Authentication Type – WPA-PSK (Wi-Fi Protected Access-Pre
Share Key) and WEP (Wired Equivalent Privacy) are
implemented in the SMC2862W-G adapter to prevent
unauthorized access.
WPA-PSK
How to set up WPA:
Wi-Fi Protected Access is a standards-based, interoperable
security enhancement that strongly increases the level of data
protection and access control for existing and future wireless LAN
systems. It will be forward-compatible with the upcoming
IEEE 802.11i standard. WPA employs a combination of several
technologies to provide an enhanced security solution for 802.11
wireless networks, including TKIP (Temporal Key Integrity
Protocol) for data protection and 802.1x for authenticated key
management. WPA provides a simple operating mode that uses
just a pre-shared password for network access. The Pre-Shared
Key mode uses a common password for user authentication that
is manually entered on the access point and all wireless clients
on the network.
To use the WPA function, take the following steps:
1. Select Authentication Type, WPA-PSK from the drop-down
menu.
2. Type in the Pre-Shared Key (PSK).
3. Click Apply Change to allow the settings to take effect.
Note: The PSK Passphrase character limit needs to be between 8-63
characters.
Manual Pre-Shared Key supports up to 64-Hex characters. If
there is no authentication server on your SOHO network, you can
issue the Pre-Shared Key to the adapter that is connected to the
access point. Be sure to use the same key for the wireless access
point and the connected adapter.
Configuration
17
For enterprise deployment, WPA requires a RADIUS
authentication server to be configured on the wired network. The
802.1x client and RADIUS server should use an appropriate EAP
type - such as EAP-TLS (Transport Layer Security), EAP-TTLS
(Tunneled TLS), or PEAP (Protected EAP) - for strongest
authentication. Working together, these protocols provide “mutual
authentication” between a client, the access point, and a RADIUS
server that prevents unauthorized users from joining your
network, and also prevents users from accidentally joining a
rogue network. Only when a RADIUS server has authenticated a
user’s credentials will encryption keys be sent to the access point
and client.
Note: To implement WPA on wireless clients requires a
WPA-enabled network card driver and 802.1x client software
that supports the EAP authentication type that you want to use.
Windows XP provides native WPA support, other systems
require additional software. Note that Microsoft now has an
802.1x authentication client for Windows 2000 that you can
download from their web site.
SMC2862W-G Utility
18
WEP
Authentication Mode – Choose Open or Shared.
Default Key – Choose the key for encryption.
Key Type – Select 64-bit encryption, 64-bit encryption (ASCII),
128-bit encryption,or 128-bit encryption (ASCII).
Use Passphrase – Check this box to auto-generate keys for
encryption. First, check this box, then enter a string of characters
into the space. Encryption keys will be generated automatically.
When Key Type is set to 128-bit, only one key will be generated. If
Key Type is set to 64-bit, four keys will be generated. Note that
you must use the same passphrase and default key on all the
other clients in your network.
Configuration
19
How to set up WEP:
If you are transmitting sensitive data across wireless channels,
you should enable Wired Equivalent Privacy (WEP) encryption.
WEP provides a basic level of security, preventing unauthorized
access to the network and encrypting data transmitted between
wireless clients and the access point. WEP uses static shared
keys (fixed-length hexadecimal or alphanumeric strings) that are
manually distributed to all clients that want to use the network.
WEP is the security protocol initially specified in the IEEE 802.11
standard for wireless communications. For more robust wireless
security, the SMC2862W-G provides Wi-Fi Protected Access
(WPA) for improved data encryption and user authentication.
Note: Only one key is needed for WEP to function. However, the
IEEE 802.11 standard specifies that there must be four keys
for each device. For security purposes, the key should be
changed on a regular basis. Multiple keys are supported to
allow the user to change keys with minimal disruption of the
network.
To set up the WEP function, take the following steps:
1. Select 64-bit encryption, 64-bit encryption (ASCII), 128-bit
encryption,or 128-bit encryption (ASCII) in the Key Type field.
2. To automatically generate keys, check the Use Passphrase
box, and type in a string of characters in this field.
3. In the Default Key field, select one key as the default key that
you want to use for encryption.
4. Click Apply Change to allow the settings to take effect.
SMC2862W-G Utility
20
Or
1. Select 64-bit encryption, 64-bit encryption (ASCII), 128-bit
encryption,or 128-bit encryption (ASCII) in the Key Type field.
2. In the Default Key field, select one key as the default key that
you want to use for encryption.
3. Manually type in a string of characters in the corresponding
key number field that you selected in step 2.
4. Click Apply Change to allow the settings to take effect.
Note: When setting up WEP without using the Use Passphrase
function, if the Key Type is set to Hex, only Hexadecimal
characters (range: 0~9 and A~F) can be used. When
encryption is set to 64-bit, a maximum of 10 Hex characters
can be entered in the Key field. When encryption is set to
128-bit, a maximum of 26 Hex characters can be used. If the
Key Type is set to ASCII, and encryption is set to 64-bit, then 5
ASCII characters can be used in the Key field. For 128-bit
encryption, 13 ASCII characters can be used.

