Description
20 MHz- The device will use 20MHz for data transmission and
receiving between the AP and the stations.
Auto 20/40 MHz–The AP will scan for nearby wireless AP, and then
use 20MHz if the number of AP is more than 10, or use 40MHz if it's
not.
40 MHz- The device will use 40MHz for data transmission and
receiving between the AP and the stations. It is for wireless LAN
2.4GHz only.
Auto 20/40 /80 MHz - The device will use 20/40/80 MHz channel
bandwidth for data transmission and receiving between the AP and
the stations.
This feature can enhance the performance in data transmission about
40%* more (by checking Tx Burst). 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.
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).
VigorAP can be attached with two antennas to have good data
transmission via wireless connection. However, if you have only one
antenna attached, please choose 1T1R.
The default setting is the maximum (100%). Lowering down the value
may degrade range and throughput of wireless.
Wireless transmission rate is adapted dynamically. Usually,
performance of "new" algorithm is better than "old".
Set the Fragment threshold of wireless radio. Do not modify default
value if you don't know what it is, default value is 2346.
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.
VigorAP broadcasts country codes by following the 802.11d standard.
