Network configuration consists of specifying values for association and authentication, as explained in the following sections. Association Tab Association refers to the ability to join a network, either infrastructure or adhoc. The most basic requirement for associating with a network is specifying the correct network name, or Service Set Identifier (SSID), for the network. Networks may also require authentication and encryption for access. Authentication is the method used by the network to determine whether you are authorized to join the network. Encryption is the method used to mask data transmitted over the network. If this is the case for the network you are configuring, you must enter the authentication and encryption types for your network in the Wireless Network Key section of this menu. To choose a value for these fields, click the down arrow to the right of the appropriate field and highlight one of the values that appear in the drop-down list. file://C:\Documents and Settings\Mark\My Documents\Reports to review\J59313\submittal items\... 4/27/2005 Configuring a Wireless Network: Dell Wireless USB Adapter User's Guide Page 4 of 13 Authentication There are four types of authentication:

Open authentication

Shared authentication

WPA authentication

WPA-PSK authentication Open, Shared, and WPA authentication require no further configuration. To use WPA-PSK authentication, you must click the Properties button next to this field and enter a shared secret key. You may type either between 8 and 63 alphanumeric characters or exactly 64 hexadecimal characters. Encryption Open and Shared authentication can use WEP (Wired Equivalent Privacy) encryption to mask transmitted data. When you specify that WEP is enabled for the network, you must enter the WEP encryption keys by clicking the Properties button to the right of the Encryption Type field. When you click this button, the Configuration Utility selects Enter Manual Keys, and allows you to enter keys as either alphanumeric or hexadecimal characters. To enter a key, click in the field for any of the file://C:\Documents and Settings\Mark\My Documents\Reports to review\J59313\submittal items\... 4/27/2005 Configuring a Wireless Network: Dell Wireless USB Adapter User's Guide Page 5 of 13 four WEP keys and begin typing. For 64-bit encryption, you must type exactly 5 alphanumeric or 10 hexadecimal characters in these key fields; for 128-bit encryption, you must type exactly 13 alphanumeric or 26 hexadecimal characters. You then click the OK button to create your encryption keys. After you click the OK button, the Configuration Utility uses asterisks to mask your keys. The Global (default) key field lets you specify which of the four encryption keys you use to transmit data on your wireless LAN. You can change the default key by clicking on the up or down arrow at the right of this field until the number of the key you want to use appears. As long as the Access Point or computer with which you are communicating has the same key in the same position, you can use any of the keys as the default. To create encryption keys using a passphrase, click the radio button next to Enter Passphrase and type a character string in the Passphrase field. As with creating keys manually, you must type exactly 5 alphanumeric or 10 hexadecimal characters for 64-bit encryption, or exactly 13 alphanumeric or 26 hexadecimal characters for 128-bit encryption. After you click the OK button, the Configuration Utility generates 4 WEP keys and uses asterisks to mask your keys. For WPA and WPA-PSK authentication, you can specify either TKIP or AES encryption. Neither of these encryption methods requires configuration. Two fields appear at the bottom of the Association menu. If you check the first field (by clicking in the box to the left of the field), your computer can associate with Access Points that do not support encryption, provided that the network name used by the AP matches the Network name specified in this menu. If the network that you are configuring is an ad-hoc network, the second field at the bottom of the Association menu is checked. If you are adding an adhoc network, click the check box next to this field. When this field is checked, you specify the channel used in the ad-hoc network by clicking the down arrow to the right of the Ad-hoc Channel field and highlighting the appropriate channel.
