SB6190 with Uncorrectables

Is this number of Uncorrectables okay?  I am on an SB6190.  I never had this many until about a week ago when i was having issues and reset my modem.  I also noticed COX updated from 24 active down channels to 32 at that same time. At this capture, Modem up time was 5 days 16 hours. I have DirecTv for TV and COX for internet only.  Cable modem is on its own dedicated line from DMARC to wire closet.  No splitters anywhere. New Cable run from COX technician about 3 years ago.

    I wouldn't say that is normal. I can't think of any troubleshooting to try though. I would suggest a technician come out to have a look, see if something happened when upgrading the CMTS. Issue is probably outside, but you need a standard technician to get the paper work going for maintenance.

    Hi Mike,

    We can investigate the issues with what you're seeing in the modem log. We can take a closer look at what's going on, can you send an email with the name and address listed on the account to cox.help@cox.com? Thanks.

    Are you in AZ? If so, I think you hit the nail on the head. See this post:

    "There has been an issue with errors coming through the roll off at those very high set of frequencies off plant, mostly nodes in older areas. You need to have another tech out to verify errors off plant on those frequencies and refer to the appropriate department."

    "definitely issues coming from the headend in South Scottsdale"
