DESCRIPTION
WLAN STA
Information
This section is available only when the NBG-418N is in universal repeater mode. This shows
the wireless and security settings of the selected AP wireless network.
SSID
This displays the Service Set IDentity of the wireless device to which you are connecting.
Security Mode
This displays the type of security configured on the wireless device to which you are
connecting.
Operating
Channel
This displays the channel used by the wireless device to which you are connecting.
WLAN AP
Information /
Wireless Setup
Use this section to configure the wireless settings between the NBG-418Nand its wireless
clients.
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 option for the NBG-418N to automatically choose the channel with the least
interference. Deselect this option if you wish to manually select the channel using the
Channel Selection
field.
Operating
Channel
This displays the channel the NBG-418N is currently using.
Channel Width
Select whether the NBG-418N uses a wireless channel width of
20MHz
,
40MHz
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-418N to
adjust the channel bandwidth automatically.
Security
Use this section to configure the wireless security between the NBG-418N and its wireless
clients.
Security Mode
Select
Static WEP
,
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
6.4.2
and
6.4.3
sections. Or you can select
No Security
to allow any client to
associate this network without authentication.

6.4.2
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-418N 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.
In order to configure and enable WEP encryption; click
Network
>
Wireless LAN
to display the
General
screen. Select
Static WEP
from the
Security Mode
list.

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-418N 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.

MAC Filter
The MAC filter screen allows you to configure the NBG-418N to give exclusive access to up to 16
devices (Allow) or exclude up to 16 devices from accessing the NBG-418N (Deny). Every Ethernet
device has a unique MAC (Media Access Control) address. The MAC address is assigned at the
factory and consists of six pairs of hexadecimal characters, for example, 00:A0:C5:00:00:02. You
need to know the MAC address of the devices to configure this screen.
To change your NBG-418N’s MAC filter settings, click
Network
>
Wireless LAN
>
MAC Filter
. The
screen appears as shown.
Table 29

LABEL
DESCRIPTION
Security Mode
Choose
WPA-PSK
or
WPA2-PSK
from the drop-down list box.
WPA Compatible
This option is available only when you select
WPA2-PSK
in the
Security Mode
field.
Select this option to have both WPA2 and WPA wireless clients be able to communicate
with the NBG-418N even when the NBG-418N is using WPA2-PSK.
Cipher Type
Select the encryption type (
TKIP
,
AES
or
TKIP+AES
) for data encryption.
Select
AES
if your wireless clients can all use AES. Otherwise, select
TKIP
or select
TKIP+AES
to allow the wireless clients to use either TKIP or AES.
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.
