Orbi RBR50 wired connection problems

[joeymichalec]

As of this week my 2017 orbi is not communicating with my wired devices (TiVo and iMac), however works perfectly with all wifi devices. As an example Netflix and Pandora work perfectly on all wireless diveces but not on the wired TiVo and iMac. I turned on and off the orbi and router, unpluged and restarted all devices. The orbi app recognizes the wired devices on the network but still all wired devices cannot download data. The iMac works perfectly on wifi. The TiVo box is working flawlessly to watch and record TV but cannot access apps or remote viewing.

To me it seems that you have another router in your network (e.g. the ISP Router).
Wireless devices get their gateway address during attach procedure, so these will safely get the Orbi as a gateway, but wired devices will connect to the router that will reply first.
Please make sure that your ISP Router is bridged if you want to keep Orbi in Router Mode or if not possible set Orbi in AP Mode.

I do have an ISP Router from ATT. However the wired devices are conected to the Orbi and use that as the gateway so all devices wired or not use the same IP Address and comunicate. It has worked for over a year with the current setup. I admittedly am over my head as a network specialist and 10 year cord cutter.

So I believe I'm bridged with all devices to the Orbi with the same IP address. How would I know this for certain? Forgive my ignorance but I only look into these things when I have a problem.

A simple way to check if you have double NAT is using traceroute.
Please open a Command Prompt on any computer attached to Orbi and type:
> tracert 8.8.8.8    (traceroute to Google’s DNS server)
1. If you see two private IP addresses listed in the first two hops then you have double NAT. Please check the model of your ISP modem and if you have a manual for it.
2. If you see only one private address and the second hop shows a public address, then you’re all good and we need then to troubleshoot further to find the root cause of the issue,

What Firmware is currently loaded?
What is the Mfr and model# of the ISP modem the NG router is connected too?
Is the Orbi system operating in Router or AP mode?
What is the Mfr and model# of the ethernet switch if one is in the configuration.
