D-Link DGL-4500 User Manual
Section - Configuration
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.
