The settings for LAN Setup of the Wireless Access Point can be viewed and changed here.
After applying the settings, remember to reboot the Access Point to save your settings.

15
3-3 Wireless Setup
Wireless LAN
The Wireless LAN Setup page lets you make changes to the wireless network settings. From
this window you can make changes to the wireless network name Country / Region,
Operating Mode, SSID, Broadcast SSID, WirelessMode, Channel/Frequency, Data Rate,
and Output Power.
Country / Region: Allow you to select country domain in case there is any chances that you
would use wireless network in other countries. They are Australia, Austria, Canada, China,
Denmark, Finland, France, Germany, Greece, Hong Kong, Iceland, Ireland, Italy, Japan,
Liechtenstein, Luxembourg, Netherlands, New Zealand, Norway, Portugal, Singapore, Spain,
Sweden, Switzerland, Taiwan, United Kingdom, United States.
Operating Mode: There are two operating modes: Access Point and Station Adapter. Not
only this device can be configured to work as a wireless network access point but also it can
be acting as a wireless client. To switch the mode, select the desired mode from the
down-arrow menu.
SSID: The SSID is a unique ID used by Access Points and Stations to identify a wireless
LAN. Wireless clients associating to any Access Point must have the same SSID. The default
SSID is “Access Point”. To change the SSID, type in the SSID you like to use. It is case
sensitive and must not exceed 32 characters.

16
Broadcast SSID:For security concern, you can choose not to broadcast your network’s SSID.
To turn off the broadcast of the SSID, click “No”check box next to “Broadcast SSID”. And
your Access Point will refuse the connection requestsfrom whose are not aware the Network
ID. But certainly the Access Point can be easily connected well when you realize the Network
ID. The default setting is “Yes”.
Wireless Mode: There are three different wireless modes to operate, “Auto (802.11g and
802.11b)”, “802.11b Only”, and “802.11g Only”. In Auto (802.11g and 802.11b) mode, the
access point is compatible with a mix of both 802.11g and 802.11b clients. You will see that
the factory-set default “Auto (802.11g and 802.11b)”will prove the most efficient.
802.11b-Only mode is compatible with 802.11b clients only. This mode can be used only if
you do not allow any 802.11g clients to access to the network. 802.11g-Only mode is
compatible with 802.11g clients only. This mode can be used only if you do not allow any
802.11b clients to access to the network. To switch the mode, select the desired mode form
the pull-down menu next to “Wireless Mode”.
Channel / Frequency: Select the appropriate channel/Frequency from the list provided to
correspond with your network settings.
Date Rate: The basic transfer rates should be set depending on the speed of your wireless
network. Specifies rate of data transmission. Select the desired rate from the drop-down menu
and choose “Best”to adapt the rate to the best available.
Output Power: Set the transmit signal strength of the access point. The options are Full, 50%,25%,
12.5%, and Min. Decrease the transmit power if necessary. The default is “Full”.
Note: If you complete the settings, please click on “Apply” and then “Reboot”for changes to
take effect.

17
Security Settings
To prevent unauthorized wireless stations from accessing data transmitted over the network,
the 802.11g SMB Wireless Access Point WEP Security Configuration window offers data
encryption, known as WEP (Wired Equivalent Privacy), making your data transmission over
air more secure and allows you to specify Encryption Key(s) if you enable encryption for the
802.11g SMB Wireless Access Point.
For a step-by-step treatment of security configuration, please do the following:
1. Choose the Authentication Type
To set authentication for 802.11g band, you can select Open System or Shared Key
Authentication Type by selecting the radio button. All other devices using this band must
share this setting. Shared Key operation offers a step up in security over Open System
operation.
Open System: Requires NO authentication, since it allows any device to join a network
without performing any security check. The Authentication Type default is set to “Open
System”. We recommend that you use the default setting.
Shared Key: Requires that the station and the access point use the same WEP key to
authenticate. This basically means that WEP must be enabled and configured on both the
access point and the client with a same key. All points on your network must use the same
authentication type.

18
2. Select the Encryption Strength
For 802.11g, you must have four Encryption Keys set, and all keys must have the same
encryption strength. Your Access Point can operate in four different encryption strength,
“none”, “64-bit”, “128-bit”, and “152-bit”.
3. Set up Security Encryption Keys
There are two methods for creating WEP data encryption:
lUsing a Passphrase: Type in a passphrase and click “Generate Keys”. Passphrase can
be a mixture of numbers and letters. When entering passphrase, you must not exceed 32
characters. As you type, the wireless stationadapter will use an algorithm to generate 4
keys automatically. Select one key from the 4 WEP keys.
lManually:
64 bits WEP: Enter 10 hexadecimal digits (between 0-9, a-f and A-F)
128 bits WEP: Enter 26 hexadecimal digits (between 0-9, a-f and A-F)
152 bits WEP: Enter 32 hexadecimal digits (between 0-9, a-f and A-F)
Note: The WEP key must be set up exactly the same on the Wireless Access Points as they
are on the wireless clients. If you set “0011223344” for the Wireless Access Point, the same
WEP key “0011223344”must be assigned to other client stations.
4. Enable Wireless Client Security Separator
Enable this function to let associated clients be able to separate from each other when security
is required. The default setting is Disable.
Note: If you complete the settings, please click on “Apply” and then “Reboot”for changes to
take effect.

19
Access Control
The Access Controlallows you to restrict wireless access by MAC Address. This provides an
additional layer of security. Follow these steps:
1. In 802.11g SMB Wireless Access Point’s left page, choose the Access Control option from
the Wireless Setup.
2. If you want to enable filtering of computer by their MAC Address, click the check box
next to “Turn Access Control on”.
3. Then, either select form the list of available wireless stations that your Access Point has
found or enter the MAC address for each client. After enter the MAC Address, click
“Add”button in the MAC Address field to be managed.
4. Click “Delete”button if you wish to remove the MAC address from the list.
5. If you complete the settings, please click on “Apply” and then “Reboot”for changes to
take effect.
