This page is to determine which algorithm will be selected for wireless transmission rate.
Available settings are explained as follows:
Item Description
Channel Width
20 MHz - AP will use 20MHz for data transmission and
receiving between the AP and the stations.
Auto 20/40 MHz - VigorAP will scan for nearby wireless AP
to determine which channel width (20MHz or 40MHz) shall be
used to meet the air situation. Usually, 40MHz would have
better performance under the clean wireless environment (e.g.,
less wireless traffic / contention). When the air condition is not
satisfied (e.g., dirty air), 20MHz will be used by VigorAP
automatically to ensure smooth network transmission.
40 MHz - AP will use 40MHz for data transmission and
receiving between the AP and the stations.
Antenna
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.
Fragment Length
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
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.
Country Code
VigorAP broadcasts country codes by following the 802.11d
standard. However, some wireless stations will detect / scan
the country code to prevent conflict occurred. If conflict is
detected, wireless station will be warned and is unable to make
network connection. Therefore, changing the country code to
ensure successful network connection will be necessary for
