I subscribed to Bell's 3.0G service for my home office, but I've encountered a serious issue with internet time synchronization that occurs randomly. This problem is particularly noticeable with my IoT devices. When they reboot, they are unable to synchronize with the NTP server. Each time this happens, I have to reboot the Bell modem, and once it's restarted, everything returns to normal.

I’ve tried rebooting the IoT devices individually, but that doesn’t resolve the issue; instead, their time settings revert to factory defaults. In my office, I have an IP camera, a TV/media box, a NAS, and various other IoT devices, wired and wireless as well. They are also appeared the NTP issues.

When the problem arises, I immediately perform NTP testing on my computer, wired connect to Bell modem (please see the attached screenshots).

I called Bell support, she said she is just a Level 1 support and unable to resolve my question, and she will suggested me subscribing a Bell Tech Expert to remote to my computer and they will resolve my issue 🤔. 

What should i do?


Failed: Sync with time.google.com

Every time, after the modem reboot, it will resume everything!!

I just got the problem again, traceroute doesn't work. When the traffic went out from the modem (edge.home), no response from the next hop.

Do you have a VPN in play?

No VPN, direct internet. I also tried to use Ethernet to connect to the modem.

Are you using the 10G network port on the hub?

Yes, i used of the port and connected to the switch, 10G is one of the downstream port to another switch.

But for the testing, i am using my computer and plug to the dedicated port on modem to test it. I also tried to use Wifi to make testing but also failure.
