Nighthawk RAX45 Turns off WiFi and internet connection LAN Ok

[Austin_007]

So ever since the last Firmware update in April, My RAX45 would turn off Internet connectivity and WiFi on its own sometime overnight.  I have to reboot the router and then everything is fine again.  So I started Tracking this in July, it happens Every 5 Days, like clockwork.  I tried changing the Netgear NTP server to a different one, but that didn't change the behavior.  So on Aug 7th after it shut down overnight again, I changed the Time Zone from -6 to -11  and Guess what, Now it does the shutdown in the morning @9:23am .  So the Router is definitely basing this behavior on the Time.   Question what hidden code have they put into the firmware that is causing this, and is it changeable?  If not can I roll back to the Previous Firmware which did not exhibit this behavior?  Help

What Firmware version is currently loaded?
What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?
Be sure your using a good quality LAN cable between the modem and router. CAT6 is recommended. 

Any Wifi Neighbors near by? If so, how many?

Has a factory reset and setup from scratch been performed since last update?

Firmware V1.0.11.112_2.0.77  As per Netgear Router Update

All my network is CAT 6, I run Netgear RAX45 in behind Service Provider Router, as I have for over 10 years now with different routers.

As stated this only started after the last firmware update.

When you say do a Factory Reset, will this change the firmware or only wipe out all my settings?

Can I roll back to Previous Firmware version, and if so , how?

If your ISP Modem already has a built in router and wifi. This would be a double NAT (two router) condition which isn't recommended. This would be a double NAT condition which isn't recommended. https://kb.netgear.com/30186/What-is-Double-NAT

Couple of options,
1. Configure the modem for transparent bridge or modem only mode. Then use the NG router in router mode. You'll need to contact the ISP for help and information in regards to the modem being bridged correctly.
2. If you can't bridge the modem, disable ALL wifi radios on the modem, configure the modems DMZ/ExposedHost or IP Pass-Through for the IP address the NG router gets from the modem. https://kb.netgear.com/25891/DMZ-on-NETGEAR-routers

3. Or disable all wifi radios on the modem and connect the NG router to the modem, LAN to LAN configure AP mode on the NG router.

Try option #2 first...

Based on your response to the ISP router, you may need to factory reset and setup from scratch. 

Yes it only clears any user configurations is all. 

Try the suggestions first before rolling back FW.

All radio's are disabled on the Provider Modem, Have DMZ Passthrough already as I don't want provider functions, So I will write down all my settings and try the Factory reset, then we'll know in 5 days, I guess.

Thanks

So this happens on every 5th day at 9:23AM always? 

Any Wifi Neighbors near by? If so, how many?

[Austin_007]

Yes after I started Tracking it's 5 days always, and it did change from 3:23am to 9:23 am when i changed the time from -6hrs to -11hrs just to see what would happen.  Crazy stuff.  No interference from neighbors, have done signal strength and bandwidth checks, all good.

So we'll see what happens in 5 days after i reset modem.

Would be interesting to know if this still happens if you change the ISP modem back to router mode, disable wifi radios and use the modems DMZ for the RAX router...

Definately try a factory reset on the RAX and setup from scratch. 

What is the Brand and model # of the ISP modem?

Update on testing.  So router reboot itself while I was doing changes on August 23 (last Tuesday) I then decided to turn off my site blocking of all the sites I had blocked, specifically some of my camera's like to reach out to China sites and get reply's. Since doing that the problem has not re occurred so far even though I have not done the factory reset yet, so I believe that there must be a buffer overflow occurring when the Blocked site list fills up.  Will keep testing and report as I nail down more specifics.
