Computer-to-Computer mode. Ad hoc mode is the factory default congured on the HP Jetdirect print

server.

Channel: Select the radio frequency the print server uses to broadcast its availability if it fails to associate

with the specied ad hoc network on any channel. The factory default is channel 11 (2462 MHz). Channel

10 (2457 MHz) is also available. To initially communicate with the print server, the wireless device must be

congured for Ad hoc mode.

In the Authentication and Encryption section, specify the following options:

1. No authentication or encryption: Select this option if device authentication or security is not required to

access the wireless network.

NOTE: The network might continue to use WEP encryption keys for data privacy.

2. WEP (Wired Equivalent Privacy):

●

Authentication: Indicates the authentication mode for the specied WEP settings.

●

WEP-Personal: Select this option if the devices on the wireless network use a shared encryption key

(or a shared password value) for network access and communication. Each device on the network

must use the same key. The HP Jetdirect print server supports IEEE 802.11 WEP keys for encrypted

network communications. If you select this option, specify the following settings to congure the WEP

key:

–

Input key in: Select the format for the WEP key.

–

WEP Key: The WEP key format is programmatically determined and validated by using either

alphanumeric ASCII (8-bit) characters or hexadecimal (4-bit) digits.

–

Index: Select the WEP key index position (1, 2, 3, or 4) the print server uses for encrypted

communications from the list.

●

WEP-Enterprise: Select this option if the network uses WEP with EAP/802.1x authentication. This type

of security uses a central authentication server, such as Remote Authentication Dial-In User Service

(RADIUS), to authenticate users on the network. If you select this option, specify the following

settings to congure the authentication:

–

Enabled protocols: Select one or more of the following server-based authentication protocols:

LEAP: Lightweight Extensible Authentication Protocol. A proprietary protocol from Cisco

Systems that uses passwords for mutual authentication. During mutual authentication, the

client and server authenticate each other.

PEAP (congure certicate using EWS rst): Protected Extensible Authentication Protocol. A

mutual authentication protocol that uses digital certicates for server authentication and uses

passwords for client authentication.

EAP-TLS (congure certicate using EWS rst): EAP using Transport Level Security. A mutual

authentication protocol that uses digital certicates for server authentication and uses

passwords for client authentication. For additional security, the authentication exchanges are

encapsulated in TLS.

–

Encryption strength: Select the minimum encryption strength to use during communications

with the authentication server. For each encryption strength, ciphers are specied to identify the

weakest cipher allowed.

3. WiFi Protected Access (WPA):

●

WPA Version: Select the WPA version.

●

Encryption: Select the encryption method.
