Use the Modem Router as a WiFi Access Point
You can set up the modem router to function as a WiFi access point (AP) on the same local 
network as another router. When the modem router functions as a WiFi AP, many 
router-related features are disabled.
Tip:
If you want to change the modem router’s function, use a wired connection 
to avoid being disconnected when the new function takes effect.
To set up the modem router as an AP:
1. 
Use an Ethernet cable to connect the Internet port of the modem router to a LAN port on 
the other router.
Cable the red Internet port
to a LAN port on another router
2. 
Launch a web browser from a computer or WiFi device that is connected to the network.
3. 
Type http://www.routerlogin.net.
A login window opens.
4. 
Enter the modem router user name and password.

2347), and the preamble mode (the default is Long Preamble) are reserved for WiFi 
testing and advanced configuration only. Do not change these settings unless 
directed by NETGEAR support or unless you are sure what the consequences are. 
Incorrect settings might disable the WiFi function of the modem router unexpectedly.
