Note: * means the real transmission rate depends on the
environment of the network.
Antenna
Vigor router 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.
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.
WMM Capable
WMM is an abbreviation of Wi-Fi Multimedia. It defines
the priority levels for four access categories derived from
802.1d (prioritization tabs). The categories are designed
with specific types of traffic, voice, video, best effort and
low priority data. There are four accessing categories -
AC_BE , AC_BK, AC_VI and AC_VO for WMM.
To apply WMM parameters for wireless data transmission,
please click the Enable radio button.
APSD Capable
APSD (automatic power-save delivery) is an enhancement
over the power-save mechanisms supported by Wi-Fi
networks. It allows devices to take more time in sleeping
state and consume less power to improve the performance
by minimizing transmission latency.
The default setting is Disable.
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. 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. Do not modify default
value if you
don’t know what it is, default value is 2347.
Country Code
Vigor router 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 some clients.
After finishing all the settings here, please click OK to save the configuration.
