Advanced Wireless
This page allows you to configure the fragmentation threshold, RTS threshold,
beacon period, transmit power, DTIM interval, wireless isolation, WMM and WDS
(wireless distribution system).
°
Transmit Power
: You may control the output power of the device by
selecting a value from the drop-down list. This feature can be helpful in
restricting the coverage area of the wireless network.
°
Beacon Period
: Beacons are packets sent by a wireless Access Point to
synchronize wireless devices. Specify a Beacon Period value between 20 and
1000. The default value is set to 100 milliseconds.
°
RTS Threshold
: Packets over the specified size will use the RTS/CTS
mechanism to maintain performance in noisy networks and preventing hidden
nodes from degrading the performance. Specify a value between 1 and
65535. The default value is 2346.

°
Fragment Threshold
: Packets over the specified size will be fragmented in
order to improve performance on noisy networks. Specify a value between
256 and 65535. The default value is 2346.
°
DTIM Interval
: A DTIM is a countdown informing clients of the next window
for listening to broadcast and multicast messages. When the wireless Access
Point has buffered broadcast or multicast messages for associated clients, it
sends the next DTIM with a DTIM Interval value. Wireless clients detect the
beacons and awaken to receive the broadcast and multicast messages. The
default value is 1. Valid settings are between 1 and 255.
°
Wireless Isolation
: Place a check in this box in order to prevent associated
wireless clients from communicating with each other.
°
WMM Enable
: Enable WMM in order to help control latency and jitter when
transmitting multimedia content over a wireless connection.
°
WDS
: Place a check in this box to enable WDS (Wireless Distribution
System). When WDS is enabled, this access point functions as a wireless
repeater and is able to wirelessly communicate with other APs via WDS links.
Note
that WDS is incompatible with WPA -- both features cannot be used at
the same time. A WDS link is bidirectional; so this AP must know the MAC
Address (creates the WDS link) of the other AP, and the other AP must have a
WDS link back to this AP. Make sure the APs are configured with same
channel number.
°
WDS AP MAC Address
: Specify one-half of the WDS link. The other AP must
also have the MAC address of this AP to create the WDS link back to this AP.

button to store these changes.
Advanced Network
In this section you can configure the UPnP, WAN Ping, WAN port speed, multicast
streams, and PPPoE pass-through settings.
°
Enable UPnP
: Place a check in this box to enable UPnP.
UPnP is short for
Universal Plug and Play, which is a networking architecture that provides
compatibility among networking equipment, software, and peripherals. This
router has optional UPnP capability, and can work with other UPnP devices
and software.
°
Allow Users to disable Internet Access
: Place a check in this box if you
would like to allow to user to terminate the WAN session.
°
Allow Users to modify Virtual Server Mappings
: Place a check in this box
if you would like the users to add, modify, or delete server mapping entries.

°
WAN Port Speed
: You may select a WAN port speed from the drop-down
list. It is recommended that you select
Auto
.
°
Enable Multicast Streams
: Place a check in this box to enable multicast
streams. The router uses the IGMP protocol to support efficient multicasting -
- transmission of identical content, such as multimedia, from a source to a
number of recipients. This option must be enabled if any applications on the
LAN participate in a multicast group. If you have a multimedia LAN application
that is not receiving content as expected, try enabling this option.
°
Enable PPPoE Pass Through
: Place a check in this box to enable PPPoE
pass-through. This option controls whether LAN computers can act as PPPoE
clients and negotiate the PPP sessions through the router over the WAN
ethernet link. Enabling this option allows LAN computers to act as PPPoE
clients. Disabling this option prevents LAN computers from establishing PPPoE
pass-through connections.

4.3 Firewall
Virtual Server
The Virtual Server option gives Internet users access to services on your LAN.
This feature is useful for hosting online services such as FTP, Web, or game
servers. For each Virtual Server, you define a public port on your router for
redirection to an internal LAN IP Address and LAN port.
°
Enable
: Place a check in this box to enable the virtual server rule.
°
Name
: Assign a meaningful name to the virtual server, for example Web
Server. Several well-known types of virtual server are available from the
Application Name
drop-down list. Selecting one of these entries fills some of
the remaining parameters with standard values for that type of server.
°
IP
Address
: Specify the IP address for the virtual server entry.
°
Protocol
: Specify a protocol or select one from the drop-down list.
°
Public
Port
: Specify the public port number.
°
Private
Port
: Specify the private port number.
°
Schedule
: Select a
schedule
,
Always,
or
Never
from the drop-down list. If
a schedule does not exist, you may create it in the Tools > Schedule section.
°
Inbound
Filter
: Select an inbound filter from the drop-down list. If an
inbound filter does not exist, you may create it from Advanced > Inbound
Filter section.
Click on the
Save
button to insert the entry into the Virtual Server list.

Special Application
An application rule is used to open single or multiple ports on your router when
the router senses data sent to the Internet on a trigger port or port range. An
application rule applies to all computers on your internal network.
°
Enable
: Place a check in this box to enable the special application rule.
°
Name
: Assign a meaningful name to the virtual server, for example Web
Server. Several well-known types of virtual server are available from the
Application Name
drop-down list. Selecting one of these entries fills some of
the remaining parameters with standard values for that type of server.
°
Triggering Ports
: Specify the outgoing port range that is used by the
application.
°
Firewall Ports
: Specify the port range that you would like to open for
Internet traffic.
°
Schedule
: Select a
schedule
,
Always,
or
Never
from the drop-down list. If
a schedule does not exist, you may create it in the Tools > Schedule section.
Click on the
Save
button to insert the entry into the Special Applications list.
