Chapter 11 Wireless LAN Table 31 Network > Wireless LAN 2.4G/5G > General (continued) LABEL DESCRIPTION Channel Selection Set the operating frequency/channel depending on your particular region. Select a channel from the drop-down list box. The options vary depending on the frequency band and the country you are in. Auto Channel Selection Operating Channel Channel Width Refer to the Connection Wizard chapter for more information on channels. This option is only available if Auto Channel Selection is disabled. Select this check box for the NBG6716 to automatically choose the channel with the least interference. Deselect this check box if you wish to manually select the channel using the Channel Selection field. This displays the channel the NBG6716 is currently using. Select the wireless channel width used by NBG6716. A standard 20MHz channel offers transfer speeds of up to 144Mbps (2.4GHz) or 217Mbps (5GHZ) whereas a 40MHz channel uses two standard channels and offers speeds of up to 300Mbps (2.4GHz) or 450Mbps (5GHZ). An IEEE 802.11ac-specific 80MHz channel offers speeds of up to 1.3Gbps. Because not all devices support 40 MHz and/or 80 MHz channels, select Auto 20/40 MHz or Auto 20/40/80 MHz to allow the NBG6716 to adjust the channel bandwidth automatically. 40 MHz (channel bonding or dual channel) bonds two adjacent radio channels to increase throughput. A 80 MHz channel consists of two adjacent 40 MHz channels. The wireless clients must also support 40 MHz or 80 MHz. It is often better to use the 20 MHz setting in a location where the environment hinders the wireless signal. 802.11 Mode Select 20 MHz if you want to lessen radio interference with other wireless devices in your neighborhood or the wireless clients do not support channel bonding. If you are in the Wireless LAN 2.4G > General screen, you can select from the following: • 802.11b: allows either IEEE 802.11b or IEEE 802.11g compliant WLAN devices to associate with the NBG6716. In this mode, all wireless devices can only transmit at the data rates supported by IEEE 802.11b. • 802.11g: allows IEEE 802.11g compliant WLAN devices to associate with the Device. IEEE 802.11b compliant WLAN devices can associate with the NBG6716 only when they use the short preamble type. • 802.11bg: allows either IEEE 802.11b or IEEE 802.11g compliant WLAN devices to associate with the NBG6716. The NBG6716 adjusts the transmission rate automatically according to the wireless standard supported by the wireless devices. • 802.11n: allows IEEE 802.11n compliant WLAN devices to associate with the NBG6716. This can increase transmission rates, although IEEE 802.11b or IEEE 802.11g clients will not be able to connect to the NBG6716. I • 802.11gn: allows either IEEE 802.11g or IEEE 802.11n compliant WLAN devices to associate with the NBG6716. The transmission rate of your NBG6716 might be reduced. • 802.11 bgn: allows IEEE802.11b, IEEE802.11g and IEEE802.11n compliant WLAN devices to associate with the NBG6716.

Channel Selection
Set the operating frequency/channel depending on your particular region.
Select a channel from the drop-down list box. The options vary depending on the
frequency band and the country you are in.
Refer to the Connection Wizard chapter for more information on channels. This option is
only available if
Auto Channel Selection
is disabled.
Auto Channel
Selection
Select this check box for the NBG6716 to automatically choose the channel with the least
interference. Deselect this check box if you wish to manually select the channel using the
Channel Selection
field.
Operating
Channel
This displays the channel the NBG6716 is currently using.
Channel Width
Select the wireless channel width used by NBG6716.
A standard 20MHz channel offers transfer speeds of up to 144Mbps (2.4GHz) or 217Mbps
(5GHZ) whereas a 40MHz channel uses two standard channels and offers speeds of up to
300Mbps (2.4GHz) or 450Mbps (5GHZ). An IEEE 802.11ac-specific 80MHz channel offers
speeds of up to 1.3Gbps.
Because not all devices support 40 MHz and/or 80 MHz channels, select
Auto 20/40
MHz
or
Auto 20/40/80 MHz
to allow the NBG6716 to adjust the channel bandwidth
automatically.
40 MHz
(channel bonding or dual channel) bonds two adjacent radio channels to increase
throughput. A
80 MHz
channel consists of two adjacent 40 MHz channels. The wireless
clients must also support
40 MHz
or
80 MHz
. It is often better to use the 20 MHz setting
in a location where the environment hinders the wireless signal.
Select
20 MHz
if you want to lessen radio interference with other wireless devices in your
neighborhood or the wireless clients do not support channel bonding.
802.11 Mode
If you are in the
Wireless LAN 2.4G > General
screen, you can select from the
following:
802.11b
: allows either IEEE 802.11b or IEEE 802.11g compliant WLAN devices to
associate with the NBG6716. In this mode, all wireless devices can only transmit at
the data rates supported by IEEE 802.11b.
802.11g
: allows IEEE 802.11g compliant WLAN devices to associate with the Device.
IEEE 802.11b compliant WLAN devices can associate with the NBG6716 only when
they use the short preamble type.
802.11bg
: allows either IEEE 802.11b or IEEE 802.11g compliant WLAN devices to
associate with the NBG6716. The NBG6716 adjusts the transmission rate
automatically according to the wireless standard supported by the wireless devices.
802.11n
: allows IEEE 802.11n compliant WLAN devices to associate with the
NBG6716. This can increase transmission rates, although IEEE 802.11b or IEEE
802.11g clients will not be able to connect to the NBG6716. I
802.11gn
: allows either IEEE 802.11g or IEEE 802.11n compliant WLAN devices to
associate with the
NBG6716. The transmission rate of your
NBG6716 might be
reduced.
802.11 bgn
: allows IEEE802.11b, IEEE802.11g and IEEE802.11n compliant WLAN
devices to associate with the NBG6716. The transmission rate of your NBG6716 might
be reduced.
If you are in the
Wireless LAN 5G > General
screen, you can select from the following:
802.11a
: allows only IEEE 802.11a compliant WLAN devices to associate with the
NBG6716.
802.11an
: allows both IEEE802.11n and IEEE802.11a compliant WLAN devices to
associate with the NBG6716. The transmission rate of your NBG6716 might be
reduced.
