Finish setup (continued) Parameter Description Authentication type Type of authentication in use: • None: No authentication in use. • Open System (ad hoc and infrastructure): No authentication • Shared Key: WEP key is required. • WPA-PSK (infrastructure only): WPA with Pre-Shared Key. • Not applicable: This parameter does not apply to this network type. Authentication verifies the identity of a user or device before granting access to the network, making it more difficult for unauthorized users to access network resources. This security method is common on wireless networks. A network using Open System authentication does not screen network users based on their identities. Any wireless user can have access from the network. However, such a network might use WEP (Wired Equivalent Privacy) encryption to provide a first level of security against casual eavesdroppers. A network using Shared Key authentication provides increased security by requiring users or devices to identify themselves with a static key (a hexadecimal or alphanumeric string). Every user or device on the network shares the same key. WEP encryption is used along with shared key authentication, using the same key for both authentication and encryption. A network using server-based (WPA-PSK) authentication provides significantly stronger security, and is supported in most wireless access points and wireless routers. The access point or router verifies the identity of a user or device requesting access to the network before granting that access. Several different authentication protocols might be used on an authentication server. Encryption The type of encryption in use on the network: • None: No encryption is in use. • 64-bit WEP: A 5-character or 10-hex-digit WEP key is in use. • 128-bit WEP: A 13-character or 26-hex-digit WEP key is in use. • WPA-AES: Advanced Encryption Standard encryption is in use. This is an encryption algorithm for securing sensitive but unclassified material by US Government agencies. • WPA-TKIP: Temporal Key Integrity Protocol, an advanced encryption protocol, is in use. • Automatic: AES or TKIP is in use. • Not applicable: This parameter does not apply to this network type. WEP aims to provide security by encrypting data over radio waves so that it is protected as it is transmitted from one end point to another. This security method is common on wireless networks. Access Point HW Address The hardware address of the wireless router or access point on the network to which the HP All-in-One is connected: • (MAC address): The unique MAC (Media Access Control) hardware address of the access point. • Not applicable: This parameter does not apply to this network type. Total Packets transmitted The number of packets transmitted by the HP All-in-One without error since it has been turned on. The counter clears after the HP All-in-One is turned off. When a message is transmitted over a packet-switching network, it is broken up into packets. Each packet contains the destination address as well as the data. Connect to a network 27
