Method for authenticating to an access point.  If another
method is selected using Wireless LAN Manager, the method selected
here takes precedence.
Available selections:
Auto (Default) - Will attempt Open authentication and then Shared
authentication if Open fails.
Open - Allows any device regardless of its WEP keys to authenticate 
and attempt to associate.
Shared - Requires the client and access point to complete an
authentication sequence using a shared secret key before
associating.

802.11b Preamble
Every data packet is preceded by a sequence of bits, known as the
preamble, that help to identify the beginning of the actual data.
A shorter preamble can increase network efficiency. However, both
the Access Point and the client must be configured the same length.
Available selections:
Long and Short (Default) - Allows the 3Com client card to configure
it's preamble length based on information obtained from the Access
Point.
Long only- Configures the 3Com client card to always use a long
preamble.

ALB Mode*
Autonomous Load Balancing mode maximizes throughput by monitoring 
access point traffic and connecting to the access point with the 
most bandwidth.
Available selections:
Enabled (Default)
Disabled

International Roaming
802.11d roaming automatically detects which wireless channels are
valid based on access point settings.  NOTE: This feature requires
an access point that supports 802.11d International Roaming.
Available selections:
Disabled (Default)

Map Registers
Map Registers are a memory management tool used by the hardware to
transfer data to/from the host computer.  A higher number of map
registers allocates additional system memory for data transfers,
and may help speed the transfer.  Too high of a number will
allocate memory that isn't needed, and reduce the amount of memory
available to the system.  Too low of a number will negatively
impact the speed of the data transfer.
Available selections:
256 (Default)
32 to 512 in increments of 8

Power Save Mode*
Power usage for the 3Com wireless LAN PC card can be minimized by
allowing the device to enter a sleep state during periods of
inactivity.  However, data throughput can be affected due to the
time needed to restore the device to the normal power mode when
data transfers are pending.  The various settings for this mode
control how long the device must be inactive before changing to
the sleep mode.
Available selections:
Maximum (maximum power savings) - Aggressively allow the hardware
to enter the sleep mode.
Normal (Default) - Allow the device to enter sleep state after a
conservative amount of inactivity.
Off (maximum performance)- The device will not be allowed to enter
the sleep state.

Radio On/Off*
This allows the radio to be turned off when the card is not in use,
which results in reduced power consumption by the client card.
Available selections:
On (Default) - Radio power is ON.
Off - Radio power is OFF.

Transmit Power
This allows control of the actual power transmitted through the
card antenna.  Reducing the power can help reduce interference
with other devices.  However, network performance may be reduced
depending on the distance between the Access point and the client
card.
Available selections:
100% (Default)
12.5%
25%
50%
Lowest
