C6300 reboots at random times

[olerma01]

I have been using the C6300 cable modem/router for about 5 months now.  This week I have found that it is rebooting itself at random times, usually once per day.   My service provider is Spectrum.  What can I check to find the cause and remedy this problem? 

Thanks,

Hello olerman01

You can log into the modem and find the logs under Advanced-Administration-logs and post them here.

Currently the log only contains the last 6 hours of activity and thus far I have had no reboots today.  The last known unexpected reboot occured on 6/6/17 at around noon local time.   Once it occurs again I'll export the log file.

Thank You

This just started happening again.  Reboot occured at around 12:15pm Central time.   I'm attaching the log files as screen shots.  I haven't been able to export them as email yet. 

The thing that sticks out to me is that at 12:12 there appears to a remote login from 178.234.188.240:56718 to my local

192.168.0.38:8000.  That .38 isn't a PC but a network hardware device. 

I traced that remote IP and it's Russian.  WTF?  Are Russian hacking/attacking my home network?

Is this a device that has anytype of apps?

The device at 192.168.0.38  is my home security DVR.  It records and plays back footage from my security cameras.

Thanks.,

Did you remote into your cameras and was on a proxxy server somehow from your phone or something.

I can remote into the DVR and view the camera video feed, but not the cameras themselves.  They are analog, not IP.    I do have port forwarding setup on the router to enable this remote viewing.

Thanks...
