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
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)

Configure and manage

background image

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.

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.
