C3000 Wifi Drop-off Issue

TL;DR: The wifi drops off completely and doesn't link back to the Internet at least once a day, no power issues, no connectivity issues.

I have the C3000 DOCSIS 3.0 cable gateway on Comcast Xfinity, I'm not using a cable splitter or any other kind of product, my regular wifi download speed exceeds 15Mbps (occassionally goes up to 25Mbps). My wired connectivity hardly drops, but my wifi function has been malfunctioning at least once a day. A powercycle is the only way to fix this issue, and all my settings are under factory default setting, no modifications were done on the modem.

Here's what I did to triage the issue:

1. Changing channels after reboot - doesn't work, every channel drops off once in a while

2. Checked power issue, please see following chart for power levels:

3. Checked logs:

I've marked the time synchronize event to red because these are the exact time that my wifi function stopped working. I think this somehow indicates that either the initialization (causing the system time to revert back to 1970) or the synchronizing event are the root cause of drop offs. 

4. Last, you can see from the event log that it indicates a time sychronization failure, timestamp is always at 1970 since the modem was initialized back to 1970:

In all, I think this is a quality issue. I purchased this modem through Amazon in March, and this issue has been very persistent throughout my usage. I have ruled out Xfinity issues and my connected device issues. I hope Netgear can come up with some kind of a fix to this as this is proven to be a problem for many consumers.
