Basic Settings
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-2590. 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-2590. 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-2590 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-2590'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.
Advanced Settings
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-2590s. If this function is enabled, when the number of users exceeds the "user limit," or the network utilization of this AP exceeds the percentage that you specify, 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.
Network Utilization
Set the maximum utilization of this access point for service. The DAP-2590 will not let any new client associate with the AP if the utilization exceeds the value the user specified. "100%" is recommended.
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-2590 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-2590 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-2590 without a VLAN tag will have a VLAN tag inserted with a PVID.
Wireless Intrusion Protection
The DAP-2590 allows users to set up wireless intrusion protection.
Scheduling
DAP-2590'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
