NOTE
After you configure the QoS settings, you must click Apply to apply the changes
and to save the settings. Changing some settings might cause the access point to
stop and restart system processes. If this happens, wireless clients will temporarily
lose connectivity. We recommend that you change access point settings when
WLAN traffic is low.
