Hi,
I apologize that you have had this experience. This does sound like a localized issue. Have you tried connecting the modem to a different power outlet and plugging it directly into the outlet if you are using a power strip? Sometimes, a fluctuation in power can cause intermittent connection issues or slow speeds.
We will be glad to investigate this further with you, Please contact us privately with your account information. Our email address is cox.help@cox.com. Please be sure to include your name, full street address, and a link to your forum post. As for which device to go with I'm not able to recommend any specific 3rd party modem, but we do have a list of all modems that are verified compatible with our network listed at https://www.cox.com/residential/support/cox-certified-cable-modems.html

Thanks Greg,
The modem is plugged into a UPS (APC Pro 1500S) which is an even better and more reliable solution than a regular power strip . So I can confirm that the issue is not a power fluctuation problem.
Regarding the cable modems, yes, I am aware of the "certified" cable modems, where support immediately refuses any sort of advanced troubleshooting beyond making sure it gets a basic signal. Their first recommendation has been to rent me the Panoramic device (the only supported one, apparently)
The CM2000 I am using is in fact on that list, by the way: https://www.cox.com/residential/support/netgear-cm2000.html
For the record, I have noticed that the Downstream Channel on that modem has been blinking, which means it's not on full service, and the Cox tech that came to my house even showed me that his testing equipment is also showing Unhealthy status
I will send an email to cox.help@cox.com and reference this thread.
Thank you for the response.
You are welcome for the reply from Greg. He's away from his desk at the moment so I am stepping in. We look forward to your email and further assisting you.
Just closing the loop on this communication. I purchased a Motorola B12 and got it replaced, and that resolved the speed issue. I am in contact with Netgear to have them replace my modem, obviously, it has some hardware fault going on.
Thanks for the assist!
