HP Officejet Pro K550 Printer - Manual (Page 94)

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.

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.
