I have a surfboard S33 that I’ve been using for about a year now. I guess I’ve been tardy in reporting this issue.  The modem keeps rebooting multiple times during the day and the restart usually takes about 5-7 minutes. I’ve spoken with Comcast about this and they indicated that everything looks good from their end. They aren’t not seeing any errors being reported to them.

 

The S33 is a replacement for an earlier modem that I had. I worked with Comcast and we reinstalled that modem and everything worked fine so it doesn’t appear to be an issue with the connection from Comcast.  I use the previous modem for almost 8 years with no issues at all on the line.

 

Well, I checked the Event Log today and it seems that there are multiple errors and that the date of the device keeps getting reset to 12/31/1969… see the attached screenshot.

 

Please let me know how I can initiate warranty support for this before my warranty expires.

 

 

If the modem is rebooting on its own, could you confirm whether it is connected to a router or directly to a computer?

Additionally, if the signal levels are out of range, this could be causing the rebooting issue. I recommend checking the cable signal levels to ensure they are within the acceptable range:

Regarding the event logs, I suggest reaching out to your internet service provider, as the interruptions indicated in the logs may be related to signal issues.
