I'd hate to have to re-setup my ADSL connection over and over. Pending on what type of modem your have common usernames and passwords could be
*blank/*blank
admin/admin
root/highspeed
admin/*blank
just go to whatismyip.com then take your IP address and insert it into your browser address bar and your should be at the login page for your modem.
If you already use a router login to your router using your gateway ip address your machine has. you can find your gateway using the command "netstat -nr" in a terminal. They are usually
192.168.0.1
192.168.1.1
192.168.2.1
When you get there complete the WAN setup. on My Belkin N+ its under "Internet WAN" and the setup option your looking for is "Connection type" and your are possibly using PPPoE .
Just go from there dude. good luck
