Orbi AC2200 will not connect to my Adtran ONT w/Centurylink GPON fiber

[loverobert90]

Howdy, 

I have the Orbi AC2200 base and satelite. I amn tryingt o use it to replace my Zyxel C3000Z provided by Centurylink. My setup should go like this.... Adtran ONT - ORBI - Satelite. My problem is that I am unable to connect my orbi via PPPOE using the credentials provided by my fiber ISP. Any idea on what I can do?

Modem Combo Units:
Couple of options,
1. Configure the modem for transparent bridge mode. Then use the Orbi router in router mode.
2. If you can't bridge the modem, disable ALL wifi radios on the modem, configure the modems DMZ for the IP address the Orbi router gets from the modem. Then you can use the Orbi router in Router mode.
3. Or disable all wifi radios on the modem and connect the Orbi router to the modem, LAN to LAN and configure AP mode on the Orbi router.
