Today i got ACT Fibernet activated and i am having Asus DSL N10E Modem Router. I tried disabling DHCP and connected in one LAN input. But i cant find where to define the user id and password in the setup and other related setup. Tried different options, nothing is working. Please help me configure it.

Not possible. Please get a proper router.
