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.
Select the needed action from the drop-down list in the Work mode section to configure the
WMM function.
• Auto: The settings of the WMM function are configured automatically (the value is
specified by default).
• Manual: The settings of the WMM function are configured manually. When this value is
selected, the Access Point and Station sections are displayed on the page.
Figure 125. The page for configuring the WMM function.
!
All needed settings for the WMM function are specified in the device's system. Changing
parameters manually may negatively affect your WLAN!
The WMM function allows assigning priorities for four Access Categories (AC):
• BK (Background), low priority traffic (print jobs, file downloads, etc.).
• BE (Best Effort), traffic from legacy devices or devices/applications that do not support
QoS.
• VI (Video).
• VO (Voice).