Advanced
RTS Threshold – This sets the packet size threshold at which a
Request to Send (RTS) signal must be sent to the receiving
station prior to the sending station starting communications.
Devices contending for the wireless medium may not be aware of
each other. The RTS/CTS mechanism can solve this problem.
The larger the threshold, the faster the speed.
Fragment Threshold – Sets the minimum packet size that can
be transmitted from the adapter without being fragmented.
Fragmentation can increase the reliability of transmissions
because it increases the probability of a successful transmission
due to smaller frame size. The larger the threshold, the faster the
speed.
SMC2862W-G Utility
22
Preamble Type – The preamble is used to acquire the incoming
signal and synchronize the receiver. If all the clients in your
service area support the short preamble or can automatically set
the preamble type, then setting the preamble on the access point
to short can boost your throughput. (Options: Short & Long, Long,
Short; Default: Short & Long)
Transmit Power – Move the slider bar up and down to select an
appropriate transmission power. Lower power reduces
interference, higher power gives more range.

NETWORK CONFIGURATION
AND PLANNING
SMC’s EZ Connect g Wireless Solution supports a stand-alone
wireless network configuration, as well as an integrated
configuration with 10/100 Mbps Ethernet LANs.
The SMC2862W-G can be configured as:
•Ad hoc - for small groups that only communicate with each
other, without access points
•Infrastructure - for wireless LANs
Network Topologies
Ad Hoc Wireless LAN
An ad hoc wireless LAN
consists of a group of
computers, each equipped
with one wireless adapter,
connected via radio signals
as an independent wireless
LAN. Computers in a
specific ad hoc wireless
LAN must therefore be
configured to the same
radio channel. An ad hoc
wireless LAN can be used
in a SOHO or temporary environment.

Infrastructure Wireless LANs
The SMC 802.11g access point (SMC2870W) can also provide
wireless workstations with access to a wired LAN. An integrated
wired and wireless LAN is called an infrastructure configuration. A
Basic Service Set (BSS) consists of a group of wireless PC
users, and an access point that is directly connected to the wired
LAN. Each wireless PC in this BSS can talk to any computer in its
wireless group via a radio link, or access other computers or
network resources in the wired LAN infrastructure via the access
point.
The infrastructure configuration not only extends the accessibility
of wireless PCs to the wired LAN, but also extends the effective
wireless transmission range for wireless PCs by passing their
signal through one or more access points.
A wireless infrastructure can be used for access to a central
database, or for connection between mobile workers, as shown in
the following figure.

Setting the Communication Domain
Stationary Wireless PCs
The Basic Service Set (BSS) is the communication domain for
each access point. For wireless PCs that do not need to support
roaming, set the domain identifier (SSID) for the wireless card to
the SSID of the access point to which you want to connect. Check
with your administrator for the SSID of the access point to whick
you are connecting.
Roaming Wireless PCs
A wireless infrastructure can also support roaming for mobile
workers. More than one access point can be configured to create
an Extended Service Set (ESS). By placing the access points so
that a continuous coverage area is created, wireless users within
this ESS can roam freely. All wireless adapters and access points
within a specific ESS must be configured with the same SSID and
to the same radio channel.
You can configure the wireless client to connect to a specific
wireless network or to the first available wireless network.
•If you configure the client to connect to a specific wireless
network, the client establishes a radio connection to the AP in
the specified wireless network that provides the best
communications quality. APs in a different wireless network
are ignored.
•If you configure the client to connect to the first available
wireless network (the SSID = ANY), the client establishes a
radio connection to the AP that provides the best
communications quality. Be aware that if there are multiple
wireless networks, the client could connect to an AP that is not
in the network you want to join.

•In either configuration, the client automatically matches the
radio channel used by the AP.

TROUBLESHOOTING
Check the following troubleshooting items before contacting
SMC technical support.
Adapter Installation Problems
If your computer cannot find the SMC2862W-G adapter or the
driver software does not install correctly, check the following:
•Make sure the adapter is securely seated in the 2.0 USB slot.
Check for any hardware problems, such as physical damage
to the card’s connector.
•Try the card in another USB slot. If this also fails, test your PC
with another wireless adapter that is known to operate
correctly.
•Make sure your PC is using the latest BIOS.
•If there are other network adapters in the PC, they may be
causing conflicts. Remove all other adapters from the PC and
test the wireless adapter separately.
•If it still does not work, go to “Control Panel” and delete the
adapter from your system. Remove the wireless adapter from
your computer. Restart your computer and reinstall the card
and the driver and utility.
Network Connection Problems
35
Network Connection Problems
If the Link LED on the SMC2862W-G adapter does not light, or if
you cannot access any network resources from your computer,
check the following:
•Make sure the correct software driver is installed for your
operating system. If necessary, try reinstalling the driver.
•Make sure the computer and other network devices are
receiving power.
•The access point you want to connect to may be defective. Try
using another access point.
•Make sure the SSID and security settings of the adapter are
set to the same as the access point to which you are
connecting.
If your wireless station cannot communicate with a computer in
the Ethernet LAN when configured for Infrastructure mode, check
the following:
•Make sure the access point that the station is associated with
is powered on.
•If the connection still fails, change the access point and all the
clients within the BSS to another radio channel.
•For a station with roaming disabled, make sure the SSID is the
same as that used by the access point, or the same as that
used by the access points in the extended service set (ESS).
