Country: The country where this wireless device resides. The channel settings are restricted
n
to the legal set for the selected country.
Channel: The frequency channel that the wireless radio will use. Select Auto-Scan to have the
n
device scan all frequencies until it finds one with an available access point or wireless network
it can join.
Transmit Power: The transmit power level in dBm.
n
Enable Short Preamble: Enables transmission of wireless frames using short preambles. If
n
Short Preamble is supported in the wireless network, enabling it can boost overall throughput.
Wi-Fi security settings
Use the Wi-Fi Security Settings page to specify the wireless security settings that the wireless
network uses. Multiple security and authentication modes may be chosen depending on the
configuration of the access point or wireless network. The wireless device will automatically select
and determine the authentication and encryption methods to use while associating to the wireless
network. If the wireless network does not use security and uses an Open Network architecture, these
settings do not need to be modified.
Note that WPA settings require that the device communicate to Access Points and is not valid when
the Connection Method is set to Connect to wireless systems using peer-to-peer (ad-hoc). Also,
WPA pre-shared key (WPA-PSK) security is only valid when you use a specific Network Name or SSID.
Network Authentication: The authentication method or methods used for wireless
n
communications.
Use any available authentication method: Enables all of the methods. The capabilities of
l
the wireless network determines the actual method used.
Use the following selected method(s): Selects one or more authentication methods for
l
wireless communications.
Open System: Uses IEEE 802.11 open system authentication to establish a connection.
l
Shared Key: Uses IEEE 802.11 shared key authentication to establish a connection. At
l
least one WEP key must be specified in order to use shared key authentication.
WEP with 802.1x authentication: Uses IEEE 802.1x authentication (EAP) to establish a
l
connection with an authentication server or access point. Wired Equivalent Privacy (WEP)
keys are dynamically generated to encrypt data over the wireless network.
WPA with pre-shared key (WPA-PSK): Uses the Wi-Fi Protected Access (WPA) protocol
l
with a pre-shared key (PSK). The PSK is calculated using a passphrase and the network
SSID.
WPA with 802.1x authentication: Uses the WPA protocol and IEEE 802.1x authentication
l
(EAP) to establish a connection with an authentication server or access point. Encryption
keys are dynamically generated to encrypt data over the wireless link.
Cisco LEAP: Uses Lightweight Extensible Authentication Protocol (LEAP) to establish a
l
connection with an authentication server or access point. Wired Equivalent Privacy (WEP)
keys are dynamically generated to encrypt data over the wireless link. A user name and
password must be specified to use LEAP.
