Thanks Darren,

 

I will reach out to my ISP.   I also see that Channel 2 on the Upstream is showing "Not Locked and Power shows 0.0dBmV", is this also an issue?

Also, should the Uncorrectables be zero, as last week they were in the 5 digit number range?

    Hello pquihuis

     

    You will have to ask the ISP about that and the uncorrectables being a low number is fine.

      I have followed up with Time Warner and their L3, but they are continuing to point the issue to my Netgear CM500 modem.  Even after sharing my event log highlighting the errors, they continue to claim that all signal levels are within specification.  To get past the finger pointing, I will rent their modem to assess if my problems continue.  I'll keep you posted.

        I have since then swapped out my CM500 with Time Warner's Arris Cable modem to see if my issues remain.  It has now been 1 month and my daily speed issues have gone away.  I will send my Netgear CM500 Cable Modem back for repair and try again once it returns.
