Strict NAT | Internet Not Available

So for the past couple of months every night/morning around 1am-3am my xbox one drops my internet (wifi) and gives me a strict NAT, not allowing me to do anything online. I've called my ISP (comcast) and told them about the problem, however they stated that
I had no outages at the time and that my internet is working fine, however I've reset my router, opened my router, checked all the settings, etc. and can not find a solution to the problem. Any suggestions would be great.

360 = Open Nat Xbox One = Strict Nat

On the 360 I had an Open Nat and now on the One I have a Strict Nat. Nothing has changed about my Internet through the transition to the One. Anyone else having this problem or have a fix? No worries if not, being stuck with a Strict Nat won't kill me!

You may have a NAT type problem. Verify this in your network settings in your Xbox. Click on Advanced Setting and in the center of the picture you will see the NAT Type. If you have moderate or worse Strict, try to talk with your internet provider. Make
Open NAT available to you. In terms of all games, it's best.

I am already in a DMZ and like I said, my NAT type is always set to open, I know how to do that. However, around 1-3am EST it won't connect to my router and says there are no networks available when in fact it is working fine on all my other devices. I even
tethered my cell phone and connected to the internet, so I am confused and lost at this point.
