list to access this device.
MAC Address:
Your Gateway identifies wireless PCs by their WiFi MAC Address. This address consists
of a string of 6 pairs of numbers 0-9 and letters A-F, such as 00 90 4B F0 FF 50. It is usually printed on
the WiFi card of the device (e.g. the PCMCIA card in a laptop). It can also be determined from a
Windows DOS prompt as explained below.
Enter the MAC addresses of the connected clients into the fields, and then click Apply to add them to the

Beacon Interval:
Set the period of beacon transmissions to allow mobile stations to locate and identify a BSS. The measure
unit is “time units” (TU) of 1024 microseconds. (Value range: 1~65535)
DTIM Interval:
The value you set here is used to inform mobile stations when multicast frames that have been buffered at
the Wireless Gateway will be delivered and how often that delivery occurs. (Value range: 1~255)
Fragmentation Threshold:
Set the number of the fragmenting frames to make the data to be delivered without errors induced by the
interference. Frames longer than the value you set here are fragmented before the initial transmission into
fragments no longer than the value of the threshold. (Value range: 256~ 2346)
RTS Threshold:
Set the value for sending a request to the destination. All the frames of a length greater than the threshold
that you set here will be sent with the four-way frame exchange. And, a length less than or equal to the
value that you set will not be proceeded by RTS. (Value range: 0~ 2347)
