NOTE:
If you have client devices that do not
support Wi-Fi Protected Setup, note the wireless

client devices.
Wireless > Wireless Security
The
Wireless Security
screen configures the security of
your wireless network. There are six wireless security
mode options supported by the Router: WPA Personal,
WPA Enterprise, WPA2 Personal, WPA2 Enterprise, RADIUS,
and WEP. (WPA stands for Wi-Fi Protected Access, which
is a security standard stronger than WEP encryption. WEP
stands for Wired Equivalent Privacy, while RADIUS stands
for Remote Authentication Dial-In User Service.) These
six are briefly discussed here. For detailed instructions
on configuring wireless security for the Router, refer to
Chapter 2: Wireless Security Checklist

the Router’s advanced wireless functions. These settings
should only be adjusted by an expert administrator as
incorrect settings can reduce wireless performance.
Wireless > Advanced Wireless Settings
Advanced Wireless
AP Isolation
This 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 function, select
Enabled
. AP
Isolation is disabled by default.
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 24Mbps). Select
1-2Mbps
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
Enter a value between 1 and 65,535
milliseconds. The Beacon Interval value indicates the
Page 20 / 65
Chapter 3
Advanced Configuration
16
Wireless-N Broadband Router with Storage Link
frequency interval of the beacon. A beacon is a packet
broadcast by the Router to synchronize the wireless
network. The default is
100
milliseconds.
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
.
RTS Threshold
Should you encounter inconsistent data
flow, only minor reduction of the default value,
2347
, is
recommended. If a network packet is smaller than the
preset RTS threshold size, the RTS/CTS mechanism will
not be enabled. The Router sends Request to Send (RTS)
frames to a particular receiving station and negotiates
the sending of a data frame. After receiving an RTS, the
wireless station responds with a Clear to Send (CTS) frame
to acknowledge the right to begin transmission. The RTS
Threshold value should remain at its default value of
2347
.
