WEP is the wireless LAN security technology 
specified by IEEE802.11. It applies 
encryption to communications. There are two 
types of encryption key length; 64-bit key and 
128-bit key. The 128-bit encryption key 
assures a higher security level. A decryption 
technique exists, however, so using the same 
encryption key for an extended period of time 
is not recommended.

WPA is a security technology developed to 
correct for the deficiencies of WEP. The 
LocationFree Base Station utilizes WPA 
together with TKIP encryption. WPA-PSK 
with TKIP encryption assures the highest 
security level among the technologies 
supported by the LocationFree Base Station.

The security for wireless LAN 
communication is set to WEP as the factory 
default. To increase the security level, switch 
to WPA-PSK. Note, however, that the 
communication stability may differ 
depending on which technology you use, 
WEP or WPA-PSK.

• When choosing encryption keys and pre-shared 

keys, you should avoid words and phrases that are 
easy for other people to guess.

• For better security, you should change your 

encryption key or pre-shared key periodically.

• You will need the SSID, and the encryption key or 

pre-shared key, when you connect your computer to 
the Base Station via a wireless connection. Make a 
note of the information you enter here.

• The information set here is only used in normal 

mode. In setup mode, the initial settings shown on 
the side of the Base Station are used  (

and 14).

• Configuring the wireless settings on a computer 

connected to the Base Station via a wired LAN is 
recommended to ensure security. 

Also you can use the Base Station as a Wireless 
Access Point.
If you use the Base Station as a Wireless Access 
Point, you can connect to the Internet via the Base 
Station from a device equipped with a wireless 
LAN function.

To use the Base Station as a wireless access point for 
computers, the computers must be equipped with 
integrated wireless LAN functions or wireless LAN 
cards that conform to the IEEE802.11b/g standards.

• Not all wireless LAN devices can be guaranteed to 

connect to the Base Station.

• You can also connect a maximum of 16 wireless 

LAN devices by using the Base Station as an access 
point. In some cases, however, the number of 
connecting devices may cause the communication 
speed to decrease. For example, you may not be able 
to send or receive video smoothly if other wireless 
LAN devices connect and communicate with the 
Base Station.

To use a wireless LAN from a computer, you 
need a computer with a built-in wireless LAN 
function or a wireless LAN card that conforms to 
the IEEE802.11b/g standard. Next, you must 
configure the Windows environment settings, 
Internet connection settings, and wireless 
connection settings on your computer to match 
the wireless LAN settings of the Base Station, so 
that the computer can communicate with the Base 
Station (

For more information, refer to the user’s manual 
of your computer and the operating instructions 
that came with your wireless LAN card.
