If the router does not detect the type of Internet connection you have, you
will see a list of connection types. Select your Internet connection type. This
information can be obtained from your ISP (Internet Service Provider).
Select DHCP Connection (Dynamic IP Address) if your Internet connection
automatically provides you with an IP address. This option is commonly used
for cable modem services.
Click Next to continue.
If the router detected PPPoE or you selected Username/Password Connection
(PPPoE), enter your PPPoE username and password supplied by your ISP.
Click Next to continue.
Note: Make sure you remove your PPPoE software from your computer. The
software is no longer needed and will not work through a router.
