the operating system.
8 | Utility Configuration
When the utility program is running, there will be a quick launch icon in the lower right-hand
corner of the task bar. The icon will be GREEN if you have a good connection to a wireless
network. If it is red, you will need to verify the network settings and check to be sure that the
Wireless Access Point on your network is turned on. You may also need to re-position the Access
Point and place it in a higher position so that you are able to gain more wireless signal strength.
Double-click the quick launch icon in the system tray to bring up the Configuration Utility. This
provides quick access to management statistics and adapter settings.
The Configuration Utility includes the following tabs:
Status: Allows you to view/monitor network status, throughput, wireless mode, and TCP/IP
Information.
Site Survey: Displays all the Access Points within range of the wireless adapter's signal. Allows
you to configure and modify Profiles.
About: Shows the driver and utility version information.
Section 8.1 | Status
When the Configuration Utility is initialized, the Status window will be immediately shown. This
will show you the connection status of the wireless adapter. When you are connected to the
network, you will see the oscillating bars next to Signal Strength and the Status field will show
that it is "Associated" as well. The Network Connection will display "AP (Infrastructure)" when the
client is configured to connect to an Access Point. It will display "Ad Hoc" when the client is
configured to connect wirelessly to another wireless client.
Settings cannot be changed on this tab. This tab gives you the data you need to determine which
wireless network you are connected to and your connection speed. It also shows the SSID and
Transmission speed of that network, and it gives you TCP/IP information.
Section 8.2 | Site Survey
The Site Survey tab scans and displays all Access Points on the wireless LAN. Note that it will
display all 802.11a, 802.11b and 802.11g Wireless Access Points. The "Connection Mode" column
will allow you to identify the network type. To choose a network, simply double-click the
"Network Name". Then you will see a window similar to Figure 1.2. Just click [Yes] to connect to
the network. If the network is encrypted, you will be prompted to enter the appropriate keys.
The "Connection State" column represents the MAC address of the wireless network. Other
columns include "WEP", "Signal Strength", and "Channel".
The bottom window shows the Profiles that you have configured. You can create a new Profile by
clicking [New]. You can also modify or delete a selected profile. To modify settings, highlight the
desired profile and click the [Modify] button. See the Configuration section below for more
information.
Section 8.3 | Configuration
To change the settings, simply enter the new desired values and click the [OK] button. The
wireless adapter will automatically associate with the same channel that the network is using.
Network Name (SSID): This limit is 32 characters. Input the SSID of the wireless network you
want to connect to. If you will be roaming among multiple Access Points with different BSSID's,
leave the SSID blank to allow the client to connect to the access point with the highest signal
strength.
Network Connection: Specifies the mode of the network. Two options are "Infrastructure" and
"Ad Hoc".
Wireless Mode: The available options are "802.11g", "802.11b", "802.11a" or "Auto". "Auto"
allows the use of 802.11a, 802.11g or 802.11b mode.
802.11a Turbo Mode: This function disables or enables the 802.11a Turbo mode.
Ad Hoc Net Start: Specifies a Radio Frequency band to use to establish an Ad Hoc network if
no matching SSID (wireless network) is found. Four options are available: 802.11g, 802.11b,
802.11a, and 802.11a Turbo. If the SMC2336W-AG cannot link to your Adhoc network, it will
establish a new Adhoc network on the Radio Frequency band specified by this Adhoc Net Start
setting.
Check the [Enable Advanced Setting] checkbox in order to view the bottom portion of the
Configuration window.
Power Saving Mode: There are three available power management options: "Off", "Normal"
and "Maximum". In Ad Hoc mode, Power Savings function cannot be enabled.
Encryption Type: There are three available options: "WEP", "AES" and "Auto". WEP stands for
Wired Equivalent Privacy, and AES stands for Advanced Encryption Standard. AES provides a
much higher level of security. "Auto" allows the Adapter and AP to negotiate the encryption type.
If AES is not available, WEP is used. By default, the Adapter is set to "Auto" and will attempt to
use AES first. If the Access Point supports WEP only or is configured for WEP only, the Adapter
will automatically use WEP. See the Encryption section for more info.
Scan Mode: There are three available options: "Active Scan", "Passive Scan" and "Auto".
Transmit Power: There are five available options: "Full Power", "50% Power", "25% Power",
"12% Power" and "Lowest Power". Full Power is the default setting and this will ensure the
highest signal strength and link quality.
802.11b Range: There are two available options: "Normal Range" and "Extended Range".
802.11b Preamble: Allows Ad Hoc compatibility with other 2.4GHz devices. There are two
available options: "Short and Long" and "Long only".
QoS: You can disable or enable the Quality of Service (QoS) feature. QoS provides priority to a
certain pre-defined service such as voice or video. Please note that your Access Point must also
support QoS in order to take advantage of these features.
Domain: Select your location from the drop-down menu.
Section 8.4 | Encryption
For more secure data transmissions, you can enable the encryption by going to the Security tab
and clicking the [Enable Security] checkbox. Then enter the appropriate keys. The SMC2336WAG fully supports 64/128-bit WEP in 802.11b and 802.11g mode and 64/128/152-bit in 802.11a
mode. By default, the WEP is disabled.
For the HEX Key Format, the security is enabled by entering 10-digit keys for the 64-bit WEP
configuration, 26-digit keys for a 128-bit WEP configuration or 32-digit keys for a 152-bit WEP
configuration. For the ASCII Key Format, the security is enabled by entering 5-letter keys for 64bit WEP, 13-letter keys for 128-bit WEP or 16-letter keys for 152-bit WEP.
You may use the passphrase function when configuring encryption on 802.11b or 802.11g
networks. You must enter the same exact passphrase on every network node in order for WEP to
work properly.
Be sure to select the desired "Default Encryption Key" in the top right corner of the window.

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 EZ Connect
SMC2336W-AG Universal Wireless Cardbus Adapter, 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 card is securely seated in the PCMCIA or PCI slot. Check for any
hardware problems, such as physical damage to the card.
o Try the card in another PCMCIA or 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
manufacturer 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.
Remove 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 "SMC2336W-AG Universal Wireless Adapter" 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
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.

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.
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 - 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.
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.
- 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 (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
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.
- 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.
MAC Address
connected to a network.
MDI / MDI-X
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
- MAC (Media Access Control) A MAC address is the hardware address of a device
- Medium Dependent Interface - Also called an "uplink port," it is a port on a
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.
– (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.
PCI - Peripheral Component Interconnect - Local bus for PCs from Intel that provides a highspeed 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
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 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.
- A subnet mask, which may be a part of the TCP/IP information provided by your
- Transmission Control Protocol/Internet Protocol. This is the standard protocol for data
