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 (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.
Set the Fragment threshold. 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. Do not modify default value if you
don't know what it is, default value is 2347.
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.
