Advanced Settings

Advanced > Wireless (2.4GHz or 5GHz) > Advanced
These settings are advanced options that can be configured to change advanced
wireless broadcast specifications. It is recommended that these settings remain set to
their default values unless you are knowledgeable about the effects of changing these
values. Changing these settings incorrectly can degrade performance.
 Channel Width: Select the appropriate channel width for your wireless network.
This setting only applies to 802.11n and 802.11ac. For greater 802.11n
performance, select Auto 20/40MHz (Options: 20MHz or Auto 20/40MHz). It is
recommended to use the default channel bandwidth settings.
For greater 802.11ac performance, select Auto 20/40/80MHz (Options: 20MHz,
Auto 20/40MHz, Auto 20/40/80MHz). It is recommended to use the default channel
width settings.
Note: Please note that the default settings may provide more stability than the
higher channel bandwidth settings such as Auto 20/40/80MHz for connectivity in
busy wireless environments where there are several wireless networks in the area.
o 20 MHz: This mode operates using a single 20MHz channel for wireless devices
connecting at 802.11n on both 2.4GHz and 5GHz. This setting may provide more

stability than 20/40MHz (Auto) for connectivity in busy wireless environments
where there are several neighboring wireless networks in the area.
o Auto 20/40MHz (11n) or Auto 20/40/80MHz (11ac): When this setting is active,
this mode is capable of providing higher performance only if the wireless devices
support the channel width settings. Enabling Auto 20/40MHz or Auto 20/40/80
MHz typically results in substantial performance increases when connecting an
802.11ac/n wireless client.
 20/40 Coexistence (2.4GHz only): 20/40 MHz Coexistence allows for the auto-
fallback from 40MHz to 20MHz channel width operation when neighboring 802.11
wireless networks are detected.
 MCS: Allows you to lock down the wireless transmission rate.
 BG Protection:
 Beacon Period: A beacon is a management frame used in wireless networks that
transmitted periodically to announce the presence and provide information about
the router's wireless network. The interval is the amount time between each
beacon transmission. Default Value: 100 milliseconds (range: 100-1000)
 DTIM: A DTIM is a countdown informing clients of the next window for listening to
broadcast and multicast messages. When the wireless router has buffered
broadcast or multicast messages for associated clients, it sends the next DTIM with
a DTIM Interval value. Wireless clients detect the beacons and awaken to receive
the broadcast and multicast messages. The default value is 1. Valid settings are
between 1 and 255.
 Fragment Threshold: Wireless frames can be divided into smaller units (fragments)
to improve performance in the presence of RF interference and at the limits of RF
coverage. Fragmentation will occur when frame size in bytes is greater than the
Fragmentation Threshold. This setting should remain at its default value of 2346
bytes. Setting the Fragmentation value too low may result in poor performance.
 RTS Threshold: The Request To Send (RTS) function is part of the networking
protocol. A wireless device that needs to send data will send a RTS before sending
the data in question. The destination wireless device will send a response called
Clear to Send (CTS). The RTS Threshold defines the smallest data packet size
allowed to initiate the RTS/CTS function. Default Value: 2347 (range: 1-2347)
 TX Power: This setting allows you to adjust the wireless transmit power to a lower
setting. In busy wireless environments, lowering the transmit power may improve
better performance and connectivity and decrease interference with neighboring
wireless networks.
 Short Preamble: Using a short preamble can potentially increase throughput as the
transfer time is 96 microseconds versus the more commonly used long preamble
