Configuration and Diagnostic Utility

20CHAPTER 4: CONFIGURATION AND DIAGNOSTIC UTILITY

The user-conﬁgurable parameters are:

■Mode - Set the station operation mode to AdHoc for network conﬁgurations that do not have any access points, or to Infrastructure for conﬁgurations with access points ("Ad hoc" is the default setting).

■

SSID - Input an SSID number if the roaming feature is enabled ("101" is the default setting).

Tx Rate - Indicates the communication rates. Select appropriate transmission speed to match your wireless LAN settings ("Fully Automatic" is the default setting).

■WEP - For more secure data transmission, select "Enabled" to use WEP security. The advanced Wired Equivalent Privacy (WEP) is implemented in this card to prevent unauthorized access. However, for normal use it is recommended to retain the factory-set "Disabled" WEP. ("Disabled" is the default setting).

■Channel - If you are setting up an Ad hoc wireless LAN, set the channel number to the same radio channel as that used by the other wireless clients in your group. However, if you are connecting to a network via an access point, then use the same channel as that used by the access point (access point default: 3).
