Network authentication: The device’s factory default

setting is Open, which does not require security for

authorization or encryption. The other possible values

are OpenThenShared, Shared, and WPA-PSK

(Wi-Fi

®

Protected Access Pre-Shared Key).

• WPA increases the level of over-the-air data

protection and access control on existing and future

Wi-Fi networks. It addresses all known weaknesses

of WEP, the original native security mechanism in the

802.11 standard.

• WPA2 is the second generation of WPA security;

providing enterprise and consumer Wi-Fi users with

a high level of assurance that only authorized users

can access their wireless networks.

Data encryption:

• Wired Equivalent Privacy (WEP) provides security by

encrypting data sent over radio waves from one

wireless device to another wireless device. Devices

on a WEP-enabled network use WEP keys to encode

data. If your network uses WEP, you must know the

WEP key(s) it uses.

• WPA uses the Temporal Key Integrity Protocol (TKIP)

for encryption and employs 802.1X authentication

with one of the standard Extensible Authentication

Protocol (EAP) types available today.

• WPA2 provides a new, encryption scheme,

the Advanced Encryption Standard (AES). AES is

defined in counter cipher-block chaining mode

(CCM) and supports the Independent Basic Service

Set (IBSS) to enable security between client

workstations operating in ad hoc mode.

NOTES

• Make sure the device is not connected to the network

using a network cable.

• The sending device must have built-in 802.11

capabilities or an 802.11 wireless card installed.

• HP recommends that the device and the computers

that use the device be on the same subnet.
