Orbi RBR750 - Samsung TV will not connect to WiFi

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. 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 Orbi 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 Orbi router gets from the modem. Then you can use the Orbi router in Router mode.
3. Or disable all wifi radios on the modem and connect the Orbi router to the modem, configure AP mode on the Orbi router.

Try option #2 first...

The default setting for an Orbi 750 system is for the RBR750 to be in 'router mode'***, which includes a DHCP server.

Some is definitely wrong with the Samsung TV.  I suggest unplugging the TV power temporarily and starting over with the WiFi setup.

 

As FURRYe38 mentioned, there are specific applications which are difficult to enable when the user has "two routers" (the AT&T and the Orbi in your case).  Internet search for "Double NAT" will provide examples.  Connecting a television to the internet is not one of those applications that would be affected by having two routers.

 

There is certainly nothing wrong with eliminating a Double NAT, but it does not seem to be pertinent to this problem.

 

*** The original post did not mention what 'mode' the Orbi RBR750 is in, but it would not matter.  If the Orbi is in access point (AP) mode, then DHCP requests would be passed to the AT&T router, which is "on".

Any progress on this?

I have Fiber Internet (ATT BGW320-500 Router) and connected my Orbi RBR750 Router to it. Everything connects to the Orbi WiFi without an issue. However, when I try to connect my Samsung TV to the Orbi WiFi, I get an error.

 

Error message says: IP Auto setting failed. Ensure that DHCP server is enabled on the wireless network, and then unplug and re-plug the wireless network.

 

I looked at the ATT Router settings and see that DHCP server is enabled.

 

Any thoughts on how I resolve this?

 

Thanks!
