    Yes. Orbi supports any WAN connection that uses ethernet RJ45 connection. 

    Be sure your using good quality LAN cable between the modem and RBR. CAT6 is recommended. 

    Check with the ISP to see if there is any special configurations other than DHCP needed to be set on the Orbi system. Most Cable ISP use DHCP however could be something special needed. 

     

    If you connect a wired PC to the modem and power cycle it, does it get internet services thru the modem? If it doesn't, then it could be the modem. Connecting the RBR to the modem should use same power cycle on the modem to get it to connect to the RBR.
