Wireless NIC Configuration Using The Control Panel
29
• Channel
This is the frequency used for wireless communication. The
2.4GHz band spectrum is divided into different channels (1-15). It is
set to "Default" so that the NIC can detect the correct channel to
communicate with the Access Point in infrastructure mode. If the
operation mode is "Ad Hoc" and the channel is known, the user can
set the corresponding channel in this menu.
NOTE: This parameter is not applicable for 802.11g/b.
• Ant. Diversity
This is used to select the antenna for communication. It is
recommended to set to "Primary" for the NIC to detect for optimal
communication. It can also be set to "Diverse" or "Auxiliary".
• Preamble
This is the preamble used in the wireless packets. It is
recommended to set to "Default" so that the NIC can detect the
correct preamble. The preamble is approximately 8 bytes of the
packet header generated by the AP is and attached to the packet
prior to transmission. The preamble length is transmission data rate
dependent. The "short" preamble is 50% shorter than the "long"
preamble. Transmit power is 0–100%. It must match the Access
Point's preamble configuration.
NOTE: This parameter is not applicable for 802.11g/b.
• Power Mgmt
This option allows you to set power-save mode and sleep time.
A value specifying the sleep time in milliseconds will be provided.
If set to zero, power-save mode will be disabled. It is recommended
not to change this setting.
• Transmit Power
This option allows you to specify the power level used by the
wireless card to send network packets to the access point. Transmit
power is specified as a percentage of full pwer (0 – 100%).
• Internat. Mode
When enabled, the Wireless option adapts to international
frequency requirements in Europe.
