A quick look at the router's specifications tell me that it is a DSL router. Which means you are supposed to replace your current modem with this router. This router does not have ethernet WAN port. The four ports are LAN ports. So you can not put the modem on router's WAN side.
On a side note, this router looks like decent choice for home based networking. Even I have been looking for some good DSL router with wireless functionality for some time. :-) Onkar -- ubuntu-in mailing list ubuntu-in@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-in
