Netgear Orbi Router RBR40 will not connect to internet
I have a Netgear Orbi Router RBR40. Purchased new in August 2019. Router stopped working today. I have done a hard reset. Will not connect. Can I purchase a replacement base station without the 3...

What modem is it connected to? Not saying its a line issue but netgears don't play as nicely with double nat's (more than 1 routing device) as others do. If the modem has its own integrated routing functions, sometimes you just need to adjust a thing or to for it to show internet connectivity.

Hi
My ISP is Spectrum. We have a SMC Networks router (router only; does not include wifi) Model D3G 1604W. Purchased router from Spectrum in 2017. Has worked perfectly Orbi RBR40 since 2019. I don't think its' the router which is working fine with temporary Netgear NIghtwawk X6 which I am using until I replace Orbi.

That device causes a double nat.
When you connect the orbi to it, you either need to go into the SMC device and put the orbi's ip address into its DMZ or you need to put the orbi in AP mode. Otherwise you're in that double nat

Thank you for the response. Odd that it worked fine for three years. I will try those troubleshooting steps and see if that works.

The storm might have changed a setting in the smc device. It might have been setup with the netgears IP address in its dmz. Or it might have been in modem only modem (ideal option)

When you first set up a device like a router that runs the risk of "double NAT" it can try to help by setting itself up in ways that avoid potential conflicts.
For example, when you try to add a router to a modem/router, it can detect the IP address of the first router and allocate something other than the default to the new one.
So, if your modem/router has already squatted on 192.168.1.1 or 192.168.0.1 your new router may decided to use "10.0.0.1".
As plemans says, if your network has some sort of upset, maybe the power goes out and things start in the wrong order, the network gets confused about what sits on what address.
Setting things up from scratch, after a complete reset, might also tell things to go back to where they were before the upset.
If you have a backup of the previous settings from all your devices that might work too.

Thank you for the response. I have done a hard reset of the device back to factory conditions. Still does not connect. I think it's a defective router.
