Preamble: Select Long or Short/Long (auto) Preamble type. Preamble is a

sequence of bits transmitted at 1Mbps that allows the PHY circuitry to reach

steady-state demodulation and synchronization of bit clock and frame start. Two

different preambles and headers are defined: the mandatory supported Long

Preamble and header, which interoperates with the 1 Mbit/s and 2 Mbit/s DSSS

specification (as described in IEEE Std. 802.11), and an optional Short Preamble

and header (as described in IEEE Std. 802.11b). At the receiver, the Preamble and

header are processed to aid in demodulation and delivery of the PSDU. The Short

Preamble and header may be used to minimize overhead and, thus, maximize the

network data throughput. However, the Short Preamble is supported only from the

IEEE 802.11b (High-Rate) standard and not from the original IEEE 802.11. That

means that stations using Short-Preamble cannot communicate with stations

implementing the original version of the protocol.

Support Band: There are two bands available for selection; 11B and 11G.

Advanced

The Advanced settings help you to control the Wireless Adapter to adjust with

wireless devices in certain environment.

Auth. Mode: Eight options are available: Disable, Auto, Open System, Shared Key,

WPA/WPA2, and WPA-PSK/WPA2-PSK. Select Auto, Disable for other

authentication feature. If one of the two options is selected, it is required to select

the Encryption mode from the next dropping list.
