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.
ditto for me. Exactly how you explained it as well! Usually if we reset the whole kit and caboodle (modems and wifi), in the past would help (most times for a couple of hours), before need to repeat. Since Friday, rebooting everything has not helped. This morning, it went from 5 mps to 50... Usually see in the 200 range. Like you said, upload speeds have not been affected. Since COX feels the need to tell all of us to email cox.help@cox.com, will be sending my info as well.
