Description
Field
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
Coexistence
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)
Preamble Mode
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
at 100%.

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.
Note
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.

We recommend that when you use AP mode, you let the modem router get its IP address dynamically from your
existing router. However, if you are sure that must use a static IP address, you can specify a static IP address
from your existing router's LAN IP address pool. To specify static IP address for the modem router, do the
following:
a.
Select the
Use fixed IP Address (not recommended)
radio button.
A pop-up window opens.
b.
Enter all static IP addresses.

Set Up a WiFi Bridge
You can use the modem router as a WiFi bridge and connect multiple devices with WiFi at the faster 802.11ac
speed. To do this, you need a WiFi router or access point (AP) in addition to the modem router: One device is
connected to the Internet modem and the other one functions as a WiFi bridge.You can connect the modem router
to the Internet modem and use the router or AP as a WiFi bridge (assuming that the router or AP is capable of
functioning as a WiFi bridge), or the other way around—connect the router or AP to the Internet modem, and use
the modem router as a WiFi bridge. Of course, you can also use two modem routers for such a setup.

Figure 14. Bridge mode setup with an 802.11ac WiFi connection
Setting up a WiFi bridge with two modem routers offers the following benefits:
•
You can take advantage of gigabit WiFi speeds on current devices.
•
Use gigabit WiFi for applications such as video and gaming.
•
Connect multiple devices such as a NAS, Smart TV, NeoTV, Blu-ray player, and game consoles at gigabit WiFi
speeds using a WiFi link.
•
Avoid the need for separate WiFi adapters for each device.
For example, you could install the first modem router in a room such as a home office where your Internet connection
is located.
Then set up the second modem router as a WiFi bridge and place it in a different room such as the room where your
home entertainment center is located. Cable the modem router that functions as a WiFi bridge to your Smart TV,
DVR, game console, or Blu-ray player, and use its 802.11ac WiFi connection to the first modem router.
The modem router that is connected to the Internet modem does not require any special setup because the modem
router that functions as a WiFi bridge connects to an existing SSID as a WiFi client, just like any other WiFi clients.
To set up a modem router as a WiFi bridge:
1.
Make a note of the WiFi settings of the other modem router that is connected to the Internet modem.
You must know the SSID, WiFi security mode, WiFi password, and operating frequency (either 2.4 GHz or 5
GHz).
2.
Launch a web browser from a computer or WiFi device that is connected to the network of the modem router
that you are setting up as a WiFi bridge.
