Download speeds constantly drop to 30 mbps on a 500 mbps plan.

I am getting constant notice 16 and 24 errors on the cable modem. 3 channels get high corrected and uncorrected errors. I am unable to go a full 2 hours before it drops to 30 mbps.

    It started up again so I had a tech come out it was a filter in the line so all this time it was a filter the tech pulled out :(.

Same issue. Started many weeks ago. Replaced modem due to age and "regular maintenance" thinking the upgrade would help. No change. Resetting modem through smarthelp will solve the issue for about 5 minutes, then back to 30. Almost like its being throttled. Upload is not affected. I have had dips to 2mbps, but typically stays at 30.

Please post an update should you resolve your issue.

Hi Gecko87,

 

 

I'd be glad to review the modem logs and investigate further. Please send an email with your name, address, and reference to this post to cox.help@cox.com.

 

 

Thank you.
