Wireless LAN security function of the
LocationFree Base Station
•WEP
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-PSK with TKIP encryption
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.
Security settings of 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.
Notes
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.
z Tips
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 (1 pages 11
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.
z Tip
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.
Notes
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 (1 page 14).
For more information, refer to the user’s manual
of your computer and the operating instructions
that came with your wireless LAN card.
