Nighthawk CM1150V / Orbi RBR20 Networking Failure
Something that should be so simple it's driving me crazy. I have xFinity, regrettably, and have been using the Nighthawk CM1150V for almost 2 years. When I bought it I had already purchased the Orbi...
The CM1150V is the only device connected directly to xFinity (via coax). The Orbi isn't supported nor does it have a coax connection. I've tried removing everything from the other 3 ports on the nighthawk, and even removed the rj11 connection. The nighthawk comes up, the orbi router comes up, but nothing can get to the internet cause the orbi doesn't have an ip address, nor any other info that the nighthawk should have handed down via dhcp.
what firmware is on the orbi?
Try this.
Factory reset the orbi and the CM1150v. Push and hold reset for 7-15 seconds on both.
Power off the cm1150v and the orbi. Disconnect everything from both and wait several minutes.
then connect coax back to the cm1150V.
power it on and wait 2 minutes for it to fully boot.
Connect port 1 on it to the wan port on the RBR's Wan port.
then try going through setup on the RBR.
Some isp's take a while to reassign the public ip address. So sometimes you need to power it down/back up in proper sequence.
