Beacons are packets sent by an access point to synchronize a wireless network. Specify a value in milliseconds. The default

(

100

) is recommended. Setting a higher beacon interval can help to save the power of wireless clients, while setting a lower

one can help a wireless client connect to an access point faster.

Indicate the base transfer rate of wireless adapters on the wireless LAN. The AP 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 rate. This option

is enabled in Mixed 802.11g and 802.11b mode (for 2.4 �Hz) and 802.11a only mode (for 5 �Hz). The choices available

±Maximum wireless signal rate derived from IEEE Standard 802.11g, 802.11a and Draft 802.11n specifications. Actual data throughput will vary. Network conditions and

environmental factors, including volume of network traffic, building materials and construction, and network overhead, lower actual data throughput rate. Environmental

conditions will adversely affect wireless signal range.

WMM stands for Wi-Fi Multimedia. Enabling this feature will improve the user experience for audio and video applications

over a Wi-Fi network.

Short GI:

Select

. Enabling a short guard interval can increase throughput. However, be aware that it can also

increase the error rate in some installations due to increased sensitivity to radio-frequency installations.

IGMP Snooping:

Select

Enable

or

Disable

. Internet �roup Management Protocol allows the AP to recognize I�MP queries and

reports sent between routers and an I�MP host (wireless STA). When I�MP snooping is enabled, the AP will forward

multicast packets to an I�MP host based on I�MP messages passing through the AP.

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. For example,

if wireless coverage is intended for half of the area, then select 50% as the option. Use the pull-down menu to select

accessing this device. The exact number is entered in the User Limit field below. This feature allows the user to share

the wireless network traffic and the client using multiple APs. If this function is enabled and when the number of

users exceeds this value, or the network utilization of this AP exceeds the percentage that has been specified, the

DAP-2590 will not allow clients to associate with the AP.
