CM 1000 - Error Log Help

CM1000 Error LogCM1000 Error Log

CM1000 errors being thrown several times throughout the day.  From previous posts read of removing any cord splitters.  Did just that and errors still being thrown.  Any help would be appreciated!

Can't see your pic. Since you are a new poster, it needs to be approved by a Forum Admin. That could take some time. In the interim, you could try hosting it at one of those free third-party pic hosting sites like Imgur or Photobucket and post the link to it here.

Or copy all of the text of the status page and paste it into the body of your next post h

We need to see the signal status numbers as well. Please also post the *Downstream Power Level*, the *Upstream Power Level*, and the *SNR* (Signal to Noise Ratio) numbers as well.

Re: CM 1000 - Error Log Help

The upstream power is on the high side 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: CM 1000 - Error Log Help

Thank you for the information!  I read this on the previous thread and removed the splitter.  It is now direct from the wall outlet to the modem.  Will try for a tech to come out. 

 

As an aside, have yet to get the 1GB speed, with 944 mbps the fastest at 7AM.  Typical peak speed is around 860 mbps with the lowest 740 mbps.  Any thoughts on whether that's normal?

FYI. Around 940 is about the highest speed to be expected due to the inherent overhead involved. It may be fluctuating lower due to local network / system capacity / traffic congestion issues.
