| Wireless Settings |
| Allow you to change the wireless settings to fit an existing wireless network orto customize your wireless network. |
Wireless Band
Operating frequency band. Choose 2.4GHz for visibility to legacy
devices and for longer range. Choose 5GHz for least interference;
interference can hurt performance. This AP will operate one band at a
time. |
Mode
Select
a function mode to configure your wireless network. Function modes
include AP, WDS (Wireless Distribution System) with AP, WDS and
Wireless Client. Function modes are designed to support various
wireless network topology and applications. |
Network Name (SSID)
Also known as the Service Set Identifier, this is the name designated
for a specific wireless local area network (WLAN). The factory default
setting is "dlink". The SSID can be easily changed to connect to an
existing wireless network or to establish a new wireless network. |
SSID Visibility
Indicate whether or not the SSID of your wireless network will be
broadcasted. The default value of SSID Visibility is set to "Enable,"
which allow wireless clients to detect the wireless network. By
changing this setting to "Disable," wireless clients can no longer
detect the wireless network and can only connect if they have the
correct SSID entered. |
Auto Channel Selection
If you check Auto Channel Scan, everytime when AP is booting up, the AP
will automatically find the best channel to use. This is enabled by
default. |
Channel
Indicate the channel setting for the DAP-2553. By default, the AP is
set to Auto Channel Scan. The Channel can be changed to fit the channel
setting for an existing wireless network or to customize the wireless
network. |
Channel Width
Allows you to select the channel width you would like to operate in.
Select 20MHz if you are not using any 802.11n wireless clients. Auto
20/40MHz allows your to use both 802.11n and non-802.11n wireless
devices in your network |
Authentication
For added security on a wireless network, data encryption can be
enabled. There are several available Authentications type can be
selected. The default value for Authentication is set to "Open System".
|
Open System
For Open System authentication, only the wireless clients with the same
WEP key will be able to communicate on the wireless network. The Access
Point will remain visible to all devices on the network. |
Shared Key
For Shared Key authentication, the Access Point cannot be seen on the
wireless network except to the wireless clients that share the same WEP
key. |
WPA-Personal/WPA2-Personal/WPA-Auto-Personal
Wi-Fi Protected Access authorizes and authenticates users onto the
wireless network. It uses TKIP encryption to protect the network
through the use of a pre-shared key. WPA and WPA2 uses different
algorithm. WPA-Auto allows both WPA and WPA2. |
WPA-Enterprise/ WPA2-Enterprise/ WPA-Auto-Enterprise
Wi-Fi Protected Access authorizes and authenticates users onto the
wireless network. WPA uses stronger security than WEP and is based on a
key that changes automatically at a regular interval. It requires a
RADIUS server in the network. WPA and WPA2 uses different algorithm.
WPA-Auto allows both WPA and WPA2. |
Network Access Protection
Network Access Protection (NAP) is a feature of Windows Server 2008.
NAP controls access to network resources based on a client computer's
identity and compliance with corporate governance policy. NAP allows
network administrators to define granular levels of network access
based on who a client is, the groups to which the client belongs, and
the degree to which that client is compliant with corporate governance
policy. If a client is not compliant, NAP provides a mechanism to
automatically bring the client back into compliance and then
dynamically increase its level of network access. |
| LAN Settings |
| Also
referred as private settings, LAN settings allow you to configure the
LAN interface of the DAP-2553. The LAN IP address is private to your
internal network and is not visible to Internet. The default IP address
is 192.168.0.50 with a subnet mask of 255.255.255.0. |
Get IP From
The factory default setting is "Static IP (Manual)" which allows the IP
address of the DAP-2553 to be manually configured in accordance to the
applied local area network. Enable "Dynamic IP (DHCP)" to allow the
DHCP host to automatically assign the Access Point an IP address that
conforms to the applied local area network. |
IP Address
The default IP address is 192.168.0.50. It can be modified to conform
to an existing local area network. Please note that the IP address of
each device in the wireless local area network must be within the same
IP address range and subnet mask. Take the default DAP-2553's IP
address as an example, each station associated with the AP must be
configured with a unique IP address falling in the range of
192.168.0.*. "*" ranges from 0 to 255 but is 50 in this case. |
Subnet Mask
A mask used to determine what subnet an IP address belongs to. The default subnet setting is 255.255.255.0.
|
Default Gateway
Specify the gateway IP address of the local network.
|
| Performance |
| You
can customize the network radio to fit your needs by tuning radio
parameters in the performance section. Performance functions are
designed for advanced users who are familiar with 802.11 wireless
networks and radio configuration. |
Wireless
This option allows the user to enable or disable the wireless function.
|
Wireless Mode
This function allows you to select different combination of clients
that can be supported.Please note that when backwards compatibility is
enabled for legacy (802.11a/g/b) clients, degradation of 802.11n
wireless performance is expected. |
Data Rate
Indicates the base transfer rate of wireless adapters on the wireless
local area network (WLAN). The access point will adjust the base
transfer rate depending on the base rate of the connected device. If
there are obstacles or interference, the AP will step down the data
rate. |
Beacon Interval (25-500)
Beacons are packets sent by an access point to synchronize a wireless
network. Setting a higher beacon interval can help to save the power of
a wireless client while setting a lower one can help a wireless client
connect to an access point faster. A setting of 100 milliseconds is
recommended for most users. |
DTIM Interval (1-15)
DTIM Interval specifies the number of AP beacons between each Delivery
Traffic Indication Message (DTIM). It informs associated stations of
the next window for listening to broadcast and multicast messages. You
can specify a DTIM value range from 1 to 15. The AP will send the next
DTIM with the specified DTIM value to stations if there is any buffered
broadcast or multicast message. Stations hear the beacons and get ready
to receive the broadcast or multicast messages. The default value for
DTIM interval is 1. |
Transmit Power
This setting determines the power level of the wireless transmission.
