Advanced Configuration
QoS Setup
QoS or Quality of Service allows your Router to help prioritize the data packet flow in your Router and network. This is very important for time sensitive applications such as VoIP
where it may help prevent dropped calls. Large amounts of non-critical data can be scaled so as not to affect these prioritized sensitive real-time programs. The basic QoS Setup
menu includes some commonly used network services for which QoS can be enabled.
QoS settings can be customized for wireless or Ethernet applications and services that are not included in those listed in the basic QoS menu. To view the QoS settings menu for
Wireless LAN, click the Wireless QoS button under Advanced QoS, see the description below. Likewise to configure QoS settings for the Ethernet LAN, click the LAN QoS button
to view the settings menu.
Basic QoS settings can be configured by checking any of the listed network applications
and entering the ports (Start Port/End Port) used for the application. Click Save Settings
to apply the QoS settings.
