Understand 802.11 wireless network settings

Network name (SSID)
By default, the device looks for the wireless network name or SSID named "hpsetup." Your network
may have a different SSID.
Communication mode

Network setup (some models only)

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

Security settings

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

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
