Hi, LDTurpy.
I'm sorry to hear you're seeing increases in your data usage. I can understand how it would be concerning. We're working to better enhance how data is categorized within the data usage tool. You may see the data categorizations on insights page shift over time. I can't say I've heard other customers reporting a large amount of activity in the Network Management & Testing category. It's possible an unrecognized traffic or activity has been miscategorized. If so, you'll probably see the data shift over the coming months. Hopefully other community members will chime in to share what they might see when checking their own activity.
If you are using a Cox Panoramic WiFi modem, you may want to try using the WiFi app to determine which device or devices are using the most data to try to narrow down the activity that way. You can learn more about the Panoramic WiFi app at https://www.cox.com/residential/support/cox-panoramic-wifi-app-features.html.
If you need additional support for your data usage, please email us at cox.help@cox.com with your full name, complete street address, the details of your inquiry and a link to this forum thread.
