Can't Connect Orbi to Modem.

1. Can't connect Orbi AC1200 to (Centurylink) C3000A Modem. The internet feed comes to the modem on an ethernet cord . Plugged into the ethernet port titled "internet". There are 4 additional ethier net ports for various assorted gadgets.

I purchased a AC1200 Orbi router with 2 satellites.

Following instructions I opened the ORBI app and followed the instructions, (more than once). The result was "Can Not connect ORBIXX"

Question 1. Doest the ORBI Ethernet cord conect to one of the existing ethiernet ports, since the internet port is taken by the internet feed.??? 

Any help would be appreciated...

  • the one from centurly link is a modem/router combo device. 

    it causes a double nat. 

    A double nat happens when you cascade more than 1 router.

    Fixes? There’s 3 options but only use 1.
    1. Put the modem/gateway in modem only/pass through mode. This disables its routing functions.
    2. Leave the modem/gateway in router mode but put the Netgears IP address into its DMZ. This forwards the data to the netgear. You can either leave the modem/gateway’s wireless enabled or disabled. Just make sure its using a different wifi channel to prevent interference
    3. Put the Netgear into access point mode. This disables its routing functions. Wifi/ethernet still works but it does disable some features.
