What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?
Something to contact Nintendo about regarding support of there product.

Its TMobile Home Internet, TMOG4AR. I had the Netgear R7000 before with same service provider with TMOG4AR without any problem. But after getting RS180, its pretty buggy. Even google Tvs having issues keeping stable connection.

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...
What is the ISP Speed UP and Down you pay for thru T-Mobile?

That is odd, and worth trying again.
Does the Nintendo work correctly when connected to the TMOG4AR wifi?
I am wondering why you are using the RS180, since the TMOG4AR is a reasonable dual-band WiFi 6 router.
