7 Configuration The Configuration function helps you to configure the Network and the Security. Network: the setting of the Network mode, the SSID and the Channels.  Network Mode: If you want to connect with an Access Point, please set to “Infrastructure” mode. If you have more stations and just want to set them as local network, please set the mode to “Ad-Hoc” mode.  Network SSID: The SSID differentiates one Wireless LAN group name from another; so all access points and all devices attempting to connect to a specific Wireless LAN group name must use the same SSID. A device will not be permitted to join the BSS unless it can provide the unique SSID. If the SSID parameter is “ANY”, it will detect the strongest signal of the wireless station.  Channel: It shows radio channel numbers that used for Wireless LAN networking. The channel number can be set only under the Ad-Hoc operation mode. In Ad-Hoc mode stations, each station must have the same channel numbers and SSID. In Infrastructure mode, the Wireless USB Adapter will automatically detect the channel number of the Access Point. Security: the setting of the Network Encryption. This function is used to protect wireless communication from eavesdropping. A secondary function of encryption is to prevent unauthorized access to a wireless network, and it can be achieved by using the Encryption function.
8  Encryption Mode: There are two kinds of encryption mode, WEP encryption and WPA-PSK. Click the Enable Encryption to activate the security of the USB Adapter. WEP-Key: WEP (Wired Equivalent Privacy) relies on a secret key that is shared between a mobile station and a base station (Access Point). WEP-Passphrase: the Passphrase in the dialog box helps you to create a group of WEP key in the Key Setting.  Authentication Mode: Open System: with the same WEP key between the stations, the stations don’t need to be authenticated, and this algorithm was set to default. Shared Key: with the same WEP key between the stations in this Authentication algorithm, this type will use packets with encryption by transferring a challenge text which will be acknowledge by both side of the stations. In order to choose which authentication algorithm will be used, you must know which one the station supports this algorithm first. It is recommended to select “Auto” if you are not familiar with the setting.  Default Key (Key 1 ~ Key 4): You can type the key that you want to use from Key#1 to Key #4, and the key that you type will be the encryption between the stations that you connected with.  Key Length, Key Format and WEP Key: If you select 64bit in Hex format, you must type 10 values in the following range (0~F, hexadecimal), or 64bit in ASCII format, you must type 5 values in the following range (0~9, A~Z and a~z Alphanumeric). If you select 128bit in Hex format, you must type 26 values (0~F, hexadecimal), or 128bit in ASCII format, you must type 13 values in the following range (0~9, A~Z and a~z Alphanumeric).
