Wireless Problems
WEP encryption
not working
when using
Windows Zero
Configuration
(WZC) service
If you are using WEP encryption on the SMC Barricade and
Windows Zero Configuration (WZC) service to configure
the wireless settings on your PC you may experience
problems connecting to the SMC Barricade. This is caused
by a conflict with beacon packet element ID 221 used by the
WPS protocol and Windows Zero Configuration (WZC)
service.
There are four different ways you can easily solve
this problem. Take any one of the following actions:
1. Update WZC.
Please visit Microsoft download center for upgrading the
WZC: Wireless LAN API (KB918997) at
milyID=52a43bab-dc4e-413f-ac71-
158efd1ada50&DisplayLang=en
2. Disable WPS.
Check
Disabled
and click
Apply Changes
on Wi-Fi
Protected Setup (WPS) screen. See “WPS (Wi-Fi
Protected Setup)” on page 4-40 for details.
3. Use WPA/WPA2-PSK.
See “WPA” on page 4-38 for configuring WPA/WPA2-
PSK security.
4. Manually configure profile using WZC.
Disable the security authentication manually.
- Click on

Caution:
DO NOT plug a phone jack connector into any RJ-45 port.
Use only twisted-pair cables with RJ-45 connectors that
conform with FCC standards.
Specifications
Wiring Conventions
For Ethernet connections, a twisted-pair cable must have two pairs of
wires. Each wire pair is identified by two different colors. For example,
one wire might be red and the other, red with white stripes. Also, an RJ-45
connector must be attached to both ends of the cable.

Each wire pair must be attached to the RJ-45 connectors in a specific
orientation. The following figure illustrates how the pins on an Ethernet
RJ-45 connector are numbered. Be sure to hold the connectors in the same
orientation when attaching the wires to the pins.

RJ-45 Port Connection
Use the straight-through CAT-5 Ethernet cable provided in the package to
connect the Barricade to your PC. When connecting to other network
devices such as an Ethernet switch, use the cable type shown in the
following table.

Pin Assignments
With 100BASE-TX/10BASE-T cable, pins 1 and 2 are used for
transmitting data, and pins 3 and 6 for receiving data.
Straight-Through Wiring
If the port on the attached device has internal crossover wiring (MDI-X),
then use straight-through cable.
