Thank you Cox for fixing the extreme noise issue in my area, plus other damaged hardline connections leading to my condo complex from the main street. I saw a bucket truck near a hardline drop down the street from me and bang, my signal issue was fixed. I don't think node overcrowding was my issue. It was a whole lot of damaged connections outdoors and in, which were causing microreflection noise in the whole network. MER (went down to 32) was suffering when the noise would show itself. I don't think it was node ovecrowding in my case.
I know this won't help you, but at least you have some comfort in knowing it's not just you. It's likely everyone who has Cox internet.
I've been suffering from the same absolutely horrible internet connectivity issues as well for nearly the past 2 weeks. Every single night straight for the past week it's been like that here in Cleveland Ohio area.
I normally don't run speed tests unless I see extreme buffering on streaming or inability to use the service to connect up to work. When I can feel and experience the issues is when I run the speedtests to check if it's really an issue. I'm on Gigablast tier. The cable modem signal levels have been fine in my situation.
I normally get sustained 940 mbit/s download and 35 mbit/s upload, but tonight has been as pathetic as yours. A rather anemic 61 download and 0.31 upload.
I'll throw my hat into this issue as well. For the last 2-3 weeks my connectivity randomly drops, and during those times I get absolutely horrible connectivity, but the modem and the website are all reporting no issues. So when I called (3 times already) I was pretty much given the run around, from everything that it was in internal home issue, to no issue is seen. SO YEAH! Hearing others are having this issue at least resolves that concern.
Now I'd love for COX to come out to Henderson, NV and fix the issue on this end as well!
