(DTIM). A DTIM is a countdown that informs clients about the next window for
listening to broadcast and multicast messages. The default value is 1.
Note: The DTIM is a multiple of the Beacon (TIM), so if the DTIM is set to 3, a DTIM
message is sent with every third Beacon.
Preamble Type Tells the receiver that data is on the way. The preamble allows the receiver to
acquire the wireless signal and synchronize itself with the transmitter. Select Long
Preamble or Short Preamble. Long Preamble can provide better wireless LAN
compatibility with legacy devices, while Short Preamble can provide better WLAN
performance.
Tx Power Lets you increase or decrease transmit power. Higher transmit power may prevent
connections to the network, while the lower transmit power can prevent clients
from connecting to the device.
Distance Specify the distance between Access Points and clients. Longer distances may drop
high‐speed connections.
Layer 2 Isolation Enable or disable Layer 2 Isolation. Layer 2 isolation prevents communication and
data sharing between wireless stations associated with different Access Points.
5.6.2 Advanced Settings (Client Bridge / Client Router)
Fragment Threshold Specify the maximum packet size during transmission. If a large number of clients are
accessing the WLAN, specify a small value to avoid collisions.
RTS Threshold RTS threshold is a trigger to engage the exchange of RTS and CTS messages between
the Access Point and client. The trigger is a type of “handshaking” approach that
provides an additional layer of control over the use of the shared medium by
indicating the amount of time a wireless device, attempting to send, will wait for a
recipient to acknowledge that it is ready. If the packet size is smaller than the RTS
threshold, the wireless router will not use the RTS/CTS mechanism to send the
