Beacon Interval: Enter the time in milliseconds between beacon
transmissions. The default interval is 100 milliseconds.
Fragmentation Threshold: This is the maximum length of the frame, in
bytes, beyond which packets must be broken up (fragmented) into two
or more frames. Collisions occur more often for long frames because
while sending them they occupy the channel for a longer time. The
default value is 2346, which effectively disables fragmentation.
RTS Threshold: The Request to Send (RTS) threshold is the packet size
in bytes above which the DWR-923 is required to check the
transmitting frames to determine if RTS/Clear to Send (CTS) handshake
is required with the receiving client. Using a small value causes RTS
packets to be sent more often, consuming more of the available
bandwidth, therefore reducing the apparent throughput of the
network packets. The default value is 2346, which effectively disables
RTS.
Transmit Power: Enter a value in dBm for the default transmit power
level.
Channel: The wireless channel that the DWR-923 will broadcast on.
This specifies the radio frequency used to transmit wireless frames.
Select a channel from the list or choose Auto to let the system
determine the best channel to use based on environmental noise levels
for all available channels.
Wireless Mode: Select the 802.11 modulation technique. The
DWR-923 supports 802.11 b/g/n Wi-Fi modes.
Bandwidth: When you choose "ng" as your wireless mode, you may
choose a Wi-Fi bandwidth for this product from HT20, HT40- and
HT40+. Higher bandwidth indicates a higher throughput of your
