default is 2347), and the preamble mode (the default is Long Preamble) are

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 router unexpectedly.

Use the Router as a WiFi Access Point Only
By default, the router functions as both a router and a WiFi access point (AP). You can
set up the router to function as an access point only and let it operate in the same local
network as another router. When the router functions as an access point only, many of
its router-related features are disabled.
Tip: If you want to change the router’s function, use a wired connection to avoid being
disconnected when the new function takes effect.
To change the router to access point mode only:
1.
Use an Ethernet cable to connect the yellow Internet port on the rear panel of the
router to a LAN port on the other router.
2.
Launch a web browser from a computer or mobile device that is connected to the
network.
3.
Enter http://www.routerlogin.net.
A login window opens.
4. Enter the router user name and password.
The user name is admin. The default password is password. The user name and
password are case-sensitive.
The BASIC Home page displays.
5. Select ADVANCED > Advanced Setup > Wireless Access Point.
The Wireless Access Point page displays.
6. Select the Enable Access Point Mode check box.
The page expands.
