ABOUT THE WIRELESS
BARRICADE™GROUTER
Congratulations on your purchase of the Wireless Barricade™ g
Broadband Router. SMC is proud to provide you with a powerful
yet simple communication device for connecting your local area
network (LAN) to the Internet.
Important Information!
This information is addressed to the DSL-Users without
a flat rate contract**.
With your DSL-router you have received a device of high quality,
which allows you fast and easy access to the Internet.
The factory default settings of this router have been done in
a way to provide you with uninterrupted access and use of the
Internet. With this background for cost reasons we recommend
that you enter into a "flat rate" - contract with your DSL-line
provider.
Why should you do that?
Please consider that a router, an entirely independent working
device, does not switch off automatically when shutting off your PC!
You may trigger such an automatic shut-off by setting a so called
"idle-time" (for details consult your manual at PPPoE or PPTP WAN
access configuration). Depending at the set time (1 to 5 min) the
router cuts the DSL-link when idle, indeed. But this still does not
provide for 100% security.
This disconnect only happens if there are no more open requests
received from either the LAN or the WAN side (here this can be
requests from the internet, i.e. initiated through the use of so
called file sharing programs like eMule, eDonkey, etc.) that
keep the router active.

About the Wireless Barricade™ g Router
2
In order to counter such incalculable activity and protect yourself
from higher than expected on-line costs we therefore recommend
again a flat-rate contract for your DSL-connection. The only safe
alternative: Pull the plug! That is to disconnect your router from
the mains.
Please feel free to contact our SMC-hotline if you have further
questions.
** Flat-rate is an offer of your DSL-line provider, which gives you
timely unlimited access to the Internet at a defined (flat-) rate.

Hardware Description
The Wireless Barricade™ can be connected to the Internet or
to a remote site using its RJ-45 WAN port. It can be connected
directly to your PC or to a local area network using any of the
Fast Ethernet LAN ports.
Access speed to the Internet depends on your service type.
Full-rate
ADSL can provide up to 8 Mbps downstream and
6
40 Kbps upstream. G.lite (or splitterless) ADSL provides up
to 1.5
Mbps downstream and 512 Kbps upstream. Cable modems
can provide up to 36 Mbps downstream and 2 Mbps upstream.
I
SDN can provide up to 128 Kbps when using two bearer
channels.
PSTN analog connections can now run up to 56 Kbps.
However, you should note that the actual rate provided by specific
service providers may vary dramatically from these upper limits.
Although access speed to the Internet is determined by the
modem
type connected to the Wireless Barricade™, data
passing between devices connected to your local area
network can run up to 100 Mbps over the Fast Ethernet ports.
The Wireless Barricade™ includes an LED display on the front
panel for system power and port indications that simplifies
installation and network troubleshooting. It also provides four
RJ-45 LAN ports and one RJ-45 WAN port on the rear panel.
•
4 RJ-45 ports for connection to a 10BASE-T/100BASE-TX
Ethernet Local Area Network (LAN). These ports can auto-
negotiate the operating speed to 10/100 Mbps, the mode
to half/full duplex, and the pin signals to MDI/MDI-X
(i.e., allowing these
ports to be connected to any network
device with straight- through
cable). These ports can be
connected directly to a PC or to a server equipped with an
Ethernet network interface card, or to a networking device
such as an Ethernet hub or switch.

Basic Installation Procedure
1. Connect the LAN: Connect the Wireless Barricade™ to your
PC, or to a hub or switch. Run Ethernet cable from one of
the LAN ports on the rear of the Wireless Barricade™ to your
computer’s network adapter or to another network device.
You may also connect the Wireless Barricade™ to your PC
(using a wireless client adapter) via radio signals. Position
both antennas on the back of the Wireless Barricade™ into
the desired positions. For more effective coverage, position
the antennas along different axex. 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).
2. Connect the WAN: Prepare an Ethernet cable for connecting
the
Wireless Barricade™ to a cable/xDSL modem or Ethernet
router.
3. Power on: Connect the power adapter to the Wireless
Barricade™.

Attach to Your Network Using Ethernet Cabling
The four LAN ports on the Wireless Barricade™ auto-negotiate
the connection speed to 10 Mbps Ethernet or 100 Mbps Fast
Ethernet, and the transmission mode to half duplex or full duplex.
Use twisted-pair cable to connect any of the four LAN ports
on the Wireless Barricade™ to an Ethernet adapter on your
PC. Otherwise, you can cascade any of the LAN ports on the
Wireless Barricade™ to an Ethernet hub or switch, and then
connect your PC or other network equipment to the hub or
switch. When inserting an RJ-45 plug, be sure the tab on
the plug clicks into position to ensure that it is properly seated.
Warning: Do not plug a phone jack connector into any RJ-45
port. This may damage the Wireless Barricade™.
Instead, use only twisted-pair cables with RJ-45
connectors that conform with FCC standards.
Figure 3. Making the LAN Connections

Attach to Your Network Using Radio Signals
Install a wireless network adapter in each computer that will be
connected to the Internet or your local network via radio signals.
SMC currently offers several wireless network cards, including
the
SMC2802W and SMC2835W wireless cards.
Rotate both antennas on the back of the Wireless Barricade™
to the desired position. For more effective coverage, position
the antennas around 45 to 90 degrees apart. Try to place the
Wireless Barricade™ in a position that is located in the center
of
your wireless network. Normally, the higher you place the
antenna,
the better the performance. Ensure that the Wireless
Barricade™’s location provides optimal reception throughout
your home or office.
Computers equipped with a wireless adapter can communicate
with each other as an independent wireless LAN by configuring
each computer to the same radio channel. However, the Wireless
Barricade™ can provide access to your wired/wireless LAN or
to the Internet for all wireless workstations. Each wireless PC
in this network infrastructure can talk to any computer in the
wireless group via a radio link, or access other computers or
network resources in the wired LAN infrastructure or over
the Internet via the Wireless Barricade™.
The wireless infrastructure configuration not only extends the
accessibility of wireless PCs to the wired LAN, but also increases
the effective wireless transmission range for wireless PCs by
retransmitting incoming radio signals through the Wireless
Barricade™.
