9 | Troubleshooting

PCI Compatibility

• Early PCI BIOS versions do not properly support the new PCI specifications and may
“hang” when a network card driver tries to load. If this occurs, make sure your BIOS
correctly supports the PCI Local Bus Specification (v2.0 or later) and upgrade your
computer BIOS to the latest version

• Some PCI computers are not self-configuring and require you to perform some or all of
the following functions by motherboard jumper changes and/or BIOS Setup
configuration:

o Verify that the PCI slot is an enabled bus-master slot and not a slave PCI slot.

The SMC2602W must be installed in a PCI bus-master slot. In some computers
the PCI slot must be configured to enable bus mastering. Refer to your PC’s
manual and check the PCI BIOS Setup program to be sure the PCI slot is an
enabled bus-master slot.

o Make sure that your motherboard supports 3.3V PCI cards.
o In some computers, you may be required to disable Plug-and-Play in the BIOS

Setup program if resources are not properly assigned between the network card
and other installed cards.

o Some computers may require you to reserve interrupts and memory addresses

for installed ISA cards to prevent PCI cards from using the same settings. Refer
to your PC’s manual and check the PCI BIOS Setup program configuration
options for ISA cards.

o Make sure the PCI slot is configured to support INTA.
o Ensure that INTA for the slot is assigned to a free interrupt (IRQ) number.

Common Installation Problems

Problems are often caused by cabling errors, conflicts with other devices installed in the same
computer, or software that has been configured incorrectly. If you encounter a problem with the
SMC2602W, use the following checklists to identify and correct the problem.

• If you’re computer cannot find the SMC2602W, or the network driver does not install
correctly, check the following items before contacting SMC Technical Support

o Make sure the card is securely seated in the PCI slot. Check for any hardware

problems, such as physical damage to the card’s edge connector.

o Try the card in another PCI bus-master slot. If this fails, test the card in a

completely different system or try using a second SMC2602W in that particular
bus-master slot.

o Check for resource conflicts in the PCI configuration.
o Make sure your computer is using the latest BIOS available. Contact the

manufacturer of the computer or motherboard for information on updating the
BIOS (e.g. – Dell, Toshiba, etc)

o If there are other network cards in the computer, they may be causing conflicts.

Remove all other cards from the computer and test the SMC2602W separately. If
you continue to have problems, remove all cards except the SMC2602W and your
video card.

Network Connection Problems

There may be a network connection problem if the LED on the card does not light, or if you
cannot access any network resources from the computer. Check the following items before
contacting SMC Technical Support.

• Make sure the correct network card driver is installed for your operating system. If
necessary, try uninstalling and reinstalling the driver. To do this, first go into the Device
Manager, select Network Adapters, and remove the SMC adapter. Then open up your
Start Menu, go to Programs, click the "SMC2602W 11Mbps WLAN Utility" program folder
and choose "Uninstall". Reboot the machine when the uninstall is complete. Once you
have booted up again, the OS may ask for the SMC Driver CD again. Insert your Driver
CD and browse to the driver path again. Then install the utility program again.

• 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).

• 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.

10 | Frequently Asked Questions

• What is a Wireless LAN?

o A 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 other 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.).

• What is Ad-hoc?

o An 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 (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, and the 802.11a standard defines 54 Mbps
in the 5GHz band.

• What is Infrastructure?

o In 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.

• 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.

• 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?

o Authentication 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?

o The 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 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?

o Short for Wired Equivalent Privacy, WEP is a security protocol for wireless local

area networks (WLANs) defined in the 802.11b and 802.11a standards.

o 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.

o 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.

o 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).

12 | 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 signaling 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.

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.

– A Windows and OS/2 bitmapped graphics file format. Bitmap files provide formats for 2,

16, 256, or 16 million colors. It uses the extension .BMP.

- BSS stands for "Basic Service Set". It is an Access Point and all the LAN PCs that are

BSS
associated with it.

CSMA/CA

- Carrier Sense Multiple Access with Collision Avoidance

- Dynamic Host Configuration Protocol. This protocol automatically configures the TCP/IP

DHCP
settings of every computer on your home network.

- DNS stands for Domain Name System, which allows Internet host computers to have a

DNS
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.

- DSL stands for Digital Subscriber Line. A DSL modem uses your existing phone lines to

DSL
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-ID, SSID) stands for "Extended Service Set". More than one BSS is configured to

ESS
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.

- Central connection device for shared media in a star topology. It may add nothing to the

Hub
transmission (passive hub) or may contain electronics that regenerate signals to boost strength
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.

– The data fields in an MP3 that hold the artist name, track titles, album titles, genre, etc are

ID3
known as ID3 tags.

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.

- Internet Service Provider. An ISP is a business that provides connectivity to the Internet for

ISP
individuals and other businesses or organizations.

– Joint Photographic Experts Group. JPEG is a standard for compressing still images and it

JPEG
provides compression with ratios up to 100:1. File extensions are .JPG or .JPEG.

- A communications network that serves users within a confined geographical area. It is

LAN
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.

The message transfer is managed by a transport protocol such as TCP/IP and NetBEUI. The
physical transmission of data is performed by the access method (Ethernet, Token Ring, etc.),

which is implemented in the network adapters that are plugged into the machines. The actual
communications path is the cable (twisted pair, coax, optical fiber) that interconnects each
network adapter.

MAC Address

- MAC (Media Access Control) A MAC address is the hardware address of a device

connected to a network.

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.

– MPEG Audio Layer 3. This is an audio compression technology that is included in the

MP3
MPEG-1 and -2 specifications. MP3 encoding can allow you to compress CD-quality sound by a
factor of 12.

– Moving Pictures Experts Group. MPEG is a standard for compressing video. MPEG-1 can

MPEG
provide resolution of 352x240 at 30 frames/second (fps) with 24-bit color and CD-quality sound.
MPEG-2 can provide resolution of 704x480. MPEG uses the same intraframe coding as JPEG for
individual frames, but also uses interframe coding which can help to further compress the video
data, thereby reducing the overall size of the video.

– (Network Address Translation) This process allows all of the computers on your home

NAT
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.

- Peripheral Component Interconnect - Local bus for PCs from Intel that provides a high-

PCI
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.

- Point-to-Point Protocol over Ethernet. Point-to-Point Protocol is a method of secure data

PPPoE
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.

- Transmission Control Protocol - TCP and UDP (User Datagram Protocol) are the two

TCP
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.

- User Datagram Protocol - A protocol within the TCP/IP protocol suite that is used in place

UDP
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.
