ONU rebooting on its own daily

I have this problem for nearly three months now. The Nokia ONU G-140W-C reboot once / twice daily. When I am connected to my office VPN and in a conference it takes a lot of time - about 4-5 minutes to get back into the meeting. It is really become non usable for office meetings.

It started happening 3 months ago when there was some fault in Airtel equipment in our apartment and the ONU was constantly rebooting. Then they changed that faulty equipment connecting several floors. Although the immediate constant reboots stopped, but the ONU keeps rebooting daily once, twice or even thrice.

If I telnet and see the reboot reason - it is not changed. The logs at debug level do not show any reboot reason or anything unnatural. Simply that the booting process starts suddenly. It seems like firmware crash, but not even kernel panic is logged.

I asked for replacement modem from Airtel and they provide Nokia G-140W-F. But it is showing the same issue - it reboots daily once / twice. Today it rebooted 3 times within 6 hours.

Some people in our apartment complex are saying they also face ONU reboot issue daily. But it is only apparent if you are in video conference, otherwise with buffered video you may not notice.

Anybody faced this issue, any solution?

I think they have installed an olt inside your apartment complex which is faulty.
They have to fix the olt inorder to fix this issue.

What is the difference between Nokia G-140W-C and Nokia G-140W-F?
Any difference in range or stability?

It took 3 complains and a number of emails before they even considered replacing the modem. I don't think they even know the full form of OLT. I raised a complaint now, they auto resolved it within 3 hours. I feel they don't want to debug the issue. It seems I'll have to downgrade my plan and with the money saved get another broadband plan from Tata Sky or Jio as a fallback.

No change in functionality that I can see.
