ENCRYPTION
Under the drop-down box, you can choose to have WEP encryption Disabled,
64-Bit, or 128-Bit. Wired Equivalent Privacy (WEP) is an encryption scheme
used to protect wireless data communication. The Disabled setting prevents the
sharing of data with other computers on the WEP network. When selecting
Manual Entry for the WEP Key Entry, enter the hexadecimal number set by
other wireless WEP settings; these settings have to be identical to the WEP
encryption in order to network to your Wireless USB Network Adapter.
In order to find the WEP encryption set by other wireless products in your net-
work, such as the WAP11, you may run the USB utility or SNMP configura-
tion program to check the encryption tab for the correct key entries. If you are
using other access points, please check their respective user guides for more
information on WEP encryption configuration.
In order to enable WEP encryption, hexadecimal values must be entered.

Instant Wireless TM Series Network PC Card
In order to enable 128-bit WEP encryption, choose 128 Bits in the drop-down
box. In the drop-down box near the bottom right-hand corner of the page,
choose which Default Tx Key will be used for the encryption. By default, Key
1 will be used. In the box corresponding to the default you chose, enter a hexa-
decimal number* that the encryption algorithm will be based on. Click Apply
Changes when you are done.

ADVANCED
The Advanced tab allows you to set the Fragmentation Threshold, the
RTS/CTS Threshold, and the Preamble Type. The Fragmentation
Threshold Value indicates how much of the network resources is devoted to
recovering packet errors. The value should remain at its default setting of
2,436. If you experience high packet error rates, you can decrease this value but
it will likely decrease overall network performance. Only minor modifications
of this value are recommended.
The RTS Threshold
Value should remain
at its default setting
of 2,437. A pream-
ble is a signal used
to synchronize the
transmission timing
between two or more
systems. A series of
transmission pulses
is sent before the
data to indicate that
"someone is about
transmit data." This
ensures that systems
receiving the infor-
mation correctly
when the data trans-
mission starts.
Note: In most cases, you will not need to change these settings.
