Internet connectivity issue R6400v2
We're having issues with our Netgear Nighthawk. We cannot get the Internet light to switch from orange back to white, and CenturyLink is refusing to help us because the modem is not theirs. We've trie...
What modem/gateway is the router connected to from centurylink? they're known for installing modem/router combo devices and that'd put you in 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.
