By default, the
Enable Router’s PIN
check box is selected and the modem router’s PIN is
enabled. For enhanced security, you can disable the modem router’s PIN by clearing the
Enable Router’s PIN
check box. However, when you disable the modem router’s PIN,
WPS is not disabled because you can still use the physical
WPS
button.
Note:
The PIN function might temporarily be disabled automatically if the
modem router detects suspicious attempts to break into the modem
router’s WiFi settings by using the router’s PIN through WPS.

To allow the wireless settings for the 2.4 GHz radio to be changed automatically when you
use WPS, clear the
Keep Existing Wireless Settings (2.4GHz b/g/n)
check box.
8.
To allow the wireless settings for the 5 GHz radio to be changed automatically when you use
WPS, clear the
Keep Existing Wireless Settings (5GHz a/n)
check box.
By default, both
Keep Existing Wireless Settings
check boxes are selected. NETGEAR
recommends that you leave these check box selected. If you clear these check box, the
next time a new WiFi client uses WPS to connect to the modem router, the modem router
WiFi settings change to an automatically generated random SSID and passphrase. For
information about viewing this SSID and passphrase, see
Manage the Basic WiFi
Settings and WiFi Security of the Main Network
on page
56. Clear the
Keep Existing
Wireless Settings
check box for a radio only if you want to allow the WPS process to
change the SSID and passphrase for WiFi access for that radio.
WARNING:
If you clear the Keep Existing Wireless Settings check box for a
radio and use WPS to add a computer or WiFi device to the modem
router’s WiFi network, the SSID and passphrase are automatically
generated and other WiFi devices that are already connected to the
modem router’s WiFi network might be disconnected.

Manage Advanced WiFi Features
For most WiFi networks, the advanced WiFi features work fine and you do not need to
change the settings.
Tip:
If you want to change the WiFi settings of the modem router’s main
network, use a wired connection to avoid being disconnected when
the new WiFi settings take effect.

Except for the description of 20/40 MHz coexistence, the descriptions in the table (not the
settings onscreen) apply to both the Advanced Wireless Settings (2.4GHz b/g/n) section
and the Advanced Wireless Settings (5GHz
a/n) section.

Description
Enable 20/40 MHz
Coexistence
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.

Transmit Power
Control
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, NETGEAR recommends that you leave the
setting on the
Transmit Power Control
menu at 100%.

Manage Wi-Fi Multimedia Quality of Service
Wi-Fi Multimedia Quality of Service (WMM QoS) prioritizes WiFi voice and video traffic over
the WiFi link.
WMM QoS prioritizes WiFi data packets from different applications based on four access
categories: voice, video, best effort, and background. For an application to receive the
benefits of WMM QoS, WMM must be enabled on both the application and the client running
that application. Legacy applications that do not support WMM and applications that do not
require QoS are assigned to the best effort category, which receives a lower priority than
voice and video.
WMM QoS is automatically enabled for the modem router. However, you can disable WMM
QoS.
Note:
20/40 MHz coexistence applies to the 2.4 GHz band only.
The fragmentation length (the default is 2346), 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.
