Transmission Rates: You may select transmission rate to “1-2Mbps”, “1-2-5.5-11Mbps” or
“1-2-5.5-11-22Mbps”.
Preamble Type: The preamble defines the length of the CRC block for communication
between the Access Point and roaming Network Card. Long preamble ensure the network
card to communicate with access point more reliably. Verify that you have selected the
appropriate preamble type and click the Apply button to set it. Note: High network traffic
areas should use the short preamble type
SSID Broadcast: This allows the AP to broadcast its SSID. Other wireless client with site
survey function can easily know this SSID and use this SSID to connect your access point.
To secure your wireless network from unauthorized users, please disable this function.
Beacon Interval: Specify the Beacon Interval value. Enter a value between 1 and 1000.
Beacons are packets sent by an Access Point to synchronize a wireless network.
RTS Threshold: Use this field to specify a value for the RTS Threshold. Enter a value
between 256 and 2432. This value should remain at its default setting of 2,432. Should you
encounter inconsistent data flow, only minor modifications are recommended.
Fragmentation Threshold: This field is used to specify the fragmentation threshold. Enter a
value between 256 and 2346. If you experience a high packet error rate, try to slightly
increase your Fragmentation Threshold. The value should remain at its default setting of
2,346. Setting the Fragmentation Threshold too low may result in poor performance.
DTIM Interval: Specify the Beacon Rate. Enter a value between 1 and 65535 that specifies
the Delivery Traffic Indication Message (DTIM). A DTIM is a countdown informing clients of
the next window for listening to broadcast and multicast messages. When the AP has
buffered broadcast or multicast messages for associated clients, it sends the next DTIM with
a DTIM Interval value. AP Clients hear the beacons and awaken to receive the broadcast
and multicast messages.
Antenna Selection: These settings determine whether either or both antennas will be used
to receive data. The default setting is Diversity. This setting is uses both antennae to help
overcome multi-path distortion. There are two antennas on WAP-1966. One is visible
from outside which is right antenna.
4X mode: Enable or disable 4X mode. Enable 4X mode will raise the wireless performance
to 44Mbps equivalent. But, please be noted, both wireless AP and client must be using TI
chipset and configured 4X mode enabled to make it effective.
