with Microsoft for assistance on re-enabling the service.
•Make sure the computer and other network devices are
receiving power. If you suspect a power outlet to be faulty,
plug another device into it to verify that it is working.
•
If your wireless station cannot communicate with a computer
on the Ethernet LAN when configured for Infrastructure mode,
try changing the wireless channel on the AP. Make sure the
SSID is the same as that used by the AP for a station with
roaming disabled, or the same as that used by the AP's
in the extended service set (ESS).
34
Troubleshooting
•The Access Point you are trying to attach to is defective
or may not be configured properly to accept your signal.
Check with the administrator of your wireless network for
more information on connecting to the LAN. Also run the
necessary diagnostics on the AP to make sure the unit
is fully operational.
•If you cannot access the Internet, be sure to check with
the ISP for further instructions once the drivers for the
Wireless Card are installed properly.

FREQUENTLY ASKED
QUESTIONS
•What is a Wireless LAN?
oA local area network that transmits over the air typically
in an unlicensed frequency such as the 2.4GHz band.
A wireless LAN does not require lining up devices for line of
sight transmission like IrDA. Wireless access points (base
stations) are connected to an Ethernet hub or server and
transmit a radio frequency over an area of several hundred
to a thousand feet which can penetrate walls and
non-metal barriers. Roaming users can be handed off from
one access point to another like a cellular phone system.
Laptops use wireless network cards that plug into an existing
PCMCIA slot or that are self contained on PC cards, while
stand-alone desktops and servers use plug-in cards (ISA,
PCI, etc.).
other
•What is AD-HOC?
oAn AD-HOC network is a peer to peer network where all
the nodes are wireless clients. As an example, two PC's
with wireless adapters can communicate with each other
as long as they are within range. A wireless extension
point can extend the range of an AD-HOC network.
•What is the 802.11 standard?
o
A family of IEEE standards for wireless LANs first introduced
in 1997. 802.11 provides 1 or 2 Mbps transmission in the
2.4GHz band using either a frequency hopping modulation
39
Frequently Asked Questions
(FHSS) technique or direct sequence spread spectrum
(DSSS), which is also known as CDMA. The 802.11b
standard defines an 11 Mbps data rate in the 2.4GHz band,
802.11g-draft standard defines 54 Mbps in the 2.4GHz
band, and the 802.11a standard defines 54 Mbps in the
5GHz band.
•What is Infrastructure?
oIn order for your wireless components to interact with
traditional wired networks they need a media bridge to
translate for them. This is where INFRASTRUCTURE
or Network mode comes into play. An ACCESS POINT
is attached to the network using CAT-5 Ethernet cable
attaching to a hub, switch or another PC. Wireless PC's
can then communicate to Wired Ethernet computers
through this access point. The total range of the network
is limited to a radius around this Access Point. To increase
the range, extra Access Points may be wired into the
network. These Access Points talk to each other over
the hard-wired Ethernet cables however, they cannot
communicate wirelessly to one another and they must
be wired to the same network. Individual wireless PC's
can move between Access Points on the same network
seamlessly due to a feature called ROAMING.
40
•What is Tx Rate?
o
Tx-Rate or TRANSFER RATE is the current speed at which
the network component is operating. SMC-802.11b products
can operate at speeds of 1Mb, 2Mb, 5.5Mb, & 11Mbps.
A wireless card set to AUTO will attempt to connect at
whatever speed will give the best throughput on the network.
Frequently Asked Questions
•What is RTS Threshold?
o(Request To Send)
An RS-232 signal sent from the transmitting station to the
receiving station requesting permission to transmit. RTS is
a collision avoidance method used by all 802.11b wireless
networking devices. In most cases you will not need to
activate or administer RTS. Only if you find yourself in an
Infrastructure environment where all nodes are in range
of the Access Point but may be out of range of each other.
It is recommended to leave this setting at its default value
leaving this feature disabled.
•What is Authentication Algorithm?
oAuthentication Algorithm is the means by which one station
is authorized to communicate with another. In an Open
System, any station can request authorization in accordance
with the WECA standard. In a Shared key system, only
stations that possess a secret encrypted key may participate
in the network. This is a low level security key which allows
the equipment with the shared key algorithm to see each
other on the wireless LAN.
•What is DBI?
oThe ability of the antenna to shape the signal and focus
it in a particular direction is called Antenna Gain, and is
expressed in terms of how much stronger the signal in
the desired direction is, compared to the worst possible
antenna, which distributes the signal evenly in all directions
(an Isotropic Radiator). To express the relationship to the
Isotropic reference, this is abbreviated: dBi. The typical
omni-directional stick antenna is rated at 6-8 dBi, indicating

Frequently Asked Questions
that that by redirecting the signal that would have gone
straight up or down to the horizontal level, 4 times as much
signal is available horizontally. A parabolic reflector design
can easily achieve 24 dBi.
