Common

Common allows you to configure the basic wireless parameters:
The following fields are available: Network Name (default: speedtouch) Input an SSID string for the wireless network to which you want to connect. This should be set to the same value as the SSID of the access point or wireless router to which you are connected. Set this value to ANY to allow connection to any access point. This assumes that the access points are broadcasting the SSID. If not, then set the SSID to the value configured on the Access Point. Operating Mode Set the operation mode to: 802.11 ad hoc To create a wireless network without access point. Infrastructure For connections with an access point. Transmit Rate Indicates the data transmission rate. Select an appropriate transmission speed. Channel If you are setting up an ad hoc wireless LAN, set the channel to the same radio channel as that used by the other wireless clients in your group. However, if you are connecting to a network via an access point, then the channel is automatically set by the access point.

Security

The Security ON/Security OFF button indicates whether the security function has been enabled or disabled:
By default wireless security is disabled. Click Security OFF to enable the security function (the button changes to Security ON):
The following fields are available: Authentication Type WEP (Wired Equivalent Privacy) and WPA (Wi-Fi Protected Access) are implemented in the SpeedTouch121g to prevent unauthorized access. Authentication Mode This drop-down list box allows you to choose between following modes: Open: All wireless clients using a correct SSID and WEP key are able to authenticate. The WEP key is only used to authenticate. Shared: Only wireless clients using a correct SSID and WEP key are able to authenticate. The WEP key is used to authenticate and to encrypt/decrypt data. Please consult the user documentation of your Access Point to find out which authentication type to use. In most cases, the Open System type will be used. Key Length Set the Key Length to 128-bit or 64-bit.
Use Passphrase Select the Use Passphrase option to automatically generate key strings for encryption. Both SpeedTouch121g and the access point must use Passphrase. Key Type Select ASCII or Hex. Default Key Choose the key for encryption.

How to set up WEP

WEP provides a basic level of security, preventing unauthorized access to the network and encrypting data transmitted between wireless clients (and the access point). WEP uses static shared keys (fixed-length hexadecimal or alphanumeric strings) that are manually distributed among all clients that want to use the network.
To use the WEP function, take the following steps:
Select WEP from the Authentication Type drop-down menu. Select 128-bit or 64-bit in the Key Length field. In the Key Type field, select ASCII or Hex. In the Default Key field, select one key as the default key that you want to use for encryption. Manually type in a string of characters in the corresponding Key # (Key 1~Key 4) field that you selected in step. Click Apply changes to allow the settings to take effect.

How to set up WPA

Wi-Fi Protected Access is an interoperable security enhancement that strongly increases the level of data protection and access control for existing and future wireless LAN systems. It is derived from and will be forward-compatible with the upcoming IEEE 802.11i standard. WPA employs a combination of several technologies to provide an enhanced security solution for 802.11 wireless networks, including TKIP (Temporal Key Integrity Protocol) for data protection and 802.1x for authenticated key management. WPA provides a simple operating mode that uses just a pre-shared password for network access. The Pre-Shared Key mode uses a common password for user authentication that is manually entered on the access point and all wireless clients on the network. Manual Pre-Shared Key supports up to 64 characters.

To use the WPA function, take the following steps:
Select WPA-PSK from the Authentication Type drop-down menu. Type in the Shared Secret Key (PSK). Click Apply changes to allow the settings to take effect.
If there is no authentication server on your network, you can issue the Pre-Shared Key to your SpeedTouch121g. Be sure to use the same key for the wireless access point and your SpeedTouch121g.
