NOTE: In normal mode, the access point provides a channel bandwidth of 20
MHz, and supports the maximum number of channels permitted by local
regulations (e.g., 13 channels for the United States). In Turbo Mode, the channel
bandwidth is increased to 40 MHz to support the increased data rate. However,
this reduces the number of channels supported (e.g., 5 channels for the United
States).
NOTE: . Check your country's regulations to see if Turbo Mode is allowed.
Super Mode – The Atheros proprietary Super A performance enhancements are
supported by the access point. These enhancements include bursting,
compression, and fast frames. Maximum throughput ranges between 40 to 60
Mbps for connections to Atheros-compatible clients. (Default: Disabled)
Auto Channel Select – Enables the access point to automatically select an
unoccupied radio channel. (Default: Enabled)
NOTE: Check your country's regulations to see if Auto Channel can be disabled.
Radio Channel – The radio channel that the access point uses to
communicate with wireless clients. When multiple access points
are deployed in the same area, set the channel on neighboring
access points at least four channels apart to avoid interference
with each other. For example, in the United States you can
deploy up to four access points in the same area (e.g., channels
36, 56, 149, 165). Also note that the channel for wireless
clients is automatically set to the same as that used by the
access point to which it is linked. (Default: Channel 60 for
normal mode, and channel 42 for Turbo mode)
Antenna ID – Selects the antenna to be used by the access
point; either the included diversity antennas or an optional
external antenna. The optional external antennas that are
certified for use with the access point are listed in the
drop-down menu. Selecting the correct antenna ID ensures that
the access point's radio transmissions are within regulatory
power limits for the country of operation. (Default: 3Com
