Chapter 4 - System Configuration
Super G – The Atheros proprietary Super G performance enhancements are
supported by the access point. These enhancements provide increased
throughput for connections to Atheros-compatible clients through bursting,
compression, and fast frames (concatenation). (Default: Disabled)
Radio Mode – Selects the operating mode for the 802.11g wireless interface.
(Default: 802.11b+g)
802.11b+g: Both 802.11b and 802.11g clients can communicate with the
access point (up to 54 Mbps).
802.11b only: Both 802.11b and 802.11g clients can communicate with the
access point, but 802.11g clients can only transfer data at 802.11b standard
rates (up to 11 Mbps).
802.11g only: Only 802.11g clients can communicate with the access point (up
to 54 Mbps).
Auto Channel Select – Enables the access point to automatically select an
unoccupied radio channel. (Default: Enabled)
Preamble – Sets the length of the signal preamble that is used at the start of a
data transmission. (Default: Long)
Long: Sets the preamble to long (192 microseconds). Using a long preamble
ensures the access point can support all 802.11b and 802.11g clients.
Short or Long: Sets the preamble according to the capability of clients that are
currently associated. Uses a short preamble (96 microseconds) if all associated
clients can support it, otherwise a long preamble is used. The access point 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.
Beacon Interval – The rate at which beacon signals are transmitted from the
access point. The beacon signals allow wireless clients to maintain contact with
the access point. They may also carry power-management information.
(Range: 20-1000 TUs; Default: 100 TUs)
Data Beacon Rate – The rate at which stations in sleep mode must wake up to
receive broadcast/multicast transmissions.
Known also as the Delivery Traffic Indication Map (DTIM) interval, it indicates how
often the MAC layer forwards broadcast/multicast traffic, which is necessary to
wake up stations that are using Power Save mode. The default value of 2 indicates
