Suddenly no internet connection nighthawk rs 300, ISP is working fine,
The product stopt passing through internet. The isp is working fine Tried factory reset, After it it said connected to internet for a moment and now dead again. What should I do?

Ok if it's in router mode, then use the Yellow WAN port. Even AP mode uses the Yellow WAN port.
I'd be sure the ISP router has the DMZ or IP-pass thru enabled for the RS router if it's in router mode.

First of all, thank you for replying me, i attached a Gif file showing the lights blinking. I'm still not having internet with this RS300. Althought the app says there is one.
Yesterday I changed back to my old Nighthawk R7000 ac 1900 and internet works perfectly. But that is not the solution I'm looking for.

I tried something new, I changed the connected port from "internet port" (where it worked without problems for 2 weeks or so) to "multi gig internet"-port 4. There it seams Internet is working fine.
It only says:
Error: Unable to establish WAN aggregation. (printscreen attached)

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.
