Detected increasing uncorrectable error count

I just added a CM600 (Firmware Version V1.01.12, Cox Premier 150/10) to replace a Cisco DPQ3212 Telephony cable modem. As part of the old modem installation, there was a splitter with a terminating resistor between the wall and modem. Removing it would cause endless reboots of the Cisco.

 

Since installing the Netgear, I have tested both with and without the splitter/terminating resistor combo and seem to have essentially the same quality of connection either way with no mystery reboots. There is something that concerns me that I hope the collected wisdom can guide me on.

 

My power on each channel increased markedly on each channel without the combo, but the Correctable/Uncorrectable count also jumped (at least on channels 1-12). SNR remained the same either way. Should I keep the splitter/resistor or not?

Hello jkernitzki

 

I would have your ISP come back out and check the lines seems to be a issue.

Re: Detected increasing uncorrectable error count

splitter is OK but 3 channels on the COX network have issues. Please ask cox to fix the node for those 3 channels. Most likely, your whole street/neighbors should have this problem as well.

This is the latest after a reboot (~5 days uptime currently): Screen Shot 2017-08-04 at 10.38.55 AM.jpg

channels 7 and 8 are bad. Transfer lot of data for a day and see how the counts look like. 

 

right now, the counts are low.
