Manage the WiFi Network Settings
N600 and AC750 WiFi DSL Modem Routers
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.
Enable 20/40 MHz
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
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 if the wireless mode is set to Up to 54 Mbps. For more information about how to change
the wireless mode, see View or Change the Basic WiFi Settings on page 56.
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.
