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 wireless
access point, such as a wireless router or Apple AirPort Base Station.
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 wireless access point,
such as a router or Apple AirPort Base Station.

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

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.
