Advance Configuration
Radio Setting
Data Rate: You can fix the data rate to different values as 11Mbps or 6Mbps. However it is
recommended to set the setting to “Best” for ExpressPort adapter to determine the best data rate
to be use.
Transmit Power: Sometimes, it is useful to decrease the coverage range of each ExpressPort
adapter, so that more ExpressPort adapter can be located together without interference to one
another.
Beacon Interval
: Choose between 20 to 1000.Low Beacon Interval will make the association and
roaming process very responsive. However, throughput will decrease, so it is necessary to strike
a balance. Typical Beacon Interval is set to 100ms.
Data Beacon Rate (DTIM): Choose between 1 to 16384.This is always a multiple of the beacon
interval. It determines how often the beacon contains a delivery traffic indication message (DTIM).
The DTIM tells power-save client devices that a packet is waiting for them.
Fragment Length
: Specifies the fragment length. Enter a value between 256 and 2346.
RTS/CTS Threshold: Enter a value between 256 and 2346
Short Preamble
: Enable to use Short Preamble in the Wireless LAN packet headers. Most
manufacturers implement long preambles. Even if there is a mismatch between ExpressPort
adapter and the client, they can still connect well and the mismatch may not be noticeable to
most users. Do not change this setting without seeking advice.
Allow 2.4GHz 54Mbps Stations Only
: Use this radio button to enable or disable the association
of 2.4 Ghz 54 Mbps STA only.
Protection Mode: Select None, Always or Auto
Protection Rate: Select 1Mbps, 2Mbps, 5.5Mbps or 11Mbps
Protection Type: Select either CTS only or RTS-CTS
Short Slot Time: Enable or disable short time slot usage
