Method #3
Use this method if your client device asks for the Router’s
PIN number.
Enter the PIN number listed on this screen. (It is also
1.
listed on the label on the bottom of the Router.)
After the client device has been configured, click the
2.
OK
button. Then refer back to your client device or its
documentation for further instructions.
The Wi-Fi Protected Setup Status, Network Name (SSID),
Security, and Passphrase are displayed at the bottom of
the screen.
NOTE:
If you have client devices that do not
support Wi-Fi Protected Setup, note the wireless
settings, and then manually configure those
client devices.
Wireless > Wireless Security
The Wireless Security settings configure 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 information
on setting up wireless security networks, refer to
“Chapter 2: Wireless Security.”
Wireless Security
Security Mode
Select the security method for your wireless network. If
you do not want to use wireless security, keep the default,
Disabled
.
WPA Personal
NOTE:
If you are using WPA or WPA2, each
device in your wireless network MUST use the
same WPA or WPA2 method and shared key, or
else the network will not function properly.

Wireless > Advanced Wireless Settings
This
Wireless > Advanced Wireless Settings
screen is used
to set up 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
5 GHz or 2.4 GHz Advanced Wireless
The same settings are available for the 5 GHz and 2.4 GHz
radio bands. The 5 GHz Advanced Wireless settings
configure the 5 GHz network you set up on the
Basic
Wireless Settings
screen, and the 2.4 GHz Advanced
Wireless settings configure the 2.4 GHz network you set
up on the
Basic Wireless Settings
screen.
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 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.
Basic Rate
The Basic Rate setting is not one, 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..
Transmission Rate
The rate of data transmission should
be set depending on the speed of your wireless network.
You can select from a range of transmission speeds, or you
can select
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. The default value is
Auto
.
CTS Protection Mode
CTS (Clear-To-Send) Protection
Mode should remain disabled unless you are having severe
problems with your wireless products not being able
to transmit to the Router in an environment with heavy
latency wireless traffic. This function boosts the Router’s
ability to catch all wireless transmissions but will severely
decrease performance. The default value is
Auto.
Beacon Interval
A beacon is a packet broadcast by the
Router to synchronize the wireless network. Enter a value
between 20 and 1000 milliseconds. The Beacon Interval
value indicates the frequency interval of the beacon. The
default value is
100
.
DTIM Interval
This value, between 3 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
3
.
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
Page 20 / 53
Chapter 3
Advanced Configuration
16
Simultaneous Dual-Band Wireless-N Router
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
.

IPSec Passthrough
Internet Protocol Security (IPSec) is
a suite of protocols used to implement secure exchange

Point-to-Point Tunneling Protocol
(PPTP) allows the Point-to-Point Protocol (PPP) to be
tunneled through an IP network. To allow PPTP tunnels to
