Surfboard SBG7600AC2 rebooting on its own and intermittent connection

I have had an Arris Surfboard sbg7600ac2 for about the last 3 years, everything has been working fine until this morning.

My connection kept dropping out on my connected devices and when I would go check the router, all the lights were off except power.

It would restart and bring all lights back on, and all devices would connect then after a couple minutes it would turn off again and the modem would drop back to just the power light, then restart again. Over and over.

I've unplugged the modem for several minutes then turned back on, same problem. I've reset the modem to factory settings, it works for a little longer then same problem. 

Running firmware 9.2.103AA85

 

Any help would be appreciated.

Got a copy of the modem’s event logs? It could be the cmts resetting it due to line issues

If you are having issues with the event logs, I suggest to contact internet service provider for further assistance.

But from event logs can you make out what it wrong.

I am able to get even logs so that does not seem to the problem.

Thanks

Event logs completely depend on the signals provided by the internet service provider. So, they can only check the event log.

Could you let us know the exact issue you are experiencing with this modem?

is their a log to see what is causing the device to reboot. Trying to sort out if it is modem issue  or is it Comcast ISP sending some updates that is causing the reboot.

I suggest checking whether the modem is rebooting without a co-axial cable.

There is no option to check the time if the modem reboots in the night.

I am having the same issue with what appears to be the same model unit. I have not been able to get any help from the Arris reps that I have spoken to.  In the past hour the modem has rebooted about 8 times. This has been happening all day. I need some real help getting this resolved. The last rep asked me to call back when my internet was back up. How much sense does that make if it’s a constant intermittent problem. It went down 2x’s when speaking with them.

If the modem is rebooting on its own, I suggest checking without a co-axial cable.

If you are experiencing intermittent internet connection, kindly let us know whether it's through a wired or wireless connection.

If the issue is with both wired and wireless connections, I suggest checking the cable signals by following the steps on the below given link:
