Parameter Description
Profile Name Define a recognizable profile name for you to identify the different
networks.
Network Name (SSID) The SSID (up to 32 printable ASCII characters) is the unique
name identified in a WLAN. The ID prevents the unintentional
merging of two co-located WLANs.
You may specify a SSID for the adapter and then only the device
with the same SSID can interconnect to the adapter.
This is a computer-to-computer (ad
hoc) network; wireless access
points are not used.
There are two kinds of network type described as follows.
Infrastructure – This operation mode requires the presence of an
802.11 Access Point.All communication is done via the Access
Point or Router.
Ad Hoc – Connect to another wireless adapters in the Wireless
LAN network without through anAccess Point or Router.
If this item is selected, the adapter will work inAd Hoc mode.

15
Parameter Description
Channel This setting is only available for Ad Hoc mode. Select the number
of the radio channel used for the networking. The channel setting
should be the same with the network you are connecting to.
Network Authentication This setting has to be consistent with the wireless networks that
the adapter intends to connect.
Open System – No authentication is needed among the wireless
network.
Shared Key – Only wireless stations using a shared key (WEP
Key identified) are allowed to connecting each other.
WPA-PSK –It is a special mode designed for home and small
business users who do not have access to network authentication
servers. In this mode, known as Pre-Shared Key, the user
manually enters the starting password in their access point or
gateway, as well as in each wireless stations in the network. WPA
takes over automatically from that point, keeping unauthorized
users that don’t have the matching password from joining the
network, while encrypting the data traveling between authorized
devices. The encryption method supported by the adapter is TKIP.
Data Encryption Disabled – Disable the WEP Data Encryption.
WEP – Enable the WEP Data Encryption. When the item is
selected, you have to continue setting the WEP Encryption keys.
TKIP – TKIP (Temporal Key Integrity Protocol) changes the
temporal key every 10,000 packets (a packet is a kind of message
transmitted over a network.) This insures much greater security
than the standard WEP security.
Note: All devices in the network should use the same encryption
method to ensure the communication.
ASCII WEP Key can be ASCII format. Alphanumeric values or signs are
allowed to be the WEP key. It is more recognizable for user.
Passphrase It is a text string with a maximum of 32 alphanumeric characters,
for example: “Test“. The WEP Key is based upon the Passphrase
determined by you. This passphrase may not work with other
vendors’ products due to possible incompatibility with other
