Wan Drops on router
This is the first time i have ever had a problem with something where i have had to go to a community or forum for a issue but I'm one my last straw. just to start out i have a xfinity xb7 modem and a new rs300 nighthawk router for reference.
About 6 months ago i began to have internment disconnections to only the wan port of my router. it would be up for a few hours 1 or 2 and then drop for 5 to 10 seconds before switching back and restarting the uptime back to 0. i tried everything you could think of when it comes to simple things like new cables, firmware updates, resets all the somewhat simple stuff to no help with the issue. I've gone through techs through xfinity had wires replaced from the pole outside straight to the modem but the issue i keep having with is I've tried 3 different routers and it just keeps resetting the wan on every router. everything else seems to work for the most part but I'm at a lost as to what to do at this point because everything on xfinitys end they say is fine. i use the internet all most all day rather i am playing games or streaming and this issue has been causing nothing but issues and i honestly just dont know where to even start anymore.

Does the Internet LED on the router turn AMBER or RED when this happens?
What Firmware version is currently loaded?
Be sure your using a good quality LAN cable between the modem and router. CAT6A STP is recommended.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...If the WAN port keeps resetting on all the routers you have tested, then this is a ISP issue with there modem/gateway. This means there is a loss of internet connection between the router and the ISP modem/gateway. Something they need to look into.
