Wireless Terminology
Wireless Standards
802.11, 802.11b and 802.11g all refer to a series of standards which govern a common
method of creating wireless local area networks (WLANs).
802.11b and 11g are the most common WLAN types, with 11g being the later and faster
of the two standards with a maximum transmission rate of 54Mbps.
The NP644 is faster again as it is built around a processor which ‘turbo-charges’
transmission rates up to 108Mbps.
802.11g is ‘backward compatible’ with 802.11b, which means that the two standards are
able to communicate, albeit at the lower 11Mbps rate of the 11b standard.
The NP644 can communicate with both kinds of device at their maximum rate, and with
other ‘turbo-charged’ devices at the much higher rate of 108Mbps.

Wireless Security Terms
The Advanced Features of the NP644 include the ability to select from several types of
Wireless Security.
WEP WEP stands for Wired Equivalent Privacy. Introduced with
802.11b, WEP uses encryption to protect data confidentiality
by way of pre-shared keys (passwords or pass-phrases) that are
entered at both ends. Superseded by WPA and 802.11i but still in
use.
WPA WPA stands for Wi-Fi Protected Access - authorizes and
identifies users based on a secret key that changes automatically
at a pre-defined interval. This is called TKIP (Temporal Key
Integrity Protocol) to change the temporal key every 10,000
packets (= unit of data.) Keys can either be pre-shared or
established by a RADIUS Server.
RADIUS RADIUS is part of 802.11i security; this is a wireless standard
which is only concerned with wireless security standards.
Authentication is based around a secure server with a challengeand-response method of interaction which verifies the identity
of the client wishing to connect to the network. If you wish to
connect to a RADIUS server ask the Network Administrator for
details. RADIUS servers are not usually used as part of home
networks.

INSTALLING THE NB644
Step 1 - Utility Installation
1. Before inserting the USB Adaptor, first install the Utility Program first. Make sure that
the 108Mbps Wireless Network USB Adaptor is NOT inserted into the USB slot in
your PC.
NOTE: All the screens of the installation procedure mentioned in
this manual are based on Windows XP. For other windows
operating systems, the procedures are the same but the
screens may vary slightly to those displayed in this manual.
2. Turn on the computer. Insert the CD into the CD-ROM Drive. Select “USB Adaptor”
and then select “Install”.
