Thanks. I just had a phone call with a Netgear support technician, who also concluded that the RBR LAN ports are bad. But, he was surprised, because he said he has never heard of this happening before, especially when all of the LAN ports on the device are failing.

Thanks. Will look into BYOD option. I also just found this thread on the Xfinity forum and wondering whether there is something in compatible between the Orbi and Xfinity device. https://forums.xfinity.com/conversations/your-home-network/xb7-with-orbi-rbr50-and-rbs50-in-access-point-mode-issue/602db12dc5375f08cd47ce10
