Understanding Wireless Security

Understanding

Wireless Security

Anyone within range of your wireless network is a potential
security risk. Without wireless security options configured on your
network, a person outside of your physical location, but within
your wireless range may be able to access the network and any
data that is being transmitted over it. SMC Networks’ wireless
devices support the wireless security standard called Wired
Equivalent Privacy (WEP) to prevent unauthorized users from
accessing your network over a wir eless connection. This security
feature uses a secure network key, called a WEP key. The WEP
key encrypts wireless data so that it is only readable by other
computers that have the matching WEP key. The WEP key is
stored on each wireless device, so that data can be encrypted
and decrypted as it is transmitted over the network.

While the Institute of Electrical & Electronics Engineers (IEEE)

802.11i standard is being finalized, an interim solution called

Wi-Fi Protected Access (WPA) has been introduced. The EZ
Connect™ g Wireless Ethernet Bridge is the first device of its
kind to support this new wireless security specification. WPA
defines a set of interoperable se curity enhancements tha t gr eatly
improve upon the level of data encryption and au th e ntic at i on or
access control for e xisting and future wireless LAN systems . WPA
includes Extensible Authentication Protocol (EAP), Temporal Ke y
Integrity Protocol (TKIP) and 802.1X for authentication and
dynamic key exchange. In the WPA-enabled network, the client
first associates with the Access Point. The Access P oint does not
allow network access until the user can be successfully
authenticated. If the client shows the correct credentials to the

8

Understanding Wireless Security

Remote Authentication Dial-In User Service (RADIUS) server, the
client is allowed to join the network. If not, the client stays b loc ked
from joining the LAN. Once the client joins the network, the
authentication server distributes a TKIP encryption key to both
the client and the Access Point. The client can then begin
communicating on the network and maintain the connection,
encrypting data back and forth with the Access Point. Note that
for environments without a Remote A uthentication Dial-In User
Service (RADIUS) infrastructure, WPA supports the use of a
pre-shared key (PSK). WPA-PSK specifies that encryption keys
be dynamically changed (called rekeying) and authenticated
between devices after a specified period of time, or after a
specified number of packets has been transferred.

If you are transferring private information over this wireless
connection, it is recommended to enable WEP or WPA for your
EZ Connect™ g Wireless Ethernet Bridge.

Hardware Installation

Hardware Installation

1. Select the Site – Choose a location f or your Wireless Ethernet

Bridge. 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 Bridge 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

effectiv e cov erage, positio n the antennas along diff erent ax es.
For example, try positioning the antennas arou nd 45 to 90
degrees apart. (The antennas emit signals along the toroidal
plane – and thus provide more effective coverage when
positioned along different axes.)

4. If used in Wireless Bridge mode, connect the Ethernet cable

to the RJ-45 socket of the device will communicate wirelessly
with an access point.

5. If used in Access Point mode, connect the Ethernet cable –

The SMC2870W 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.

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 SMC2870W.

7. Check the LED’s on the front of the unit to make sure the

adapter is turned on properly and the status is okay.
