11 | Troubleshooting
Common Installation Problems
Problems are often caused by conflicts with other devices installed in the same computer, or software
that has been configured incorrectly. If you encounter a problem with the EliteConnect Universal
SMC2512W-AG 2.4GHz/5GHz High Power PCI Card, use the following checklists to identify and correct the problem.
• If your computer cannot find the Wireless Card, or the network driver does not install correctly,
check the following items before contacting SMC Technical Support
o Make sure the cards are securely seated in the PCI slot and PC Card socket slot.
Check for any hardware problems, such as physical damage to the cards.
o Try the card in another PCI slot. If this fails, test the card in a completely different
system or try using a second Wireless Card in that particular slot.
o Check for resource conflicts
o Make sure your computer is using the latest BIOS available. Contact the manufac-
turer of the laptop, 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. Re-
move all other cards from the computer and test the Wireless Card separately.
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 shut down your machine and remove your SMC adapter. Then boot up and open up your Start Menu, go to Programs, click
the "SMC2536W-AG WLAN Utility" program folder and choose "Uninstall". Reboot the machine when requested to do so. Then insert your Driver CD and run the Setup.exe utility again.
Then shut down the computer, reinsert your SMC adapter and boot up the machine. The OS
should properly reinstall the adapter during this time.
• 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 con-
figured 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.

13 | Frequently Asked Questions
What is a Wireless LAN?
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?
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?
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, 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?
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?
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?
(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?
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.
43
What is DBI?
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?
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.
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.
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).

14 | Terminology
10BaseT
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.

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 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 sepa-
rated 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 indi-
viduals 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.
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 Instru-
ments Inc. (TI) that offers data rates of up to 22Mbit/s and is fully backward compatible with existing
802.11b wireless networks.
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.
46
- Point-to-Point Protocol over Ethernet. Point-to-Point Protocol is a method of secure data
PPPoE

- 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.
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.
