response received - T3 time-out

I placed a splitter before the modem a few weeks ago and that made the situation worse. But I can try that again. Modem rebooted again this morning.

 

Here are the stats after it rebooted

EG,

Thanks, I will have to contact Comcast for that to verify. There is no amp that I can see.

After another reboot. Will contact Comcast today to see I can get a tech out here to resolve the issue. Notice downstream channels 31 and 32 not connected.

Re: Bursts of uncorrectables/Lost MDD Timeout/No Ranging Response received - T3 time-out

Luckily, the tech was dispatched out within 2 hours of placing the ticket in with Comcast. That was quick. He replaced the coupler and the cable from the Comcast filter to the house with RG11. Another team will be out to place RG11 and in the ground in 3 to 7 days. He also installed a 6db attenuator to pad the dbmV downstream signal.

He indicated he would contact another technician to come out and test or verify levels at the node to see if things check out there or not.

 

I cleared event log and everything is clean as of right now. Will know in at least 48 hours if the problem changes, persists or clears.

For curiosity, what do the signal stat figures look like now ?

Here they are EG. Note that I have not put a splitter on to the xfinity cable box yet, which would take these levels down 3.5dBmV. Rather wait and see if the latest changes make a difference.

Re: Bursts of uncorrectables/Lost MDD Timeout/No Ranging Response received - T3 time-out

Well, I figured replacing a cable wasn't going to correct it, and I mentioned that to the tech. Normally a cable or connection issue would be more consistent, ruling out something cause interference or perhaps rain/water. However, he did take some possibilities off the table. No reboot yet, but only a matter of time. Will continue to monitor.

 

Interesting, the changes in dBmV between the last stats above and the stats below in a 6 hours time span. Some channels are +1 and some up to +4dBmV. Would that be normal? Would day heat to night cooling cause such an effect? Regardless, none of the levels are outside the modems operational range.

 

Here are the latest stats after refreshing

Re: Bursts of uncorrectables/Lost MDD Timeout/No Ranging Response received - T3 time-out

Yesterday I installed a splitter to connect to the xfinity cable TV box. Then reset the modem this morning at 7:15 or so. Cleared the log. Below are my stats and logs after six hours of the manual reboot. 

I have not to my knowledge experienced a reboot that I am aware of. However since experiencing the issue for Sep 15th, I don't want to yet call it good to go.
