Parameter

Description

 

 

 

 

 

number. Value is from 1 to 14; countries/regions might limit the range of

 

approved channels.

 

• (number): Value ranging from 1 to 14, depending on country/region.

 

• None: No channel is in use.

 

• Not Applicable: The WLAN is disabled or this parameter does not apply

 

 

to this network type.

 

 

 

 

 

NOTE: In ad hoc mode, if you are not able to receive or transmit data

 

between your computer and the HP All-in-One, make sure that you are using

 

the same communication channel on your computer and the HP All-in-One.

 

In infrastructure mode, the channel is dictated by the access point.

 

 

 

 

Authentication

Type of authentication in use:

type

• 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.
