Wireless-N Router
Linksys E1000
Chapter 3: Advanced Configuration
Wireless > Advanced Wireless Settings
The
Advanced Wireless Settings
screen is used to set up
the Router’s advanced wireless functions° These settings
should only be adjusted by an advanced user because
incorrect settings can reduce wireless performance° In
most cases, keep the default settings°

Advanced Wireless
AP Isolation
The AP (Access Point) Isolation feature
isolates all wireless clients and wireless devices on your
network from each other° Wireless devices will be able to
communicate with the Router but not with each other° To
use this option, select
Enabled
° AP Isolation is disabled by
default°
Frame Burst
This option should provide your network
with greater performance, depending on the manufacturer
of your wireless products° To use this option, keep the
default,
Enabled
° Otherwise, select
Disabled
°
Authentication Type
The Authentication Type setting
is available if the Security Mode is RADIUS or WEP° The
default is set to
Auto
, which allows either Open System
or Shared Key authentication to be used° With Open
System authentication, the sender and the recipient do
NOT use a WEP key for authentication° With Shared Key
authentication, the sender and recipient use a WEP key for
authentication° Select
Shared Key
to only use Shared Key
authentication°
Basic Rate
The Basic Rate setting is not actually one
rate of transmission but a series of rates at which the
Router can transmit° (The Basic Rate is not the actual rate
of data transmission° If you want to specify the Router’s
rate of data transmission, configure the Transmission
Rate setting°) The Router will advertise its Basic Rate to
the other wireless devices in your network, so they know
which rates will be used° The Router will also advertise that
it will automatically select the best rate for transmission°
The default setting is
Default
, when the Router can
transmit at all standard wireless rates (1-2 Mbps, 5°5 Mbps,
11 Mbps, 18 Mbps, and 24 Mbps)° Select
1-2 Mbps
for
use with older wireless technology° Select
All
, when the
Router can transmit at all wireless rates°
Transmission Rate
The Transmission setting is available
if the Network Mode is BG-Mixed, Wireless-G Only, or
Wireless-B Only° The rate of data transmission should be
set depending on the speed of your wireless network°
Select from a range of transmission speeds, or keep the
default,
Auto
, to have the Router automatically use the
fastest possible data rate and enable the Auto-Fallback
feature° Auto-Fallback will negotiate the best possible
connection speed between the Router and a wireless
client°
N Transmission Rate
The N Transmission setting is
available if the Network Mode is Mixed or Wireless-N Only°
The rate of data transmission should be set depending
on the speed of your Wireless-N networking° Select from
a range of transmission speeds, or keep the default,
Auto
, to have the Router automatically use the fastest
possible data rate and enable the Auto-Fallback feature°
Auto-Fallback will negotiate the best possible connection
speed between the Router and a wireless client°
CTS
Protection
Mode
The
Router
automatically
uses CTS (Clear-To-Send) Protection Mode when your
Wireless-N and Wireless-G devices are experiencing severe
problems and are not able to transmit to the Router in an
environment with heavy 802°11b traffic° This option boosts
the Router’s ability to catch all Wireless-N and Wireless-G
transmissions but severely decreases performance° To use
this option, keep the default,
Auto
° To disable this option,
select
Disabled
°
Beacon Interval
A beacon is a packet broadcast by the
Router to synchronize the wireless network° The Beacon
Interval value indicates the frequency interval of the
beacon° Enter a value between 20 and 65,535 milliseconds°
The default value is
100
°
DTIM Interval
This value, between 1 and 255, indicates
the interval of the Delivery Traffic Indication Message
(DTIM)° A DTIM field is a countdown field informing
clients of the next window for listening to broadcast
and multicast messages° When the Router has buffered
broadcast or multicast messages for associated clients, it
sends the next DTIM with a DTIM Interval value° Its clients
hear the beacons and awaken to receive the broadcast
and multicast messages° The default value is
1
°
Fragmentation
Threshold
This
value
specifies
the
maximum size for a packet before data is fragmented
into multiple packets° If you experience a high packet
error rate, you may slightly increase the Fragmentation
Threshold° Setting the Fragmentation Threshold too low
may result in poor network performance° Only minor
reduction of the default value is recommended° In most
cases, it should remain at its default value of
2346
