Daily timeouts modem logs provided

Hi,

I am getting daily timeouts of the internet connection. And modem reboots at that point

Looking at SB8200 logs

[Image Removed: "Personal Information - MAC Address"]

Stats look ok:

[Image Removed: "Personal Information - MAC Address"]

Is this line or modem?

O/k it appears that your images of the signal status and the error log entries have been removed due to them containing your modem's CM MAC address and the CMTS MAC address which are considered to be personal information. The posting of personally identifiable information is a violation of their forum guidelines. The forum bot will not allow them to be seen publically.

What you can do instead is copy and paste all of the text (instead of using an image) but you'll need to redact all of the CM MAC and CMTS MAC addresses, then paste them into your next post here.