•What is WEP?
oShort for Wired Equivalent Privacy, WEP is a security
protocol for wireless local area networks (WLANs) defined
in the 802.11b and 802.11a standards.
WEP is designed to provide the same level of security
as that of a wired LAN. LANs are inherently more secure
than WLANs because LANs are somewhat protected by
the physicalities of their structure, having some or all part
of the network inside a building that can be protected from
unauthorized access. WLANs, which are over radio waves,
do not have the same physical structure and therefore are
more vulnerable to tampering.
WEP aims to provide security by encrypting data over radio
waves so that it is protected as it is transmitted from one
end point to another. The Wired Equivalent Privacy (WEP)
feature uses the RC4 PRNG algorithm developed by RSA
Data Security, Inc.
42
If your wireless access point supports MAC filtering, it is
recommended that you use this feature in addition to WEP
(MAC filtering is much more secure than encryption).
TERMINOLOGY
10BaseT
Physical Layer Specification for Twisted-Pair Ethernet using
Unshielded Twisted Pair wire at 10Mbps. This is the most popular
type of LAN cable used today because it is very cheap and easy
to install. It uses RJ-45 connectors and has a cable length span of
up to 100 meters. There are two versions, STP (Shielded Twisted
Pair) which is more expensive and UTP (Unshielded Twisted Pair),
the most popular cable. These cables come in 5 different categories.
However, only 3 are normally used in LANs, Category 3, 4 and 5.
CAT 3 TP (Twisted Pair) cable has a network data transfer rate
of up to 10Mbps. CAT 4 TP cable has a network data transfer rate
of up to 16Mbps. CAT 5 TP cable has a network data transfer
rate of up to 100Mbps.
Access Point
A device that is able to receive wireless signals and transmit
them to the wired network, and vice versa - thereby creating
a connection between the wireless and wired networks.
Ad Hoc
An ad hoc wireless LAN is a group of computers, each with
LAN adapters, connected as an independent wireless LAN.
Adapter
A device used to connect end-user nodes to the network;
each contains an interface to a specific type of computer
or system bus, e.g. EISA, ISA, PCI, PCMCIA, CardBus, etc.
Auto-Negotiation
A signalling method that allows each node to define its
operational mode (e.g. 10/100 Mbps and half/full duplex)
and to detect the operational mode of the adjacent node.
43
Terminology
Backbone
The core infrastructure of a network. The portion of the network
that transports information from one central location to another
central location where it is unloaded onto a local system.
Base Station
In mobile telecommunications, a base station is the central radio
transmitter/receiver that maintains communications with the mobile
radiotelephone sets within its range. In cellular and personal
communications applications, each cell or micro-cell has its own
base station; each base station in turn is interconnected with
other cells' bases.
BSS
BSS stands for Basic Service Set. It is an Access Point and all
the LAN PCs that are associated with it.
CSMA/CA (Carrier Sense Multiple Access with Collision
Avoidance)
DHCP (Dynamic Host Configuration Protocol)
This protocol automatically configures the TCP/IP settings
of every computer on your home network.
DNS
DNS stands for Domain Name System, which allows Internet host
computers to have a domain name (such as www.smc.com) and
one or more IP addresses (such as 192.34.45.8). A DNS server
keeps a database of host computers and their respective domain
names and IP addresses, so that when a domain name is requested
(as in typing "www.smc.com" into your Internet browser), the user
is sent to the proper IP address. The DNS server address used
by the computers on your home network is the location of the DNS
server your ISP has assigned.
44
Terminology
DSL
DSL stands for Digital Subscriber Line. A DSL modem uses
your existing phone lines to transmit data at high speeds.
Ethernet
A standard for computer networks. Ethernet networks are
connected by special cables and hubs, and move data around
at up to 10 million bits per second (Mbps).
ESS
ESS (ESS-ID, SSID) stands for "Extended Service Set". More
than one BSS is configured to become an Extended Service Set.
LAN mobile users can roam between different BSSs in an ESS
(ESS-ID, SSID).
Fast Ethernet NIC
Network interface card that is in compliance with the IEEE 802.3u
standard. This card functions at the media access control (MAC)
layer, using carrier sense multiple access with collision detection
(CSMA/CD).
Fixed IP
(see Static IP)
Full-Duplex
Transmitting and receiving data simultaneously. In pure digital
networks, this is achieved with two pairs of wires. In analog
networks, or digital networks using carriers, it is achieved by
dividing the bandwidth of the line into two frequencies, one for
sending, one for receiving.
