Table 4-3 Wireless configuration parameters (continued) Item Description Ad Hoc Network (peer-to-peer) Wireless communication topology in which the wireless devices on a network communicate directly with each other. Access points are not used. Other terms used for ad hoc include independent basic service set (IBSS), and computer-to-computer mode. The factory-default mode configured on the HP Jetdirect print server is ad hoc. To initially communicate with the print server, your wireless computer must be set up for ad hoc. Channel (Ad hoc mode only) Identifies the radio frequency that the print server uses to broadcast its availability if it fails to associate with the specified ad hoc network on any channel. By factory default, channel 11 (2462 MHz) is used. However, channel 10 (2457 MHz) is also available. The factory-default mode configured on the HP Jetdirect print server is ad hoc. To initially communicate with the print server, your wireless computer must be set up for ad hoc. No Security (No encryption or authentication. Open system.) Your wireless network does not require device authentication or security to access the network. However, your network might still use WEP encryption keys for data privacy. WEP (Requires a WEP key.) Each device on your wireless network uses a shared encryption key (a shared password value) for network access and communications. Each device on the network must use the same key. The HP Jetdirect print server supports IEEE 802.11 wired equivalent privacy (WEP) keys for encrypted network communications. If you select WEP encryption, you must configure one or more WEP keys. Provide the following if you select WEP: ● Authentication - Select Open System authentication if your wireless network does not require authentication for network access. (Your network might use WEP encryption keys for data security.) Select Shared Key authentication if your network requires that each device be configured with the same WEP key for network access. Choose Auto to automatically select open or shared. ● WEP Key - The WEP key format is programmatically determined and validated using either alphanumeric ASCII (8-bit) characters or hexadecimal (4-bit) digits. ● Key Index - Specify the WEP key index position (1, 2, 3, 4) that the print server uses for encrypted communications. WPA (WiFi Protected Access) Your network uses WPA. Choose WPA - Personal, which uses a pre-shared key typically generated by a passphrase. Or, select WPA - Enterprise which is commonly used in enterprise-level networks. A dedicated server verifies the identity of a user or device requesting access to the network before granting that access. Select the WPA Version (Auto, WPA, or WPA-2), and then select the Encryption, using Auto, advanced encryption standard (AES), or temporal key integrity protocol (TKIP). WPA - Personal Choose WPA- Personal, which uses a pre-shared key typically generated by a passphrase. Enter the Passphrase to use when generating the pre-shared key for WPA - Personal authentication on your network. A passphrase must be from 8 to 63 ASCII characters in the hexadecimal range 21 through 7E (characters 0-9, a-z, A-Z and numerous special characters including WPA - Enterprise Select WPA - Enterprise security if your network uses WPA with EAP/802.1x authentication. This type of security utilizes a central authentication server, such as RADIUS, to authenticate users on the network. For WPA - Enterprise, the HP Jetdirect 68 Chapter 4 Embedded Web server (V.38.xx) ENWW
