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.

@XfinityBenny​, thanks, I had a technician come, and he did fiddle with some of the modem cable and whatnot, yet I am still getting these errors in the modem log. Technician said that there is nothing wrong with my side of the equation (namely the cabling and the modem), so that means that the issues are elsewhere deeper in the network. This cannot be fixed by sending more technicians to my home. This requires a more radical approach, which, I guess, Xfinity may not be willing to undertake ...

I’m glad to hear a technician went out and checked the connections @Aqua1ung! Outside the errors in the modem’s log, are you noticing any connection issues on any of your devices?

@XfinityAldrik​, I have been getting Internet drops, though I can't say if these errors in the modem log have anything to do with that. At some point I was tempted to assume that that was the case.

@Aqua1ung What troubleshooting steps have you tried so far like resetting the modem or checking the cables to ensure they are finger tight?
