What is the minimum signal strength or standard that Cox should be providing?
Hello, your modems signal levels appear to be within the normal parameters and this includes your Tx and Rx levels. I'm not detecting any ingress (noise) on the modem or any packet loss. Are you hard-wired when experiencing drops in service or are you on WiFi? -Kevin M. Cox Support Forum Moderator
Everything I can find indicates that an upstream signal level should be between 40-52 dBmV for DOCSIS 3.0, and 45-51 dBmV for DOCSIS 3.1. I was unable to post a picture of my upstream signal levels, but they were 39.2 dBmV. What can be done to achieve acceptable signal levels? Additionally, the modem was only able to bond to 4 upstream channels, not the full eight the modem supports.
This morning, signal levels are down to 37.7 dBmV.
- Any modem will only bond up to 4 upstream channels for now until our cable plant supports more. It sounds like we may need to have a technician back out to investigate the signal since it has been fluctuating. You can email our team at cox.help@cox.com if you would like to setup an appointment.
