hmm... are there any label on the modem that says
192.168.1.254 / 192.168.1.1
192.168.0.10 / 192.168.0.1 something like that?

if it is 192.168.1.x, set your computer's IP to 192.168.1.60
if it is 192.168.0.x, set your computer's IP to 192.168.0.60

see if the connection can be established in this way.

once connected, open your browser, type 192.168.1.[x] on the address bar to enter the modem config page
(if it requires modem access code, it is usually labeled on the modem as well)
and set the PPPoE / DHCP location to the modem instead of the router


remember the settings so these can be reversed.


EDIT: telling us your internet provider can help (comcast/ AT&T..etc)
if lucky, the login info is still saved inside the modem
