Parameter Description
Bandwidth
The channel bandwidth for 802.11n standard in the 2.4GHz band
(the 2.4 GHz tab).
• 20 MHz: 802.11n clients operate at 20MHz channels.
• 20/40 MHz: 802.11n clients operate at 20MHz or 40MHz
channels.
• Auto: The router automatically chooses the most suitable
channel bandwidth for 802.11n clients.
The channel bandwidth for 802.11n and 802.11ac standards in 5GHz
band (the 5 GHz tab).
• 20 MHz: 802.11n and 802.11ac clients operate at 20MHz
channels.
• 20/40 MHz: 802.11n and 802.11ac clients operate at 20MHz
or 40MHz channels.
• 20/40/80 MHz: 802.11ac clients operate at 20MHz, 40MHz,
or 80MHz channels.
• Auto: The router automatically chooses the most suitable
channel bandwidth for 802.11n and 802.11ac clients.
Autonegotiation
20/40 (Coexistence)
Available on the 2.4 GHz tab.
Move the switch to the right to let the router automatically choose
the most suitable channel bandwidth (20MHz or 40MHz) for the
connected devices (this setting can substantially lower the data
transfer rate of your wireless network). The switch is displayed when
the 20/40 MHz or Auto value is selected from the Bandwidth
drop-down list.
TX power
The transmit power (in percentage terms) of the router.
Preamble
This parameter defines the length of the CRC block sent by the
router when communicating to wireless devices.
Select the needed value from the drop-down list.
• Auto: The length of the block is defined automatically.
• Long: The long block.
• Short: The short block (this value is recommended for
networks with high-volume traffic).