Transmitting power can be adjusted to eliminate overlapping of wireless
area coverage between two access points where interference is a major
concern. The options are 100% (default), 50% (-3dB), 25% (-6dB), or
12.5% (-9dB). For example, if wireless coverage is intended for half of
the area, then select "50%" as the option. |
WMM (Wi-Fi Multimedia)
The Wi-Fi Multimedia feature improves the user experience for audio,
video and voice applications over a Wi-Fi network. WMM is based on a
subset of the IEEE 802.11e WLAN QoS standard. Enabling this feature
improves the user experience for audio and video applications over a
Wi-Fi. |
Ack TimeOut
You can specify an Ack Timeout value range from 25~200 in 2.4GHz and
48~200 in 5GHz to effectively optimize the throughput over long
distance links. The unit is in microseconds (ms). The default value is
set to 25 ms in 2.4GHz and 48ms in 5GHz. |
Short GI
Using a short (400ns) guard interval can increase throughput. However,
it can also increase error rates in some installations due to increased
sensitivity to radio-frequency reflections. Select the option that
works best for your installation. |
IGMP Snooping
Internet Group Management Protocol (IGMP) snooping allows the AP to
recognize IGMP queries and reports sent between routers and an IGMP
host (wireless STA). When IGMP snooping is enabled, the AP will forward
multicast packets to IGMP host based on IGMP messages passing through
the AP. |
Link Integrality
If the Ethernet connection between the LAN and the AP is disconnected,
the "Link Integrity" option when enabled will cause the wireless client
to automatically disassociate from the AP. |
Connection Limit
Connection limit is an option for load balancing. It allows you to share the wireless network traffic and client using multiple DAP-2553s. If this function is enabled, when the number of users exceeds the "user limit", the AP will not allow clients to associate with this AP.
|
User Limit (0-64)
Set the maximum amount of users allowed per access point. "10" is recommended for the typical user.
|
| Multi-SSID |
| Multiple
SSIDs are only supported in AP mode. One primary SSID and at most seven
guest SSIDs can be configured to allow virtual segregation stations
which share the same channel. |
| Furthermore, you can enable the VLAN State to allow the DAP-2553 to work with VLAN-supported switches or other devices. |
| When
the Primary SSID is set to Open System without encryption, the Guest
SSIDs can only be set to no encryption, WEP, WPA-Personal or
WPA2-Personal. |
| When the Primary SSID's
security is set to Open or Shared System WEP key, the Guest SSIDs can
be set to use no encryption, use three other WEP keys, WPA-Personal, or
WPA2-Personal. |
| When the Primary SSID's
security is set to WPA-Personal, WPA2-Personal, or WPA-Auto-Personal,
slot 2 and slot 3 are used. The Guest SSIDs can be set to use no
encryption, WEP, or WPA-Personal. |
| When
the Primary SSID's security is set to WPA-Enterprise, WPA2-Enterprise,
or WPA-Auto-Enterprise, the Guest SSIDs can be set to use any security. |
| VLAN |
| The
DAP-2553 supports VLANs. VLANs can be created with a Name and VID. Mgmt
(TCP stack), LAN, Primary / Multiple SSID and WDS Connection can be
assigned to VLAN as they are physical ports. Any packet that enters the
DAP-2553 without a VLAN tag will have a VLAN tag inserted with a PVID. |
| Wireless Intrusion Protection |
| The DAP-2553 allows users to set up wireless intrusion protection. |
| Scheduling |
| DAP-2553's radio can be scheduled by week or by individual days. |
| QoS |
| QoS
stands for Quality of Service for Wireless Intelligent Stream Handling,
a technology developed to enhance the experience of using a wireless
network by prioritizing the traffic of different applications. |
Enable QoS
Enable this option if you want to allow QoS to prioritize your traffic.
Priority Classifiers.
|
HTTP
Allows the access point to recognize HTTP transfers for many common
audio and video streams and prioritize them above other traffic. Such
streams are frequently used by digital media players. |
Automatic
When enabled, this option causes the access point to automatically
attempt to prioritize traffic streams that it doesn't otherwise
recognize, based on the behavior that the streams exhibit. This acts to
de-prioritize streams that exhibit bulk transfer characteristics, such
as file transfers, while leaving interactive traffic, such as gaming or
VoIP, running at a normal priority. |
Qos Rules
A
QoS Rule identifies a specific message flow and assigns a priority to
that flow. For most applications, the priority classifiers ensure the
right priorities and specific QoS Rules are not required. |
| QoS supports overlaps between
rules. If more than one rule matches a specific message flow, the rule
with the highest priority will be used. |
Name
Create a name for the rule that is meaningful to you.
|
Priority
The priority of the message flow is entered here. Four priorities are defined:
|
* BK: Background (least urgent).
* BE: Best Effort.
* VI: Video.
* VO: Voice (most urgent).
|
The protocol used by the messages.
|
Host 1 IP Range
The rule applies to a flow of messages for which one computer's IP address falls within the range set here.
|
Host 1 Port Range
The rule applies to a flow of messages for which host 1's port number is within the range set here.
|
Host 2 IP Range
The rule applies to a flow of messages for which the other computer's IP address falls within the range set here.
|
Host 2 Port Range
The rule applies to a flow of messages for which host 2's port number is within the range set here.
|
