4.2 Configuration Tab
The Configuration tab shows information of Network Name, Network Type. And
Profiles allows you to save five sets of default settings. After entering the values of
the settings (SSID, Network Type, Channel etc.), set a name in the Profiles field.
29
4.3 WEP Tab
You may enhance the security of your network by enabling the “Encryption” function.
The WEP Required Mode enables you to define the encryption keys that your 802.11g
USB2.0 Adapter should use.
Caution:
If you wish to enable the “Encryption” function, you must enable this function
for all computers of your network, and the WEP key needs to be the same for
all IEEE802.11g stations.
Follow the steps below to set your WEP Required Mode:
1. Select one mode from the drop down menu of WEP required Mode
and set the WEP key. Two modes are available:
A. Manual 64 bits
B. Manual 128 bits
2. Press “Apply” button when finish the WEP setting.
30
a. Select “64 bit” vs “Alphanumeric” and enter 5-digit WEP key.
b. Select “64 bit” vs “Hexadecimal” and enter 10-digit WEP key.
31
c. Select “128 bit” vs “Alphanumeric” and enter 13 digit WEP key.
d. Select “128 bit” vs “Hexadecimal” and enter 26 digit WEP key.
32
d. You may choose “Create Keys with Passphrase”.
33
4.4 Security Tab
Except WEP Tab in previous page, this Tab provides you the enhancement of WEP
security. You may choose the authentication type “MD5-Challenge”, “LEAP”,
“TTLS”, “PEAP”, “TLS/Smartcard” or “WPA-PSK” which would require you to
enter “Username”,“Password” and related data, please contact with MIS administrator
for the settings.
34
a. MD5-Challenge: MD5 is an EAP-Type for authentication. It is analogous to the
PPP CHAP protocol. A challenge string is sent from the Authentication Server to
the Supplicant in the MD5-Challenge Request. The challenge string with the user
password is hashed using MD5 and the hash is returned in the MD5-Challenge
Response. The Authentication Server performs the same hash and compares the result
with that returned by the Supplicant to determine whether the authentication is a
Success or Failure.
35
b. LEAP: LEAP (Lightweight Extensible Authentication Protocol) is a Cisco
proprietary EAP-Type. It is designed to overcome some basic wireless authentication
concerns through Mutual Authentication and the use of dynamic WEP keys.
36
C. TTLS: (Tunneled TLS) is an EAP-Type for authentication that employs a twophase authentication process. In the first phase the Authentication Server is
authenticated to the Supplicant . Using TLS, a secure channel is established through
which the Supplicant can be authenticated to the Authentication Server using legacy
PPP authentication protocols such as PAP, CHAP, and MS-CHAP. TTLS has the
advantage over TLS that it only requires a certificate at the Authentication Server. It
also makes possible forwarding of Supplicant requests to a legacy RADIUS server.
TTLS also supports identity hiding where the Authenticator is only aware of the
anonymous username used to establish the TLS channel during the first phase but not
the individual user authenticated during the second phase.
37
d. PEAP: (Protected Extensible Authentication Protocol) is a two-phase authentication
like TLS. In the first phase the Authentication Server is authenticated to the
Supplicant. Using TLS, a secure channel is established through which any other
EAP-Type can be used to authenticate the Supplicant to the Authentication Server
during the second phase. A certificate is only required at the Authentication Server.
PEAP also supports identity hiding where the Authenticator is only aware of the
anonymous username used to establish the TLS channel during the first phase but not
the individual user authenticated during the second phase.
38
e. TLS/Smartcard: TLS is an EAP-Type for authentication based upon X.509
certificates. Because it requires both the Supplicant and the Authentication Server
to have certificates, it provides explicit Mutual Authentication and is resilient to
man-in-the-middle attacks. After successful authentication a secure TLS link is
established to securely communicate a unique session key from the Authentication
Server to the Authenticator.
39
f. WPA-PSK: Wi-Fi Protected Access (WPA) is a replacement security standard for
WEP. It is a subset of the IEEE 802.11i standard being developed. WPA makes use
of TKIP to deliver security superior to WEP. 802.1X access control is still employed.
The Authentication Server provides the material for creating the keys.
40
4.5 IBSS Tab
When communicating in a peer-to-peer network, you may specify a channel on which
you prefer communications to take place. To specify a channel, click on the channel
to select it, and then click the Apply button.
