how about working backwards, hook the cable to the modem then connect the modem to the computer and see if it connects. once you connect. get your ip address. write it down just in case you need it for later configuration...

if it connects then you move onto the router. connect it as you had it before. open a browser type in 192.168.1.1, this should get you to your router settings.

in the setup tab the first drop down menu should be automatic dhcp

your local ip should be 192.168.1.1 the default mask should be 255.255.255.0.
the rest of the settings you can follow through using the below link.

the modem connects with the computer and internet works fine, but when i add the router to it, the internet doesnt work... those instructions explain how things work... but it doesnt show me how to fix my problem.. plus it shows for windows xp and lower, i have vista... my router is somehow blocking the internet connection, theres like a firewall or something that doesnt let internet go through... tried disabling things in router at 192.168.1.1 but still no improvement... grrr
