Is the modem owned by the telco or cable company? Do you have Cable or DSL?
In my experience many of the routers require setup and possibly software. Are you connecting to the router using a network patch cable, or USB?
Connecting directly to the modem temporarily will eliminate the router from the equation but will leave you exposed during the period of time you are directly connected. If you try that then keep that time to a minimum.
The connection between the modem and the router may require a crossover type network cable. Hard to tell the difference by just looking but there are 8 wires inside the cable and they are wired differently at one end on a crossover cable.
Then there is an uplink port on the router which is normally used to connect to a switch for expanding the number of ports (users) available.
All of these items can impact on how and if the whole system works.
