QoS
This displays the QoS priority level associated with the SSID.
This field is configurable only when you enable 802.1Q VLAN tagging in the System >
General screen and select the Tag check box in this screen.

Beacon Interval
When a wirelessly networked device sends a beacon, it includes with it a beacon
interval. This specifies the time period before the device sends the beacon again. The
interval tells receiving devices on the network how long they can wait in lowpower
mode before waking up to handle the beacon. A high value helps save current
consumption of the access point.

DTIM Interval
Delivery Traffic Indication Message (DTIM) is the time period after which broadcast
and multicast packets are transmitted to mobile clients in the Active Power
Management mode. A high DTIM value can cause clients to lose connectivity with the
network.

Output Power
Set the output power of the NWA in this field. If there is a high density of APs in an
area, decrease the output power of the NWA to reduce interference with other APs.
Select one of the following Full (Full Power), 50%, 25%, 12.5% or Min (Minimum).
See the product specifications for more information on your NWA’s output power.

Select Dynamic to have the AP automatically use short preamble when wireless
adapters support it, otherwise the AP uses long preamble.

RTS/CTS Threshold
(Request To Send) The threshold (number of bytes) for enabling RTS/CTS handshake.
Data with its frame size larger than this value will perform the RTS/CTS handshake.
Setting this attribute to be larger than the maximum MSDU (MAC service data unit)
size turns off the RTS/CTS handshake. Setting this attribute to its smallest value (1)
turns on the RTS/CTS handshake.

protection mode
protection mode
You can use CTS to self or RTS-CTS protection mechanism to reduce conflicts with
other wireless networks or hidden wireless clients. The throughput of RTS-CTS is
much lower than CTS to self. Using this mode may decrease your wireless
performance.

A-MPDU aggregation
This field is available only when 802.11 b/g/n is selected as the Wireless Mode.
Select Enable to allow the grouping of several A-MSDUs (Aggregate MAC Service
Data Units) into one large A-MPDU (Aggregate MAC Protocol Data Unit). This function
allows faster data transfer rates.

Short GI
This field is available only when 802.11 b/g/n is selected as the Wireless Mode.
Select Enable to use Short GI (Guard Interval). The guard interval is the gap
introduced between data transmission from users in order to reduce interference.
Reducing the GI increases data transfer rates but also increases interference.
Increasing the GI reduces data transfer rates but also reduces interference.

Rates Configuration
This section controls the data rates permitted for clients.
For each Rate, select an option from the Configuration list. The options are:
•
Basic (1~11 Mbps only): Clients can always connect to the access point at this
speed.
•
Optional: Clients can connect to the access point at this speed, when permitted
to do so by the AP.
•
Disable: Clients cannot connect to the access point at this speed.