Note that this is not necessarily the channel on which peer-to-peer communications
will be established. If the IBSS network names (SSID) are the same for nodes in the
peer-to-peer network but they have different preferred channels, a network can still be
established. In this case, if it cannot find a network with the specified network name
on the preferred channel, a station will scan other channels until it finds a peer-to-peer
network with the specified network name on which to communicate.
If you specified Access Point as the network type (in the Configuration Tab),
choosing a channel in this field has no effect until you change the network type to
Peer-to-Peer.

4.6 Domain Tab
A domain refers to a territory in which radio frequency transmissions must conform to
the standards set by a single regulatory agency. For example, in the United States, the
allowed frequencies and channels for wireless data communications are set by the
FCC. Every country is free to set its own standards, although in practice many
countries may use the same standards.
The IEEE 802.11d standard provides a means for a wireless LAN adapter to detect the
domain in which it is located and conform its transmissions to the standards set by the
controlling regulatory agency. Not all PRISM adapters include this mechanism,
however, so the version of the Domain menu displayed by the Configuration Utility
depends on the versions of driver and firmware for your adapter.
-802.11d Support
If you specify None in the 802.11d support field, you must then choose the county in
the Countries/Domains field which corresponds to your location. In this case your
adapter operates according to the standards set by the appropriate regulatory agency.
Note: If you specify Peer-to-Peer as the network type, you must specify None in the
802.11d support field.
42
If you choose Strict in the 802.11d support field, your adapter will only
communicate with Access Points which provide 802.11d support. In this case, the
adapter scans all communications channels for an Access Point which provides
information on the channels, frequencies, and power levels permitted in your location.
Once it finds such an Access Point, the adapter conforms its operations to these
standards. The adapter will not communicate with an Access Point that does not
provide this information, nor will it join or create a peer-to-peer network if Strict
802.11d support is specified in this field.
If you choose Flexible in this field, your adapter can communicate with any Access
Point it finds. In this case, you must also choose the county in the
Countries/Domains field which corresponds to your location. Your adapter then
searches for an Access Point which provides information on the channels, frequencies,
and power levels permitted in your location. If it finds such an Access Point, the
adapter conforms its operations to these standards.
If it does not find an Access Point which provides this information, it then will
establish communications with any Access Point it finds.

5. Network Application
This section consists of the network applications of 802.11g USB 2.0 WLAN Adapter,
including:
A. To Survey the network neighborhood
B. To Share Your Folder with Your Network Member(s)
C. To Share Your Printer with Your Network Member(s)
D. To Access the Shared Folder(s)/File(s) of Your Network Members(s)
E. To Use the Shared Printer(s) of Your Network Member(s)
In fact, the network applications of 802.11g USB 2.0 WLAN Adapter are the same as
they are in a wired network environment. You may refer to the following 3
examples of Surveying the Network Neighborhood, File Sharing and Using the
Shared Folder.
5.1 Surveying the Network Neighborhood
When multiple base stations are up and running in your wireless network, you can use
the procedure described below to display the other computers:
1. Double-click My Network Places to display all stations in your Microsoft
Windows Network Group.
2. To display other workgroups in the network environment, double-click Entire
Network.
3. If there is a second network operating system running in your network
environment (for example a Novell NetWare network), the “Entire Network”
window will also display available servers running under the second network
operating system. If you click on these servers, you may be asked to enter
your user name and password that applies to the other network operating
system. If you cannot find it, verify whether the other wireless computers are:
z Powered up and logged on to the network.
z Configured to operate with identical Microsoft Network settings
concerning:
„ Networking Protocol.
„ Wireless Network Name.
To enable the sharing of Internet access, you should set your WLAN mode as
“Infrastructure” and connect to the access point.
45
5.2 File Sharing
802.11g USB 2.0 WLAN Adapter allows the sharing of files between computers that
are logged onto the same wireless network. If you want to share your folder “My
Documents” with other computers of the wireless network, please highlight the
folder “My Documents” and drag it to Shared Documents folder.
Sharing files in the IEEE802.11g wireless network will be like sharing files on a
wired LAN.
46
5.3 Using the Shared Folder
If you would like to access a shared folder stored in other stations of same network,
please follow the process below:
1.
Double-click the “My Network Places” icon, and then double-click the
computer where the shared folder is located.
2.
Double-click the folder you want to connect to.
3.
Now you may open the needed file(s).
Note! If a password is required, the Windows will prompt a password column to you.
Then you need to enter the password that had been assigned to this shared
folder.
