RTS
Threshold
Specify
a
Request
to
Send
(
RTS)
Threshold
value
between
0
and
2347.
The
RTS
threshold
indicates
the
number
of
octets
in
an
MPDU,
below
which
an
RTS/CTS
handshake
is
not
performed.
Changing
the
RTS
threshold
can
help
control
traffic
flow
through
the
AP,
especially
one
with
a
lot
of
clients.
If
you
specify
a
low
threshold
value,
RTS
packets
will
be
sent
more
frequently.
This
will
consume
more
bandwidth
and
reduce
the
throughput
of
the
packet.
On
the
other
hand,
sending
more
RTS
packets
can
help
the
network
recover
from
interference
or
collisions
which
might
occur
on
a
busy
network,
or
on
a
network
experiencing
electromagnetic
interference.
Maximum
Stations
Specify
the
maximum
number
of
stations
allowed
to
access
this
AP
at
any
one
time.
You
can
enter
a
value
between
0
and
200.
Transmit
Power
Enter
a
percentage
value
for
the
transmit
power
level
for
this
AP.
The
default
value,
which
is
100%,
can
be
more
cost
‐
efficient
than
a
lower
percentage
since
it
gives
the
AP
a
maximum
broadcast
range
and
reduces
the
number
of
APs
needed.
To
increase
capacity
of
the
network,
place
APs
closer
together
and
reduce
the
value
of
the
transmit
power.
This
helps
reduce
overlap
and
interference
among
APs.
A
lower
transmit
power
setting
can
also
keep
your
network
more
secure
because
weaker
wireless
signals
are
less
likely
to
propagate
outside
of
the
physical
location
of
your
network.
Fixed
Multicast
Rate
Select
the
multicast
traffic
transmission
rate
you
want
the
AP
to
support.
Legacy
Rate
Sets
Check
the
transmission
rate
sets
you
want
the
AP
to
support
and
the
basic
rate
sets
you
want
the
AP
to
advertise:
•
Rates
are
expressed
in
megabits
per
second.
•
Supported
Rate
Sets
indicate
rates
that
the
AP
supports.
You
can
check
multiple
rates
(click
a
check
box
to
select
or
de
‐
select
a
rate).
The
AP
will
automatically
choose
the
most
efficient
rate
based
on
factors
like
error
rates
and
distance
of
client
stations
from
the
AP.
•
Basic
Rate
Sets
indicate
rates
that
the
AP
will
advertise
to
the
network
for
the
purposes
of
setting
up
communication
with
other
APs
and
client
stations
on
the
network.
It
is
generally
more
efficient
to
have
an
AP
broadcast
a
subset
of
its
supported
rate
sets.
MCS
(Data
Rate)
Settings
(802.11n
modes
only)
This
field
shows
the
Modulation
and
Coding
Scheme
(MCS)
index
values
supported
by
the
radio.
Each
index
can
be
enabled
and
disabled
independently.
Broadcast/
Multicast
Rate
Limiting
Enabling
multicast
and
broadcast
rate
limiting
can
improve
overall
network
performance
by
limiting
the
number
of
packets
transmitted
across
the
network.
By
default
the
Multicast/Broadcast
Rate
Limiting
option
is
disabled.
Until
you
enable
Multicast/Broadcast
Rate
Limiting
,
the
following
fields
will
be
disabled.
Broadcast/
Multicast
Rate
Limit
Enter
the
rate
limit
you
want
to
set
for
multicast
and
broadcast
traffic.
The
limit
should
be
greater
than
1,
but
less
than
50
packets
per
second.
Any
traffic
that
falls
below
this
rate
limit
will
always
conform
and
be
transmitted
to
the
appropriate
destination.
The
default
and
maximum
rate
limit
setting
is
50
packets
per
second.
Broadcast/
Multicast
Rate
Limit
Burst
Setting
a
rate
limit
burst
determines
how
much
traffic
bursts
can
be
before
all
traffic
exceeds
the
rate
limit.
This
burst
limit
allows
intermittent
bursts
of
traffic
on
a
network
above
the
set
rate
limit.
The
default
and
maximum
rate
limit
burst
setting
is
75
packets
per
second.
