Enable A-MSDU 

Aggregation

Select this to enable A-MSDU aggregation.

Mac Service Data Unit (MSDU) aggregation collects Ethernet frames without any of 
their 802.11n headers and wraps the header-less payload in a single 802.11n MAC 
header. This method is useful for increasing bandwidth throughput. It is also more 
efficient than A-MPDU except in environments that are prone to high error rates.

A-MSDU Limit

Enter the maximum frame size to be aggregated.

RTS/CTS 

Threshold

Use RTS/CTS to reduce data collisions on the wireless network if you have wireless 
clients that are associated with the same AP but out of range of one another. When 
enabled, a wireless client sends an RTS (Request To Send) and then waits for a CTS 
(Clear To Send) before it transmits. This stops wireless clients from transmitting 
packets at the same time (and causing data collisions). 

A wireless client sends an RTS for all packets larger than the number (of bytes) that 
you enter here. Set the RTS/CTS equal to or higher than the fragmentation threshold 
to turn RTS/CTS off.

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 low-power 
mode before waking up to handle the beacon. A high value helps save current 
consumption of the access point. 

DTIM

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. This 
value can be set from 1 to 255.

Enable Signal 

Threshold

Select the check box to use the signal threshold to ensure wireless clients receive good 
throughput. This allows only wireless clients with a strong signal to connect to the AP.

Clear the check box to not require wireless clients to have a minimum signal strength 
to connect to the AP.

Station Signal 

Threshold

Set a minimum client signal strength. A wireless client is allowed to connect to the AP 
only when its signal strength is stronger than the specified threshold. 

-20 dBm is the strongest signal you can require and -76 is the weakest.

Disassociate 

Station 

Threshold

Set a minimum kick-off signal strength. When a wireless client’s signal strength is 
lower than the specified threshold, the USG disconnects the wireless client from the AP. 

-20 dBm is the strongest signal you can require and -90 is the weakest.

Allow Station 

Connection after 

Multiple Retries

Select this option to allow a wireless client to try to associate with the AP again after it 
is disconnected due to weak signal strength.

Station Retry 

Count

Set the maximum number of times a wireless client can attempt to re-connect to the 
AP.

Multicast Settings

Use this section to set a transmission mode and maximum rate for multicast traffic.

Transmission 

Mode

Set how the AP handles multicast traffic.

Select 

Multicast to Unicast

 to broadcast wireless multicast traffic to all of the wireless 

clients as unicast traffic. Unicast traffic dynamically changes the data rate based on the 
application’s bandwidth requirements. The retransmit mechanism of unicast traffic 
provides more reliable transmission of the multicast traffic, although it also produces 
duplicate packets.

Select 

Fixed Multicast Rate

 to send wireless multicast traffic at a single data  rate. 

You must know the multicast application’s bandwidth requirements and set it in the 
following field.

Multicast Rate 

(Mbps)

If you set the multicast transmission mode to fixed multicast rate, set the data rate for 
multicast traffic here. For example, to deploy 4 Mbps video, select a fixed multicast 
rate higher than 4 Mbps.
