4If you join a wireless network that does not have security, you
should now be connected. To check your connection, open
your Web browser and go to your favorite site.
We highly recommend security. Chapter 2, Setting Security on
page 10 has descriptions of the six security options and setup
instructions.
If you have difficulty accessing the Internet, follow the
suggestions in your browser’s “Page cannot be displayed”
message. You may need to adjust your LAN settings.

Setting Security
We strongly recommend security, although you do not need to
use it to get your wireless connection working.
Important! You must first enable security on the the wireless
access point. You then enable security on the adapter using the
same configuration that you used for the access point. For
example, if the wireless access point is configured for WPA2-
PSK, you must select WPA2-PSK security in the Wireless-G
USB configuration software and enter the same encryption key.
Select one of six ways to configure and implement security for
your wireless network:
•WPA2-PSK (WiFi ® Protected Access 2Pre-Shared Key)
This is the option we recommend, if it is supported by the
access point and the devices in your network. WPA2-PSK
protects your communications with AES (Advanced
Encryption Standard). Some access points permit a “mixed
mode” network composed of both WPA and WPA2 wireless
clients.
WPA2-PSK requires you to enter an encryption key shared
by the access point.
•WPA PSK (WiFi ® Protected Access Pre-Shared Key)
If the devices in your network do not all support WPA2-PSK,
select WPA-PSK. WPA-PSK protects your communications
with TKIP (Temporal Key Integrity Protocol).
10
Wireless-G USB Adapter

This option requires you to enter an encryption key shared
by the access point.
•WEP (Wired Equivalent Privacy)
Both the Open and Shared Authentication modes require
WEP security. The most recent assessments of WEP advise
choosing Open rather than Shared.
If the devices in your network do not support WPA2-PSK or
WPA-PSK, select Open with WEP data encryption.
This method requires you to enter an encryption key. The
keys can be 64, 128 or 256 bits in length.
•WPA2
If you are linking to a corporate network that accesses a
RADIUS (Remote Authentication Dial-In User Service)
authentication server, and if the devices in the network
support WPA2, select WPA2. This option provides security
with AES (Advanced Encryption Standard). AES has a key
size of 128, 192, or 256-bits. In order for eavesdroppers to
decipher a message, they would have to try every possible
key.
•WPA is an option for corporate users who access a RADIUS
(Remote Authentication Dial-In User Service) authentication
server that does not support WPA2. WPA provides security
with TKIP (Temporal Key Integrity Protocol), which
dynamically changes keys as the system is used.
Accessing the Security Screen
1On your desktop, double-click the Zoom Wireless-G USB
icon:

Chapter 2: Setting Security

2The Zoom Wireless-G USB configuration software opens to
display the configuration parameters:
3Make sure that the desired wireless network is displayed in
the Profile and SSID text boxes (the term <Infra>
designates an Infrastructure network) and that the Network
Type is correct.
There are two types of wireless networks: Infrastructure and
Ad Hoc.
•In an Infrastructure network, wireless devices
communicate with each other via a wireless access
point, router, or ADSL modem with built-in wireless
technology.
•In an Ad Hoc network, a group of wireless devices
communicate directly with other “client” devices that are
using wireless adapters. The network does not include a
wireless access point or wireless router.