Hub
Central connection device for shared media in a star topology.
It may add nothing to the transmission (passive hub) or may
contain electronics that regenerate signals to boost strength
45
Terminology
as well as monitor activity (active/intelligent hub). Hubs may be
added to bus topologies; for example, a hub can turn an Ethernet
network into a star topology to improve troubleshooting.
IP Address
IP stands for Internet Protocol. An IP address consists of a series
of four numbers separated by periods, that identifies an single,
unique Internet computer host. Example: 192.34.45.8.
ISP (Internet Service Provider)
An ISP is a business that provides connectivity to the Internet
for individuals and other businesses or organizations.
LAN
A communications network that serves users within a confined
geographical area. It is made up of servers, workstations,
a network operating system and a communications link. Servers
are high-speed machines that hold programs and data shared by
network users. The workstations (clients) are the users' personal
computers, which perform stand-alone processing and access
the network servers as required.
Diskless and floppy-only workstations are sometimes used, which
retrieve all software and data from the server. Increasingly, thin
client network computers (NCs) and Windows terminals are also
used. A printer can be attached locally to a workstation or to a
server and be shared by network users. Small LANs can allow
certain workstations to function as a server, allowing users access
to data on another user's machine. These peer-to-peer networks
are often simpler to install and manage, but dedicated servers
provide better performance and can handle higher transaction
volume. Multiple servers are used in large networks.
MAC Address MAC (Media Access Control)
A MAC address is the hardware address of a device connected
to a network.
46
Terminology
MDI / MDI-X (Medium Dependent Interface)
Also called an uplink port, it is a port on a network hub or switch
used to connect to other hubs or switches without requiring a
crossover cable. The MDI port does not cross the transmit and
receive lines, which is done by the regular ports (MDI-X ports)
that connect to end stations. The MDI port connects to the MDI-X
port on the other device. There are typically one or two ports on a
device that can be toggled between MDI (not crossed) and MDI-X
(crossed).
Medium Dependent Interface - X (crossed)
A port on a network hub or switch that crosses the transmit lines
coming in to the receive lines going out.
NAT (Network Address Translation)
This process allows all of the computers on your home network
to use one IP address. The NAT capability of the Barricade,
allows you to access the Internet from any computer on your
home network without having to purchase more IP addresses
from your ISP. Network Address Translation can be used to give
multiple users access to the Internet with a single user account,
or to map the local address for an IP server (such as Web or
FTP) to a public address. This secures your network from direct
attack by hackers, and provides more flexible management by
allowing you to change internal IP addresses without affecting
outside access to your network. NAT must be enabled to provide
multi-user access to the Internet or to use the Virtual Server
function.
Packet Binary Convulational Code(tm) (PBCC)
A modulation technique developed by Texas Instruments Inc.
(TI) that offers data rates of up to 22Mbit/s and is fully backward
compatible with existing 802.11b wireless networks.
47
Terminology
PCI (Peripheral Component Interconnect)
Local bus for PCs from Intel that provides a high-speed data path
between the CPU and up to 10 peripherals (video, disk, network,
etc.). The PCI bus runs at 33MHz, supports 32-bit and 64-bit data
paths, and bus mastering.
PPPoE (Point-to-Point Protocol over Ethernet)
Point-to-Point Protocol is a method of secure data transmission
originally created for dial-up connections. PPPoE is for Ethernet
connections.
Roaming
A function that allows your to move through a particular domain
without losing network connectivity.
Static IP
If your Service Provider has assigned a fixed IP address; enter
the assigned IP address, subnet mask and the gateway address
provided by your service provider.
Subnet Mask
A subnet mask, which may be a part of the TCP/IP information
provided by your ISP, is a set of four numbers configured like
an IP address. It is used to create IP address numbers used
only within a particular network (as opposed to valid IP address
numbers recognized by the Internet.
TCP/IP (Transmission Control Protocol/Internet Protocol)
This is the standard protocol for data transmission over the
Internet.
TCP (Transmission Control Protocol)
TCP and UDP (User Datagram Protocol) are the two transport
protocols in TCP/IP. TCP ensures that a message is sent
accurately and in its entirety. However, for real-time voice
and video, there is really no time or reason to correct errors,
and UDP is used instead.
48
Terminology
UDP (User Datagram Protocol)
A protocol within the TCP/IP protocol suite that is used in place
of TCP when a reliable delivery is not required. For example, UDP
is used for real-time audio and video traffic where lost packets are
simply ignored, because there is no time to retransmit. If UDP is
used and a reliable delivery is required, packet sequence checking
and error notification must be written into the applications.
