QoS Engine
This option is disabled by default. Enable this
option for better performance and experience with
online games and other interactive applications,
such as VoIP.
This option should be enabled when you have a
slow Internet uplink. It helps to reduce the impact
that large low priority network packets can have
on more urgent ones.
This option is enabled by default when the QoS
Engine option is enabled. This option will allow
your router to automatically determine the uplink
speed of your Internet connection.
This displays the detected uplink speed.
The speed at which data can be transferred from the router to your ISP. This is determined by your ISP. ISP’s often speed
as a download/upload pair. For example, 1.5Mbits/284Kbits. Using this example, you would enter 284. Alternatively you can
test your uplink speed with a service such as www.dslreports.com.
By default, the router automatically determines whether the underlying connection is an xDSL/Frame-relay network or some
other connection type (such as cable modem or Ethernet), and it displays the result as Detected xDSL or Frame Relay Network.
If you have an unusual network connection in which you are actually connected via xDSL but for which you configure either
“Static” or “DHCP” in the Internet settings, setting this option to xDSL or Other Frame Relay Network ensures that the router
will recognize that it needs to shape traffic slightly differently in order to give the best performance. Choosing xDSL or Other
Frame Relay Network causes the measured uplink speed to be reported slightly lower than before on such connections, but
gives much better results.
When Connection Type is set to automatic, the automatically detected connection type is displayed here.

The QoS Engine option helps improve your network gaming performance by prioritizing applications. By default the
QoS Engine settings are disabled and application priority is not classified automatically.
