◆ Preamble Type — Sets the length of the signal preamble that is used
at the start of a data transmission. (Default: Long)
■
Long Preamble: Sets the preamble to long (192 microseconds).
Using a long preamble ensures the wireless interface can support all
802.11b and 802.11g clients.
■
Short Preamble: Sets the preamble according to the capability of
clients that are currently asscociated. Uses a short preamble (96
microseconds) if all associated clients can support it, otherwise a
long preamble is used. The wireless interface can increase data
throughput when using a short preamble, but will only use a short
preamble if it determines that all associated clients support it.
◆ Broadcast SSID — Enables/disables the wireless interface to
broadcast an SSID (service set identifier) to uniquely identify it on the
network.
◆ Apply Changes — Applies the specified changes.
