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 Number) in the
devices. Then, they connect and set up a secure network by themselves. See how
to set up a secure wireless network using WPS in the
Section 6.2.1 on page 57
.

General Wireless LAN Screen
Use this screen to enable the Wireless LAN, enter the SSID and select the wireless
security mode.
Note: If you are configuring the NBG-416N from a computer connected to the wireless
LAN and you change the NBG-416N’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 NBG-416N’s
new settings.

The following table describes the general wireless LAN labels in this screen.
See the rest of this chapter for information on the other labels in this screen.
7.4.1
No Security
Select
No Security
to allow wireless stations to communicate with the access
points without any data encryption.
Table 23
Network > Wireless LAN > General
LABEL
DESCRIPTION
Enable
Wireless LAN
Click the check box to activate wireless LAN.
Name(SSID)
(Service Set IDentity) The SSID identifies the Service Set with which a
wireless station is associated. Wireless stations associating to the access
point (AP) must have the same SSID. Enter a descriptive name (up to 32
printable 7-bit ASCII characters) 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 NBG-416N to automatically choose the
channel with the least interference. Deselect this check box if you wish to
manually select the channel using the
Channel Section
field.
Operating
Channel
This displays the channel the NBG-416N is currently using.
Channel
Width
Select whether the NBG-416N uses a wireless channel width of
20MHz
or
Auto 20/40MHz
. A standard 20MHz channel offers transfer speeds of up
to 150Mbps whereas a 40MHz channel uses two standard channels and
offers speeds of up to 300 Mbps. Because not all devices support 40MHz
channels, select
Auto 20/40MHz
to allow the NBG-416N to adjust the
channel bandwidth automatically.
Security
Mode
Select
WPA-PSK
or
WPA2-PSK
to add security on this wireless network.
The wireless clients which want to associate to this network must have
same wireless security settings as this device. After you select to use a
security, additional options appears in this screen. See
7.4.2
and
7.4.3
sections. Or you can select
No Security
to allow any client to associate
this network without authentication.
Note: If you enable the WPS function, only
No Security
,
WPA-PSK
and
WPA2-PSK
are available in this field.

accessible to any wireless networking device that is within range.

7.4.2
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 NBG-416N 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.

WEP Encryption
Select
64-bit WEP
or
128-bit WEP
to enable data encryption.
Authentication
Method
Select
Auto, Open System
or
Shared Key
from the drop-down list
box.
This field specifies whether the wireless clients have to provide the WEP
key to login to the wireless client. Keep this setting at
Auto
or
Open
System
unless you want to force a key verification before
communication between the wireless client and the ZyXEL Device
occurs. Select
Shared Key
to force the clients to provide the WEP key
prior to communication.
ASCII
Select this option in order to enter ASCII characters as WEP key.
Hex
Select this option in order to enter hexadecimal characters as a WEP
key.
The preceding "0x", that identifies a hexadecimal key, is entered
automatically.
Key 1 to Key 4
The WEP keys are used to encrypt data. Both the NBG-416N and the
wireless stations must use the same WEP key for data transmission.
If you chose
64-bit WEP
, then enter any 5 ASCII characters or 10
hexadecimal characters ("0-9", "A-F").
If you chose
128-bit WEP
, then enter 13 ASCII characters or 26
hexadecimal characters ("0-9", "A-F").
You must configure at least one key, only one key can be activated at
any one time. The default key is key 1.

Compatible
This check box is available only when you select

field.
Select the check box to have both WPA2 and WPA wireless clients be
able to communicate with the NBG-416N even when the NBG-416N is
using WPA2-PSK.
Pre-Shared Key
WPA-PSK/WPA2-PSK
uses a simple common password for
authentication.
Type a pre-shared key from 8 to 63 case-sensitive
ASCII
characters
(including spaces and symbols).
Type a pre-shared key less than 64 case-sensitive
HEX
characters ("0-
9", "A-F").
Group Key
Update Timer
The
Group Key Update Timer
is the rate at which the AP (if using
WPA-PSK/WPA2-PSK
key management) or RADIUS
server (if using
WPA/WPA2
key management) sends a new group key out to all
clients. The re-keying process is the WPA/WPA2 equivalent of
automatically changing the WEP key for an AP and all stations in a
WLAN on a periodic basis. Setting of the
Group Key Update Timer
is
also supported in
WPA-PSK/WPA2-PSK
mode.
