(DTIM).
A
DTIM
is
a
countdown
that
informs
clients
about
the
next
window
for
listening
to
broadcast
and
multicast
messages.
The
default
value
is
1.
Note:
The
DTIM
is
a
multiple
of
the
Beacon
(TIM),
so
if
the
DTIM
is
set
to
3,
a
DTIM
message
is
sent
with
every
third
Beacon.
Preamble
Type
Tells
the
receiver
that
data
is
on
the
way.
The
preamble
allows
the
receiver
to
acquire
the
wireless
signal
and
synchronize
itself
with
the
transmitter.
Select
Long
Preamble
or
Short
Preamble
.
Long
Preamble
can
provide
better
wireless
LAN
compatibility
with
legacy
devices,
while
Short
Preamble
can
provide
better
WLAN
performance.
Tx
Power
Lets
you
increase
or
decrease
transmit
power.
Higher
transmit
power
may
prevent
connections
to
the
network,
while
the
lower
transmit
power
can
prevent
clients
from
connecting
to
the
device.
Distance
Specify
the
distance
between
Access
Points
and
clients.
Longer
distances
may
drop
high
‐
speed
connections.
Layer
2
Isolation
Enable
or
disable
Layer
2
Isolation.
Layer
2
isolation
prevents
communication
and
data
sharing
between
wireless
stations
associated
with
different
Access
Points.

Fragment
Threshold
Specify
the
maximum
packet
size
during
transmission.
If
a
large
number
of
clients
are
accessing
the
WLAN,
specify
a
small
value
to
avoid
collisions.
RTS
Threshold
RTS
threshold
is
a
trigger
to
engage
the
exchange
of
RTS
and
CTS
messages
between
the
Access
Point
and
client.
The
trigger
is
a
type
of
“handshaking”
approach
that
provides
an
additional
layer
of
control
over
the
use
of
the
shared
medium
by
indicating
the
amount
of
time
a
wireless
device,
attempting
to
send,
will
wait
for
a
recipient
to
acknowledge
that
it
is
ready.
If
the
packet
size
is
smaller
than
the
RTS
threshold,
the
wireless
router
will
not
use
the
RTS/CTS
mechanism
to
send
