The SB8200 has 2x ethernet ports on it. It makes you think that you can connect 2 devices to it. But you can't. Comcast only supports 1 public IP address. so only one device can be connected.
Try powering off the sb8200 and the orbi. Give it a couple minutes. disconnect the ethernet from the sb8200. After a couple minutes power it on and let it boot up.
