Optimize WiFi/WiMAX coexistence: Setting this will lessen any possible conflict with WiFi in the 2.4 GHz band and an
attached WiMAX modem. If a WiMAX modem is attached to the router when the WiFi is enabled, the WiFi channel and
transmit power will be set to levels that optimize the performance of the WiMAX modem. If no WiMAX modem is attached,
then default channel and power settings will be used even if this is selected.
Aggressively optimize WiFi/WiMAX coexistence: Selecting this will allow the router to switch WiFi channels and power
levels to match changes in WiMAX modem operating frequencies. This may cause some attached WiFi clients to lose
their connection. This is disabled if WiFi as WAN is enabled, as the router will need to match the WiFi channel of the host
router.
TX Power: Normally the wireless transmitter operates at 100% power. In some circumstances, however, there might be a
need to isolate specific frequencies to a smaller area. By reducing the power of the radio, you can prevent transmissions
from reaching beyond your corporate/home office or designated wireless area.
RTS Threshold: When an excessive number of wireless packet collisions are occurring, wireless performance can be
improved by using the RTS/CTS (Request to Send/Clear to Send) handshake protocol. The wireless transmitter will begin
to send RTS frames (and wait for CTS) when data frame size in bytes is greater than the RTS Threshold. This setting
should remain at its default value.
Fragmentation Threshold: Wireless frames can be divided into smaller units (fragments) to improve performance in the
presence of RF interference and at the limits of RF coverage. Fragmentation will occur when frame size in bytes is greater
than the Fragmentation Threshold. This setting should remain at its default value. Setting the Fragmentation value too low
may result in poor performance.
DTIM: A DTIM is a countdown informing clients of the next window for listening to broadcast and multicast messages.
When the wireless router has buffered broadcast or multicast messages for associated clients, it sends the next DTIM
with a DTIM Interval value. Wireless clients detect the beacons and awaken to receive the broadcast and multicast
messages. The default value is 1. Valid settings are between 1 and 255.
Beacon: Beacons are packets sent by a wireless router to synchronize wireless devices. Specify a Beacon Period value
between 20 and 1000 milliseconds.
