Orbi AC3000 does not detect Cable Modem

[rbmattis]

Hi, My Orbi AC3000 will not connect to the internet.

I tried resetting my cable modem, then calling my ISP and remotely resetting it, nothing.

I've tried multiple ethernet cables, other routers, and directly connected devices to the cable modem confirming it's not a) the cable modem b) my internet connection c) the ethernet cable. I even tried setting the MAC address on my Orbi to that of my old Router, no luck.

I can access the Orbi, pair it with the Satellite, change settings, factory reset it, but getting it to connect to the internet, nada. The Error message is, "connect an ethernet cable." Trust me, I've tried checking all the cabling. Nada.

I might return it given the headache.

The modem is an Arris TM1602, ISP is Spectrum, Orbi Firmware is 2.3.1.60

and, the ethernet cable is connected from the WAN (yellow) port on the RBR50 to the modem?  Turn off both devices.  Turn on the modem and wait for it to stabilize.  Then, turn on the Orbi router.

Yep... That's what I did. The Orbi still doesn't detect internet.

What happens if you power OFF The modem for 1 minute fully. May need to pull the back up battery. Power back on. Factory reset the RBR and with a wired PC conected to the RBR, walk thru the setup wizard. Does the wizard detect internet here at all?
