WMM
On the Wi-Fi / WMM page, you can enable the Wi-Fi Multimedia function.
The WMM function implements the QoS features for Wi-Fi networks. It helps to improve the
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 Apply button.

!
All needed settings for the WMM function are specified in the device'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).
• AC_VO (Voice).
Parameters of the Access Categories are defined for both the router itself (in the Parameters of
Access Point section) and wireless devices connected to it (in the Parameters of Station
section).
