Orbi RBR20 issues with Arris TG1682G Modem/Router for Xfinity.
Alright, yet another XFiniti issue post! Like many, I am having issues getting my mother's RBR20 to connect to the internet with the Xfinity Arris TG1682G Modem/Router. I have enabled Bridge mode...
Please make sure of the following
1. The Orbi "Internet/Yellow Port" is connected by ethernet cable to Arris TG1682G.
2. No other devices are connected to Arris TG1682G ethernet ports.
3. Arris TG1682G is in bridge Mode.
4. The Orbi is in router mode and setup to obtain WAN DHCP automatically.
5. Power off both devices. Power on Arris TG1682G first and wait until LEDs show active and Internet. The power on the Orbi.
Comcast/Xfinity like most ISPs only assigns an account 2 public IP addresses and only one can be assigned to a device connected to the ethernet ports. So if you have multiple devices connected to the Arris TG1682G they may be racing for that 1 public IP address.

Go back and check your Arris settings. The modem needs to be active and the LAN portion technically disabled. Make sure, after changing settings on the Arris, and before connecting the Orbi, you reboot the Arris. This way the Arris will obtain the info from the ISP and assign an IP address to the Orbi router.
Trust me, I have. I spent 3 1/2 hours yesterday troubleshooting this. The only setting change I am aware of that needs to be made is enabling bridge mode. If there is another setting change to be made, no one has discovered and posted about it, as far as I can tell. I scoured every possible setting that can be changed in the Arris TG1682G and there is no way for a home user to, say, disable the wireless transmitters short of enabling bridge mode. If anyone has any suggestions on what else can be fiddled with in the modem, I'd love to hear them.
