Why so many "No Ranging Response received - T3 time-out" daily events in my modem log?

Getting Internet disconnections several times throughout the day, and it so happens that they coincide with "No Ranging Response received - T3 time-out" events in my modem's log. Modem is an Arris Surfboard S34. How can this be fixed?

When did this issue begin? Do you notice anything else in the event log? Remember to remove or censor your Mac address if you post it here.

@Aqua1ung Thanks for adding a post to the community. This can be fixed by troubleshooting the connection when you see an interruption of service. Use the steps here https://www.xfinity.com/support/articles/internet-connectivity-troubleshooting, and it will work on the connection. If it's not fixed, it will allow you to schedule a technician to continue troubleshooting onsite.
