Guest WLAN Bandwidth
The Guest WLAN Bandwidth function allows you to restrict the maximum bandwidth for the guest
wireless network. Additionally, you can also define bandwidth for your home or office network. An
example is shown next to define maximum bandwidth for your networks (
A
is Guest WLAN and
N
is
home or company network.)

WPS
WiFi Protected Setup (WPS) is an industry standard specification, defined by the WiFi Alliance. WPS
allows you to quickly set up a wireless network with strong security, without having to configure
security settings manually. Depending on the devices in your network, you can either press a
button (on the device itself, or in its configuration utility) or enter a PIN (Personal Identification

General Wireless LAN Screen
Use this screen to configure the SSID and wireless security of the wireless LAN.
Note: If you are configuring the NBG6716 from a computer connected to the wireless LAN
and you change the NBG6716’s SSID, channel or security settings, you will lose
your wireless connection when you press
Apply
to confirm. You must then change
the wireless settings of your computer to match the NBG6716’s new settings.

off.
You can enable or disable both 2.4GHz and 5GHz wireless LANs by using the
WIFI
button
located on the side panel of the NBG6716.
Name (SSID)
The SSID (Service Set IDentity) identifies the Service Set with which a wireless client is
associated. Enter a descriptive name (up to 32 printable characters found on a typical
English language keyboard) for the wireless LAN.
Hide SSID
Select this check box to hide the SSID in the outgoing beacon frame so a station cannot
obtain the SSID through scanning using a site survey tool.

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.
802.11ac
: allows only IEEE 802.11ac compliant WLAN devices to associate with the
NBG6716.

WEP Encryption
WEP encryption scrambles the data transmitted between the wireless stations and the access points
to keep network communications private. It encrypts unicast and multicast communications in a
network. Both the wireless stations and the access points must use the same WEP key.
Your NBG6716 allows you to configure up to four 64-bit or 128-bit WEP keys but only one key can
be enabled at any one time.
Select
Static WEP
