3 CONFIGURATION GUIDE

The SMCWUSBS-N4 can be configured by the SMC Wireless N Client Utility
in Windows XP and 2000. This chapter describes how to configure your
adapter for wireless connectivity on your Wireless Local Area Network
(WLAN) and use the data security encryption features.

The configuration of the adapter in Windows XP is similar with that of
Windows 2000. This User Guide takes Windows XP for example.

FOR WINDOWS XP

After Installing the adapter, the adapter’s tray icon will appear in your
system tray. It appears at the bottom of the screen and shows the signal
strength using color based on the received signal strength indication
(RSSI).

Table 2: Signal Strength System Tray Icon

If the icon is gray, there is no connection.

If the icon is red, there is poor signal strength and the RSSI is
less than 5dB.

If the icon is yellow, there is poor signal strength and the RSSI
is between 5dB and 10dB.

If the icon is partly green, there is good signal strength and the
RSSI is between 10dB and 20dB.

If the icon is all green, there is excellent signal strength and the
RSSI is more than 20dB.

Adapter continuously for a short message response time.

◆ Network Type - There are basically two modes of networking:

■

Infrastructure - All wireless clients will connect to an access point or
wireless router.

◆ Wireless Mode - Specifies 2.4 GHz 150 Mbps, 2.4 GHz 54 Mbps or

2.4 GHz 11 Mbps operation in an access point network. The wireless
adapter must match the wireless mode of the access point with which it
associates.

◆ Wireless Mode when Starting an Ad Hoc Network - Specifies

2.4 GHz 54/11 Mbps to start an Ad Hoc network if no matching network
name is found after scanning all available modes. This mode also allows
the selection of the channel that the wireless adapter uses. The
channels available depend on the regulatory domain. If the adapter
finds no other ad hoc adapters, the channel that the adapter starts the
ad hoc network with will be selected automatically. The adapter must
match the wireless mode and channel of the clients to which it
associates.

◆ 802.11 Authentication Mode - Select which mode the adapter uses

to authenticate to an access point:

■

Auto - Automatic causes the adapter to attempt authentication
using “Shared,” but switches it to “Open” authentication if shared
fails.

■

Open - Open System enables an adapter to attempt authentication
regardless of its WEP settings. It will only associate with the access
point if the WEP keys on both the adapter and the access point
match.

■

Shared - Shared-key only allows the adapter to associate with
access points that have the same WEP key.

For infrastructure (access point) networks, click Preferred APs to specify
four access points at most to which the client adapter that attempts to be
associated. The four access points have different priorities; the first has the
higher priority.

GLOSSARY

IEEE 802.11B The 802.11b standard specifies wireless product networking at 11 Mbps

using direct-sequence spread-spectrum (DSSS) technology and operating
in the unlicensed radio spectrum at 2.4 GHz. It supports WEP encryption
for security. All 802.11 networks are also referred to as Wi-Fi networks.

IEEE 802.11G The specification for wireless networking at 54 Mbps using direct-sequence

spread-spectrum (DSSS) technology, using OFDM modulation and
operating in the unlicensed radio spectrum at 2.4 GHz. Includes backward
compatibility with IEEE 802.11b devices and WEP encryption for security.

AD HOC NETWORK An ad hoc network is a group of computers, each with a wireless adapter,

connected as an independent 802.11 wireless LAN. Ad hoc wireless
computers operate on a peer-to-peer basis, communicating directly with
each other without the use of an access point. Ad hoc mode is also referred
to as an Independent Basic Service Set (IBSS) or as peer-to-peer mode,
and is useful at a departmental scale or SOHO operation.

FHSS (FREQUENCY

HOPPING SPREAD

SPECTRUM)

DSSS generates a redundant bit pattern for all data transmitted. This bit
pattern is called a chip (or chipping code). Even if one or more bits in the
chip are damaged during transmission, statistical techniques embedded in
the receiver can recover the original data without the need of
retransmission. To an unintended receiver, DSSS appears as low power
wideband noise and is rejected (ignored) by most narrowband receivers.
However, to an intended receiver (that is, another wireless LAN endpoint),
the DSSS signal is recognized as the only valid signal, and interference is
inherently rejected (ignored).

FHSS continuously changes (hops) the carrier frequency of a conventional
carrier several times per second according to a pseudo-random set of
channels. Because a fixed frequency is not used, and only the transmitter
and receiver know the hop patterns, interception of FHSS is extremely
difficult.

INFRASTRUCTURE

NETWORK

An infrastructure network is a group of computers or other devices, each
with a wireless adapter, connected as an 802.11 wireless LAN. In
infrastructure mode, the wireless devices communicate with each other
and to a wired network by first going through an access point. An
infrastructure wireless network connected to a wired network is referred to
as a Basic Service Set (BSS). A set of two or more BSS in a single network
is referred to as an Extended Service Set (ESS). Infrastructure mode is
useful at a corporation scale, or when it is necessary to connect the wired
and wireless networks.

SPREAD SPECTRUM Spread Spectrum technology is a wideband radio frequency technique

developed by the military for use in reliable, secure, mission-critical
communications systems. It is designed to trade off bandwidth efficiency
for reliability, integrity, and security. In other words, more bandwidth is
consumed than in the case of narrowband transmission, but the trade off
produces a signal that is, in effect, louder and thus easier to detect,
provided that the receiver knows the parameters of the spread-spectrum
signal being broadcast. If a receiver is not tuned to the right frequency, a
spread-spectrum signal looks like background noise. There are two main
alternatives, Direct Sequence Spread Spectrum (DSSS) and Frequency
Hopping Spread Spectrum (FHSS).

SSID A Service Set Identification is a thirty-two character (maximum)

WEP (WIRED

EQUIVALENT PRIVACY)

WI-FI A trade name for the 802.11b wireless networking standard, given by the

alphanumeric key identifying a wireless local area network. For the wireless
devices in a network to communicate with each other, all devices must be
configured with the same SSID. This is typically the configuration
parameter for a wireless PC card. It corresponds to the ESSID in the
wireless access point and to the wireless network name. See also Wireless
Network Name and ESSID.

A data privacy mechanism based on a 64-bit, 128-bit, or 152-bit shared
key algorithm, as described in the IEEE 802.11 standard. To gain access to
a WEP network, you must know the key. The key is a string of characters
that you create. When using WEP, you must determine the level of
encryption. The type of encryption determines the key length; 128-bit
encryption requires a longer key than 64-bit encryption. Keys are defined
by entering a string in HEX (hexadecimal - using characters 0-9, A-F) or
ASCII (American Standard Code for Information Interchange –
alphanumeric characters) format. The ASCII format is provided so you can
enter a string that is easier to remember. The ASCII string is converted to
HEX for use over the network. Four keys can be defined so that you can
change keys easily.
