DESCRIPTION
Enter the maximum number of frames to be aggregated each time.
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.
Enter the maximum frame size to be aggregated.
This field is available when you select 5G in the 802.11 Band field.
DFS (dynamic frequency selection) allows an AP to detect other devices in the same
channel. If there is another device using the same channel, the AP changes to a
different channel, so that it can avoid interference with radar systems or other wireless
networks.
Select this option to disable DFS on the AP.
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.
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.
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.
Set the output power of the AP in this field. If there is a high density of APs in an area,
decrease the output power of the NWA5160N to reduce interference with other APs.
Select one of the following 100%, 50%, 25%, or 12.5%. See the product
specifications for more information on your NXC's output power.
Note: Reducing the output power also reduces the NXC's effective broadcast radius.
Use the Received Signal Strength Indication (RSSI) threshold to ensure wireless clients
receive good throughput. This allows only wireless clients with a strong signal to
connect to the AP.
Select the check box and set a minimum client signal strength for connecting to the AP.
-20 dBm is the strongest signal you can require and -76 is the weakest.
Clear the check box to not require wireless clients to have a minimum signal strength
to connect to the AP.
