Note:

If you don't know how to choose the appropriate connection type, click the

Detect

button to allow

the router to automatically search your Internet connection for servers and protocols. The

connection type will be reported when an active Internet service is successfully detected by the

router. This report is for your reference only. To make sure the connection type your ISP provides,

please refer to the ISP. The various types of Internet connections that the router can detect are as

follows:



PPPoE

-

Connections which use PPPoE that requires a user name and password.



Dynamic IP

-

Connections which use dynamic IP address assignment.



Static IP

-

Connections which use static IP address assignment.

The router cannot detect PPTP/L2TP/Big Pond connections with your ISP. If your ISP uses one

of these protocols, then you must configure your connection manually.
