Every 24 hours at ~2am, my modem loses connection (Resetting the cable modem due to docsDevResetNow)

I have the same problem except mine resets at midnight (possibly because of different timezones).  Even worse than the nightly network disconnects the modem password is often reset to the factory default (which is well known-- it's in the manual-- and thus is a significant security flaw).  My "friends" in the digital age don't seem to care about my security or my user experience but at least they certainly care about taking my money (with friends like that....).

To make matters even worse, I was told to call the home network department (877-216-9014) and after a lengthy call it was first explained to me that this was how dhcp worked and it needed to occur each day so I asked if it could occur at a different time, say 4 AM.  it was then explained that this setting can indeed be changed within the modem but they can't do it for me because I'm not a home network program (or whatever it's called) subscriber.  This is a Cox modem which I purchased from Cox and they want me to pay for another subscription (to go along w/ my cable, phone and internet subscriptions) for Cox to fix the issue that Cox causes?!?!  That is, my home network configuration has nothing to do with this issue (except that the devices have this strange requirement where they'd like to use the internet... uninterrupted)-- it's all Cox!  Hilariously, I then asked if these magical settings were something that I could update but was told it's awfully complicated and I'd have trouble finding it but I should be able to find what I need in the manual (which of course the manual doesn't have any info related to this).

My guess is, even if I paid for the additional subscription Cox wouldn't be able to change the modem settings  but would happily take some more of my money.  FWIW, I've looked at every user editable option within the web admin pages of the modem and there is nothing relevant.  

I honestly don't know of any setting within the modem that could be changed to alter the likelihood or frequency of resets other than making sure it responds to WAN pings, which I think is on by default now anyway. We may be resetting CG3000s that don't respond to WAN pings to overcome a freezing issue. Other than that, the only reason for external resets would be things that can't be changed such as system maintenance, but that should not happen on a daily basis.
