corrected and uncorrected errors on MB8600 jumped
I've been monitoring my corrected and uncorrected errors with a script on my MB8600 for the past few months. Things have been pretty normal with the uncorrected total under 1000 errors. The last day or so the number of corrected and uncorrected errors have skyrocketed and I have not done any coax changes within the house. Can someone take a look at my screen shot and give me some ideas? Is it possibly due to the recent heat wave we are seeing here in the Denver area? I'm open to suggestions. thanks

The downstream power is marginal / low / weak and it may be intermittently fluctuating even lower to out-of-spec levels. Also, the SNR is low / out of spec on a few of the channels. And the upstream power on channels 4 and 5 is on the high end. That can cause random disconnects, spontaneous re-booting of the modem, speed, packet loss, latency problems, and the un-bonding of channels.
In an 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 5-1000 MHz, bi-directional, and no gold colored garbage from Home Depot, Target, Wal-Mart, etc. Splitters should be swapped with known to be good / new ones to test.
Also check the coax cable for any damage such as cuts, nicks, abrasions, kinks, sharp bends, etc.
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.
Good luck with it !

Thanks EG - I haven't made any changes to the internal coax network in months. I do use these splitters and terminate any open connections. Also use the POE filter as has been mentioned in the past

I did see an Xfinity truck in the neighborhood so maybe there is some work being done on the cable plant. I will monitor for a few days as this just spiked to the moon this morning. Prior to that everything has been fine.
If nothing gets better I will schedule a tech to check the line coming into the house.
appreciate the response - thank you!

If there is nothing more that can be done to improve the connection quality, then yes, you'll need that tech visit.
Bear in mind that if the premises facing techs can not find or fix a problem at your home, it is they who are responsible for escalating it to their line / network / maintenance dept. techs. The problem may lie beyond your home in the local neighborhood infrastructure somewhere but it is their S.O.P. to start at the home. And if the problem is found to be on their side of the demarcation point, there will not be any charge.
Good luck !
