If LEAP is enabled on your client adapter, Open is the only available option.
The Shared Key option is available only if the client adapter has been assigned a WEP key
and WEP is enabled. Refer to the Chapter 4, "Security Features" for instructions on setting
a WEP key and enabling WEP.
Specifies the rate at which you want your client adapter to transmit or
receive packets to or from access points (in infrastructure mode) or other
clients (in ad hoc mode).
The data rate must be auto or the same as the wireless device with which you
wish to communicate.

Description
Allows your client adapter, regardless of its WEP
settings, to authenticate and attempt to
communicate with an access point.
Allows your client adapter to communicate only
with access points that have the same WEP keys.
The access point sends a known unencrypted
"challenge packet" to the client adapter, which
encrypts the packet and sends it back to the access
point. The access point attempts to decrypt the
encrypted packet and sends an authentication
response packet indicating the success or failure of
the decryption back to the client adapter.
Description
Uses the 11-Mbps data rate when possible but drops
to lower rates when necessary.
Offers the greatest range but the lowest throughput.
Offers less range but greater throughput than the 1
Mbps Only option.
Offers less range but greater throughput than the 2
Mbps Only option.
Offers the greatest throughput but the lowest range.
