Detecting new modem
I am running a Nighthawk router. My modem (Shaw Canada) is about to be upgraded. The first technician told me that the router would need to be manually configured to detect the new modem and its dns....
What modem is it connecting to?
If its a modem only device its pretty simple. power off the modem and the router with nothing connected, then power on the modem and wait 2 minutes, then connect the router and power it on.
But if its a modem/router combo device, then its a different issue.
Ok. I will try the suggested approach and see what happens.
Current router is Nighthawk AC1900 Smart Wifi Router (R7000).
Switch is D-Link.
The new modem setup arrives on Wednesday. It appears to be Gateway 2.0
from your specs, it appears to be a modem/router combo device. It'll cause a double nat in default mode.
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.
https://kb.netgear.com/26765/Which-features-are-disabled-on-my-NETGEAR-router-when-it-is-set-to-AP-ModeThank you. I vaguely recall that I had to set the modem to pass through mode before (~ 4 years ago). Right now all attached items are on the router none on the modem.
