CM1000 How to stop daily reboot

Hello I need help troubleshooting why my modem restarts itself every day at a specific time. I'm not sure if it's because of a DHCP lease time or something else. Here are some log messages on my modem.

I've already tried factory resetting the modem and the problem still occurs.

Thanks.

Re: CM1000 How to stop daily reboot

Same issue just started. I have the same firmware. What gives? Anyone got ideas?

Re: CM1000 How to stop daily reboot

Have the ISP check the signal and line quality UP to the modem. 
Be sure there are no coax cable line splitters in the between the modem and ISP service box. 
Be sure your using good quality RG6 coax cable up to the modem.

Re: CM1000 How to stop daily reboot

extremely high Upstream power. It is blasting at 53dBmV right now which is very high.

 

do you have any splitters?

 

If not, you should request ISP to reduce the US attenuation.
