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 printer 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 the available settings for the printer, see the network configuration page under Understanding the configuration page.

●Network authentication: The printer'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.
