quality of data transfer over Wi-Fi networks by prioritizing different types of traffic.
To enable the function, select the WMM checkbox and click the Change button.

All needed settings for the WMM function are specified in the router's system. It is
recommended not to change the default values.
The WMM function allows assigning priorities for four Access Categories (AC):
AC_BK (Background), low priority traffic (print jobs, file downloads, etc.).
•
AC_BE (Best Effort), traffic from legacy devices or devices/applications that do not support
•
QoS.
AC_VI (Video).

Parameters of the Access Categories are defined for both the router itself (in the WMM

Parameters of Station section).
