5. The Fragmentation
Threshold Value,
shown in Figure 9-5 indi-
cates the maximum size
of the transmit frame.
Any data frame larger
than this value will be
fragmented into multiple
frames. Lowering this
value usually means a
lower frame error rate,
but a lower value also
creates more overhead,
which negatively affects
network performance.
The value can only be
entered in increments of
128. Only minor modi-
fications of this value are
recommended. Click
Maximum Listen
Interval to continue or
the OK button to finish
setting the Advanced
Options.
6. The Maximum Listen
Interval, as shown in
Figure 9-6, only applies
when operating in the
Infrastructure mode
while Power Saving is
enabled. The value you
input here will deter-
mine how often the com-
puter “wakes up” from
the power saving mode
to receive any packets
that were sent while it
was “asleep.” The higher
the value entered here,
the longer the time your
computer “sleeps”
between waking up to
check for packets. Click
Network Type to con-
tinue or the OK button
to finish setting the
Advanced Options.
3. The Channel setting,
shown in Figure 9-3,
must be the same for
all wireless points in
the network. Use the
settings, 1-11, to find
the best channel for
your connection. For
further information,
see Chapter 7:
Configuration
Utility. Once your
card is configured,
click the OK button to
finish setting the
Advanced Options.
4. Select either Disabled, 64
bit, or 128 bit as the
value under Encryption,
shown in Figure 9-4.
Wired Equivalent
Privacy (WEP) is an
encryption method used
to protect wireless data
communication. The
Disabled setting pre-
vents the sharing of data
with other computers on
a WEP network. For data
sharing to be enabled,
select either 64 or 128 bit
encryption, depending
on your needs. For fur-
ther information, see
Chapter 7:
Configuration Utility.
Once your card is con-
figured, click OK to fin-
ish setting the Advanced
Options.
