Preamble Type: The "Long Preamble" can provide better wireless LAN
compatibility while the "Short Preamble" can provide better wireless
LAN performance.
Broadcast ESSID: If you enabled "Broadcast ESSID", every wireless station
located within the coverage of this access point can discover this
access point easily. If you are building a public wireless network,
enabling this feature is recommended. Disabling "Broadcast ESSID"
can provide better security.
CTS Protection: It is recommended to enable the protection mechanism.
This mechanism can decrease the rate of data collision between
802.11b and 802.11g wireless stations. When the protection mode is
enabled, the throughput of the AP will be a little lower due to a lot of
frame-network that is transmitted.
TX Power: This can be set to a bare minimum or maximum power.
WMM: Wi-Fi MultiMedia if enabled supports QoS for experiencing better
audio, video and voice in applications.
