protection method, so 802.11g and 802.11b devices can
co-exist in the same network without speaking at the same
time. Do not disable 54g Protection if there is a possibility
that a 802.11b device may need to use your wireless
network. in Auto Mode. The wireless device uses
RTS/CTS to improve 802.11g performance in mixed
802.11g/802.11b
maximize 802.11g throughput under most conditions.

Preamble Type: preambles are a sequence of binary bits
that help the receivers synchronize and ready for receipt
of a data transmission. Some older wireless systems like
802.11b implementation use shorter preambles. If you are
having difficulty connecting to an older 802.11b device, try
using a short preamble. You can select short preamble
only if the 54g mode is set to 802.11b.

Transmit Power: adjust the transmission range here.
This tool can be helpful for security purposes if you wish to
limit the transmission range.

WMM (Wi-Fi Multimedia): select whether WMM is enable
or disabled. Before you disable WMM, you should
understand that all QoS queues or traffic classes relate to
wireless do not take effects.

WMM No Acknowledgement: select whether ACK in
WMM packet. By default, the Ack Policy for each access
category is set to Disable, meaning that an acknowledge
packet is returned for every packet received. This
provides a more reliable transmission but increases traffic
load, which decreases performance. To disable the
acknowledgement can be useful for Voice, for example,
where speed of transmission is important and packet loss
is tolerable to a certain degree.

WMM APSD: APSD is short for automatic power save
delivery. Selecting enable makes it have very low power
consumption. WMM Power Save is an improvement to the
802.11e
management functionality to WMM.
