must be available on all your wireless network devices. The need for a static WEP key depends on the authentication method used. For Open System authentication (the factory default configuration), a static WEP key can be configured but is not required. For Shared Key or EAP-MD5, a static WEP key must be configured, and it must match the active key on the other wireless network devices. The HP Jetdirect print server can store up to four static WEP keys, although only one is active at a time. These WEP keys will remain the same (hence, static) until the network administrator changes them. HP Jetdirect wireless print servers support 40/64-bit and 104/128-bit encryption. When configuring a static 64-bit WEP encryption key, you enter 40 bits of the WEP key. When configuring a static 128-bit WEP encryption key, you enter 104 bits of the WEP key. In both cases, 24 IV (Initialization Vector) bits are automatically added. The HP Jetdirect wireless print server supports WEP key entry using 8-bit alphanumeric ASCII characters (0 through 9, a through z, A through Z) or 4-bit hexadecimal digits (0 through 9, a through f, A through F). Note that alphanumeric ASCII characters are case-sensitive; entering an upper- or lowercase character will result in different WEP key values. If you use hexadecimal characters, you should ensure that the resulting bit values convert to the allowed set of alphanumeric ASCII characters. This will allow you to enter WEP keys on devices that restrict WEP key entry to alphanumeric ASCII characters only. For more information on WEP security, contact the Wireless Ethernet Compatibility Alliance (WECA). HP Jetdirect IEEE 802.11b wireless print servers are WECA Wi-Fi certified products. Wi-Fi, the standard for wireless fidelity, is a trademark of WECA. Dynamic Encryption. Depending on your wireless print server model, the following dynamic encryption protocols are supported: G dynamic WEP G Wi-Fi Protected Access (WPA) When dynamic encryption is used, encryption keys are periodically changed automatically and provide enhanced security.
