preamble with 56 bit sync field instead of long preamble
with 128 bit sync field. However, some original 11b
wireless network devices only support long preamble. Click
Enable to use Long Preamble if needed to communicate
with this kind of devices.
Packet-OVERDRIVE This feature can enhance the performance in data
transmission about 40%* more (by checking
Tx Burs t). It
is active only when both sides of Access Point and Station
(in wireless client) invoke this function at the same time.
That is, the wireless client must support this feature and
invoke the function, too.
Note: Vigor N61 wireless adapter supports this function.
Therefore, you can use and install it into your PC for
matching with Packet-OVERDRIVE (refer to the following
picture of Vigor N61 wireless utility window, choose
Enable for TxBURST on the tab of Option ).
Note: * means the real transmission rate depends on the
environment of the network.
Tx Power Set the power percentage for transmission signal of access
point.
The greater the value is, the higher intensity of the
signal will be.
Rate Adaptation
Algorithm Wireless transmission rate is adapted dynamically. Usually,
performance of “new” algorithm is better than “old”.
Fragment Length
(256 – 2346)
Set the Fragment threshold of wireless radio. Do not modify
default value if you don’t know what it is, default value is
2346.
RTS Threshold (1 – 2347) Minimize the collision (unit is bytes) between hidden
stations to improve wireless performance.
Set the RTS threshold of wireless radio. Do not modify
default value if you don’t know what it is, default value is
2347.
After finishing all the settings here, please click OK to save the configuration.
