INTRODUCTION

Congratulations on your purchase of the NP642 108Mbps IEEE 802.11g Wireless PCI Card.

This manual is designed to help familiarise users with the product and offers detailed operational and installation instructions, so please keep it for future reference.

With the NP642 Wireless (IEEE 802.11g) PCI Card, a computer can communicate with the Network wirelessly. User-friendly utility software is bundled with the NP642 providing conﬁguration, monitoring and diagnostic options.

The NP642 provides data transfer rates of up to 108 Mbps, which is 10 times faster than most existing Wi-Fi wireless networks.

Designed to handle bandwidth-intensive applications and multimedia content, the NP642 eliminates the need for unsightly ethernet cables while providing fast and secure network transfer rates.

The NP642 has the most advanced security features available today with 128 bit WEP encryption and WPA security.

The Wireless PCI Card conﬁguration is easy to conﬁgure for peer-to-peer networks, suitable for a small number of users, or for full infrastructure networks that allow broad area roaming.

4 NP642 IEEE 802.11g PCI Adapter YML785 Rev1

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 NP642 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 NP642 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 NP642 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 Superseded by WPA and 802.11i but still in use.

NP642 IEEE 802.11g PCI Adapter 5 YML785 Rev1

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.

Static Electricity

Computers are very sensitive to static electricity which may be discharged

by the user when the internal circuitry is touched. Ensure that you have

discharged any static prior to touching the computer’s PCI slots and

to removing the NetComm NP642 from its static bag, by touching an

earthed object ﬁrst. This can be the computer’s Power Supply provided

the power is switched off at the wall, but the power cord is connected to

the power socket; static will be discharged through the power cord’s earth

connection.
