By default, 20/40 MHz coexistence is enabled to prevent interference between WiFi networks
in your environment at the expense of the WiFi speed. If no other WiFi networks are present
in your environment, you can clear the Enable 20/40 MHz Coexistence check box to increase
the WiFi speed to the maximum supported speed.
This setting applies to the 2.4 GHz band only.Note
Enable 20/40 MHz
The CTS/RTS threshold (the default is 2347) and the preamble mode (the default is Automatic)
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.
CTS/RTS Threshold (1-2347)
You can lower the WiFi transmit power by selecting a value lower than 100% from the Transmit
Power Control menu.
The setting of 100% allows the modem router to use the maximum WiFi transmit power to
transmit WiFi packets. Reducing the transmit power can save the power consumption for the
modem router but also reduces the WiFi coverage. If you want to ensure maximum WiFi
coverage, we recommend that you leave the setting on the Transmit Power Control menu

Set Up the Modem Router as a WiFi Access Point Only
By default, the modem router functions as a modem, router, and WiFi access point (AP). You can change the
operation mode to a mode in which the modem router functions as a standalone AP on your existing network. For
AP mode, you must connect the modem router to the router on your existing network. In AP mode, features such
routing, firewall, and traffic meter are disabled on the modem router because these functions, if supported, are
performed by the router.
To avoid interference with the router to which you connect the modem router, we recommend
that you use different WiFi settings on the modem router functioning in AP mode and the
router. You can also turn off the WiFi radio on the router and use the modem router only for
WiFi client access.
To set up the modem router as an AP:
1. Use an Ethernet cable to connect the red Internet port of the modem router to a LAN port on the router.
2. Launch a web browser from a computer or WiFi device that is connected to the network.
