There are two communication mode options:

• Ad hoc: On an ad hoc network, the device is set to ad hoc communication mode and

communicates directly with other wireless devices without the use of a WAP.

All devices on the ad hoc network must:

◦ Be 802.11 compatible

◦ Have ad hoc as the communication mode

◦ Have the same network name (SSID)

◦ Be on the same subnet and same channel

◦ Have the same 802.11 security settings

• Infrastructure (recommended): On an infrastructure network, the device is set to infrastructure

communication mode and communicates with other devices on the network, whether the devices

are wired or wireless, through a WAP. WAPs commonly act as routers or gateways on small

networks.

Security settings

NOTE: For more information on wireless security, visit www.weca.net/opensection/pdf/

whitepaper_wi-fi_security4-29-03.pdf.

• 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; it provides 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.

To set up wireless communication using the device control panel with wireless setup

wizard

The Wireless Setup Wizard provides an easy way to set up and manage a wireless connection to

your device.

NOTE: To use this method, you must have a wireless network set up and running.

1. Set up the device hardware (see the getting started guide or the setup poster that came with

your device).

2. On the device control panel, press the Setup button.

3. Press an arrow button to move to Wireless Menu, and then press OK.

4. Press an arrow button to move to Setup Wizard, and then press OK.

5. Follow the display instructions to complete the setup.
