10. The Authentication
setting, shown in Figure
9-23, is Open System
by default. Open
System is another name
for WECA compliant.
WECA Compliant (Default) (also referred to as Open Authentication)
The sender and recipient do NOT share a secret key. Each party generates
its own key-pair and asks the receiver to accept the generated key. Once
accepted, this key is used for a short time only; thereafter a new key is gen-
erated and agreed upon.
Shared Key (Optional)
This is when both the sender and recipient share the same key. They use this
key for an extended length of time. Any eavesdropper that discovers the key
may decipher all packets until the key is changed. As indicated, you should
always use WECA Compliant (Always Use) unless you have some other rea-
son to do so.

8. Under Power Saving
mode (Figure 9-21),
select either Enabled
or Disabled. Disabled
will allow for uninter-
rupted data communi-
cation. Selecting
Enabled allows your
notebook to enter
“sleep” mode and
could interrupt data
communication. For
further information
about Power Save
Mode, see Chapter 7:
Configuration Utility.
9. Select either Disabled,
64 bit, or 128 bit as
the value under
Encryption, as shown
in Figure 9-22). Wired
Equivalent Privacy
(WEP) is an encryp-
tion scheme used to
protect wireless data
communication. The
Disabled setting pre-
vents the sharing of
data with other com-
puters on a WEP net-
work. For data sharing
to be enabled, select
either 64 or 128 bit
encryption.
