FCC - Class B
This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses, and can radiate radio frequency
energy and, if not installed and used in accordance with instructions, may cause
harmful interference to radio communications. However, there is no guarantee that
the interference will not occur in a particular installation. If this equipment does
cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to
correct the interference by one or more of the following measures:
• Reorient the receiving antenna
• Increase the separation between the equipment and receiver
• Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected
• Consult the dealer or an experienced radio/TV technician for help
FCC Caution: To assure continued compliance, (example - use only shielded
interface cables when connecting to computer or peripheral devices) any changes
or modifications not expressly approved by the party responsible for compliance
could void the user's authority to operate this equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the
following two conditions: (1) This device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that
may cause undesired operation.
IMPORTANT NOTE:
FCC Radiation Exposure Statement
FCC Radiation Exposure Statement: This equipment complies with FCC radiation
exposure limits set forth for an uncontrolled environment. This equipment should
be installed and operated with a minimum distance of 20 centimeters (8 inches)
between the radiator and your body. This transmitter must not be co-located or

System Requirements
Before you install the Wireless Ethernet Adapter, be sure you
have met the following requirements:
•An AC power outlet (100~240 V, 50~60 Hz)
•An available RJ-45 (UTP) port on an Ethernet hub or switch
•802.11b compliant wireless Ethernet adapters with TCP/IP
protocols installed
•TCP/IP network protocol installed on each PC that needs to
access the Internet.
•A web browser, such as Microsoft Internet Explorer 5.5 or
above installed on one PC at your site for configuring the
Wireless Ethernet Adapter.

H ARDWARE I NSTALLATION
1. Select the Site – Choose a location for your Wireless Ethernet
Adapter. Usually, the best location is at the center of your
wireless coverage area, if possible within line-of-sight of all
wireless devices.
2. Place the Wireless Ethernet Adapter in a position that gives it
maximum coverage. Normally, the higher you place the
antenna, the better the performance.
3. Position the antennas in the desired positions. For more
effective coverage, position the antennas along different axes.
For example, try positioning the antennas around 45 to 90
degress apart. (The antennas emit signals along the
toroidal plane – and thus provide more effective
coverage when positioned along different axes.)
4. If used in Ethernet Adapter mode, connect the Ethernet cable
to the RJ-45 socket of the device will communicate wirelessly
with an access point.
5. If used in Acces Point, connect the Ethernet cable – The
SMC2671W can be wired to an Ethernet network through an
Ethernet device such as a hub or a switch using category 3, 4,
or 5 UTP Ethernet cable and an RJ-45 connector. (See
“Hardware Description” on page 3 for MDI/MDI-X cabling.)
6. Connect the power cable – Connect the power adapter cable
to the 5 VDC power socket on the rear panel.
Warning: Use only the power adapter supplied with the
SMC2671W.

S YSTEM C ONFIGURATION
The SMC2671W is a Plug-and-Play device. This means that, in
most cases, you will not need to configure it.
The SMC2671W Wireless Ethernet Adapter includes an SNMP
agent that is accessible through an SNMP manager application
(Refer to “Using the Configuration Utility” on page 12.) The latest
version may be downloaded from the SMC web site specified on
the back cover of this manual.
The SMC2671W can be configured by a web browser, which is
Internet Explorer 5.5 or above. Using the web management
interface, you can configure the Wireless Ethernet Adapter and
view statistics to monitor network activity.
Before you attempt to log into the SMC2671W’s web-based
administration, please verify the following.
1. Your browser is configured properly (see below).
2. Disable any firewall or security software that may be running.
3. Confirm that you have a good link LED where your computer
is plugged into the Wireless Ethernet Adapter. If you don’t
have a link light – then try another cable to get a good link.
4. To access the Internet through the Wireless Ethernet Adapter,
you must configure the network settings of the computers on
your LAN to use the same IP subnet as the Wireless Ethernet
Adapter. The default network settings for the Wireless
Ethernet Adapter are:
Gateway IP Address: 192.168.2.1
Subnet Mask: 255.255.255.0
SMC2671W IP Address: 192.168.2.25

Using IPCONFIG
1. Click the “Start” button, click “Run” and type “command.”
2. Press “OK” and a black command prompt will appear.
3. Type “ipconfig” and press enter.
4. Verify that your IP Address is 192.168.2.xxx. If so, you can
now use the SMC EZ Installation Wizard to configure your
SMC2671W. If your IP Address is completely different, please
go to the “Configuring Your IP Address” on page 25.
