of channel bonding). The number of available channels authorized for use might be restricted based on your location.

●If the print server is powered on and discovers a wireless network whose SSID (network name) is also hpsetup, it automatically adjusts its channel to match that network.

●If the print server is reconfigured for infrastructure mode, it automatically adjusts its channel to match the access point.

Encryption

Wireless networks use radio signals for network communications, which can be easily monitored by someone eavesdropping on the network. To deter eavesdropping and to help ensure data privacy, encryption of wireless communications should be used.

For HP Jetdirect print servers in their factory-default state, encryption of wireless communications is disabled. However, the print servers support wi-fi protected access (WPA/WPA2) and other popular dynamic encryption protocols.

NOTE: Wireless performance might be reduced when using encryption keys due to the additional processing time required.

Static encryption. WEP (Wired Equivalent Privacy) encryption protocols were developed to provide a basic level of data privacy. WEP protocols use static encryption keys to encrypt and decrypt wireless communications.

NOTE: WEP encryption levels are sometimes called 40-bit, 64-bit, 104-bit, or 128-bit encryption. Forty-bit and 64-bit encryption are really the same, as are 104-bit and 128-bit encryption. When entering WEP keys, the user specifies 40 bits for 64-bit encryption, or 104 bits for 128-bit encryption. An additional 24 initialization vector (IV) bits are automatically added for a total of 64 bits and 128 bits, respectively. In this guide, 40/64-bit and 104/128bit are used to specify these WEP encryption levels.

For basic encryption, static WEP keys are configured on each device on the wireless network. WEP keys are considered static because they remain the same unless manually reconfigured. For example, on a typical infrastructure mode network that uses static WEP encryption, a change to the WEP key on an access point requires a manual change to the WEP key on each wireless device.

HP Jetdirect wireless print servers support configuration of up to four static WEP keys, for either 40/64- bit or 104/128-bit encryption.

Dynamic encryption. For advanced encryption methods, dynamic encryption protocols are used. For dynamic encryption protocols, encryption keys are automatically changed at routine intervals making them difficult to decipher.

Dynamic encryption protocols, such as dynamic WEP and Wi-Fi Protected Access (WPA/WPA2), provide a more secure wireless environment.

When configured for WPA/WPA2–Personal authentication, HP Jetdirect print servers use WPA encryption.
