WEP (Wired Equivalent Privacy) Encryption WEP reduces the opportunities for a third party to monitor the information transmitted through wireless LAN network by encrypting the information. To enable the WEP functions, an encryption key or network key must be registered with both communication devices. In this case, only the receivers who have the correct encryption key can decrypt the information. • To use the WEP functions, your communication partner must support the functions. • Your computer supports 128-bit and 64-bit WEP keys. • For enhancement of security, the encryption keys should be periodically changed. • The WEP key is generated from ASCII or hexadecimal entries. Refer to the following for the entries. ASCII format Hexadecimal format Numbers/ 0 to 9, 0 to 9, Letters Characters/ a to z, and A to Z *1 a to f, and A to F *2 5 or 13 characters 10 or 26 digits 5 Digits *1 The uppercase and lowercase letters are distinguished. *2 The uppercase and lowercase letters are not distinguished. Connecting to Internet via an Access Point You can connect your computer to the Internet or a wired network via an access point supporting IEEE 802.11g or IEEE802.11b. You may need to configure your access point for IP address, DNS server address, and gateway address. Refer to the manual of the access point or consult your network administrator if you are not sure. This section describes how to configure your computer for wireless communications. Configuring Wireless LAN Setting You can store the configured settings using Network Setup Utility, which allows you to easily access to one of the stored networks appropriate to the current environment. (For Network Setup Utility, refer to Network Setup Utility later in this chapter.) 5-7
