I have seen this suggestion early on in other posts, but it was never clear to me why turning off the M1 Nighthawk's WIFI is suggested when plugging it's ethernet port into a another WIFI router's WAN/Internet (input) port. Can you explain the reasoning?
The way I have tried hooking this up on my end, my M1 Nighthawk's WIFI IP range is 192.168.2.20 - 192.168.2.99 and the WIFI router it is connected to has a WIFI IP range of 192.168.0.20 - 192.168.0.99. Based on this, there is no WIFI IP conflict. It is unclear why else we should consider turning off the M1 Nighthawk's WIFI.
In my mind, when you connect the Nighthawk M1 by its ethernet port to the WAN of another WiFi router, you are using the M1 as your Internet source (exactly like a DSL or Cable modem) and then connecting your devices to the WiFi router which creates your LAN, with some clients perhaps hard wired to ethernet ports and others via WiFi.
If you leave the WiFi on the Nighthawk M1 enabled, even using the SSID (wifi network name) as your existing WiFi router, then devices connecting to the M1 will be on a different network (192.168.2.0) than devices connected to your second WiFi router (192.168.0.0) and will not have access to any network resources on your second (existing) LAN (192.168.0.0). If there are no such resources that you care about, then leave the M1's WiFi enabled and it will provide you with just Internet access.
Regardless, your second WiFi router will also complain about double NAT unless you configure it to ignore double NAT.
