Network Connection
IP Address
Note: When assigning IP Addresses to the computers on the network, remember to
have the IP address for each computer set on the same subnet mask. If your
Broadband Router use DHCP technology, however, it won’t be necessary for you to
assign Static IP Address for your computer.
1. To configure a dynamic IP address (i.e. if your broadband Router has the DHCP technology), check
the Obtain an IP Address Automatically option.
2. To configure a fixed IP address (if you broadband Router is not DHCP supported, or when you need
to assign a static IP address), check the Use the following IP address option. Then, enter an IP
address into the empty field; for example, enter 192.168.1.1 in the IP address field, and
255.255.255.0 for the Subnet Mask.

System Configuration tab:
Profile Name: User can enter profile name, or use default name defined by
system. The default is PROF# (# 1, #2, #3....).
SSID: The SSID is the unique name shared among all points in your wireless
network. The name must be identical for all devices and points attempting to
connect to the same network. User can use pull-down menu to select from
available APs.
Power Save Mode:
•CAM (Constantly Awake Mode): When this mode is selected, the power
supply will be normally provided even when there is no throughput.
•PSM (Power Saving Mode): When this mode is selected, this device will
stay in power saving mode even when there is high volume of throughput.
Network Type: There are two types, Infrastructure and Ad-hoc modes.
Under Ad-hoc mode user can also choose the preamble type, the available
preamble type includes Auto and Long. In addition to that, the channel field
will be available for setup in Ad-hoc mode.
•The Infrastructure is intended for the connection between wireless network
cards and an Access Point. With the wireless adapter, you can connect
wireless LAN to a wired global network via an Access Point.
•The Ad-hoc lets you set a small wireless workgroup easily and quickly.
Equipped with the wireless adapter, you can share files and printers between
each PC and laptop.
Tx Power: Transmit power, the amount of power used by a radio transceiver to
send the signal out. Select the Tx power percentage from the pull-down list
including Auto, 100%, 75%, 50%, 25%, 10% and Lowest.
Preamble: This function will show up when Ad-hoc network type be selected.
A preamble is a signal used in wireless environment to synchronize the
transmitting timing including Synchronization and Start frame delimiter. Select
from the pull-down menu to change the Preamble type into Auto or Long.
RTS Threshold: User can adjust the RTS threshold number by sliding the bar
or key in the value directly. The default value is 2347. RTS/CTS Threshold is a
mechanism implemented to prevent the “Hidden Node” problem. If the
“Hidden Node” problem is an issue, users have to specify the packet size. The
- 12 -

RTS/CTS mechanism will be activated if the data size exceeds the value you set.
This value should remain at its default setting of 2347. Should you encounter
inconsistent data flow, only minor modifications of this value are
recommended.
Fragment Threshold: User can adjust the Fragment threshold number by
sliding the bar or key in the value directly. The default value is 2346. The
mechanism of Fragmentation Threshold is used to improve the efficiency when
high traffic flows along in the wireless network. If your Wireless LAN Adapter
often transmits large files in wireless network, you can enter new Fragment
Threshold value to split the packet. The value can be set from 256 to 2346.
Authentication and Security tab:
Authentication Type: There are several types of authentication modes
including Open, Shared, Leap, WPA, WPA-PSK, WPA2 and WPA2-PSK.
•Open: If your access point/wireless router is using "Open” authentication,
then the wireless adapter will need to be set to the same authentication type.
•Shared: Shared key is when both the sender and the recipient share a secret
key.
•LEAP: Light Extensible Authentication Protocol. It is an EAP authentication
type used primarily in Cisco Aironet WLANs. It encrypts data transmissions
using dynamically generated WEP keys, and supports mutual authentication
(only with CCX mode enabled.)
•WPA/ WPA-PSK/ WPA2/ WPA2-PSK: WPA or WPA-PSK
authentications offer two encryption methods, TKIP and AES. For
WPA-PSK, select the type of algorithm TKIP or AES and then enter a WPA
Shared Key of 8-64 characters in the WPA Pre-shared Key field.
Encryption Type: For Open and Shared authentication mode, the selection of
encryption type are None and WEP. For WPA, WPA2, WPA-PSK and
WPA2-PSK authentication mode, the encryption type supports both TKIP and
AES.
WPA Pre-shared Key: This is the shared secret between AP and STA. For
WPA-PSK and WPA2-PSK authentication mode, this field must be filled with
character longer than 8 and less than 64 lengths.
WEP Key: Only valid when using WEP encryption algorithm. The key must
match with the AP’s key. There are several formats to enter the keys.
•Hexadecimal (128bits): 26 Hex characters (0~9, a~f).
•ASCII (128bits): 13 ASCII characters.
Show Password: Check this box to show the password you en02tered.
802.1x Setting: When user use radius server to authenticate client certificate for
WPA authentication mode (WPA authentication do not support EAP Method-
- 13 -

MD5-Challenge).
802.1x tab:
EAP Method:
•PEAP: Protect Extensible Authentication Protocol. PEAP transport securely
authentication data by using tunnelling between PEAP clients and an
authentication server. PEAP can authenticate wireless LAN clients using
only server-side certificates, thus simplifying the implementation and
administration of a secure wireless LAN.
•TLS / Smart Card: Transport Layer Security. Provides for certificate-based
and mutual authentication of the client and the network. It relies on
client-side and server-side certificates to perform authentication and can be
used to dynamically generate user-based and session-based WEP keys to
secure subsequent communications between the WLAN client and the
access point.
•TTLS: Tunnelled Transport Layer Security. This security method provides
for certificate-based, mutual authentication of the client and network
through an encrypted channel. Unlike EAP-TLS, EAP-TTLS requires only
server-side certificates.
•EAP-FAST: Flexible Authentication via Secure Tunnelling. It was
developed by Cisco. Instead of using a certificate, mutual authentication is
achieved by means of a PAC (Protected Access Credential) which can be
managed dynamically by the authentication server. The PAC can be
provisioned (distributed one time) to the client either manually or
automatically. Manual provisioning is delivery to the client via disk or a
secured network distribution method. Automatic provisioning is an in-band,
over the air, distribution. For tunnel authentication, only support "Generic
Token Card" authentication now.
•MD5-Challenge: Message Digest Challenge. Challenge is an EAP
authentication type that provides base-level EAP support. It provides for
only one-way authentication - there is no mutual authentication of wireless
client and the network. (Only Open and Shared authentication mode can use
this function.)
- 14 -

Tunnel Authentication:
•Protocol: Tunnel protocol, List information including EAP-MSCHAP v2,
EAP-TLS/ Smart Card, and Generic Token Card.
•Tunnel Identity: Identity for tunnel.
•Tunnel Password: Password for tunnel.
Session Resumption: Reconnect the signal while broken up, to reduce the
packet and improve the transmitting speed. User can click the box to enable or
disable this function.
ID\PASSWORD tab:
ID/ PASSWORD: Identity and password for server.
•Authentication ID / Password: Identity, password and domain name for
server. Only "EAP-FAST" EAP method and "LEAP" authentication can key
in domain name. Domain name can be keyed in blank space.
•Tunnel ID / Password: Identity and Password for server.
