I have a 2-year-old Arris T25 modem.  Every two days between 9:30 am and 10:45 am, it reboots without any action by me. It’s been happening for weeks, and always two days between reboots, no more, no less. Is it the modem, or Xfinity?

The event log always reads the same:

PacketCable Events

DOCSIS Events

Four minutes before the reboot

Just before the reboot

When I check the status, all parameters are within the proper range, but I don’t have a reading from the moment the modem reboots.

 

I'm trying to decide whether to replace the modem with the Netgear CM2050V-100NAS, or call Xfinity.

 

Thanks.

T3 issues tend to indicate a line issue. When you get those, it can trigger a reboot on the modem. Surprising it happens at the same exact time. 

Could you please let us know if there have been any recent changes to your network, such as an upgrade to your internet speed plan?

Additionally, would you help us with the internet speed plan you're currently subscribed to?

When rebooting the cable modem, does it completely power off, or does it remain on during the process?

 

Thanks for the response.  Just to close the loop, the issue is resolved.  Here’s what happened.

I went to the Xfinity site and followed instructions which involved opening the app and doing a reset of the modem from there. I don’t know if that’s just a reboot, or something else.  I followed that with a chat with Xfinity where they pushed some buttons on its end and reported back that the modem and the line were both fine.  Somehow something that was done fixed the problem without having a technician visit.  The modem has not rebooted since Feb. 16, so I’m keeping the T25.
