Modem Errors - Excess Power & Dynamic Range Window Violation

Over the past week I was having a problem with modem dropping to 90mbps DL. After a reboot it would connect at 900mbps but then 15-20mins later it was back down to 90mbps. While diagnosing this issue...

      Hello Kengasper,

      I am sorry to hear that you have been experiencing speed troubles. Power events and errors on the modem can be a symptom of an issue. I would like a chance to run some tests to see what's going on. When you have a chance, can you email my team at cox.help@cox.com with your name, address, and a link to this thread? When was the last time that you had a technician out?
