OK, if you are not doing anything fancy in your house, then you should just leave the modem / router to do its' thing and control DHCP. This means that it will give you an IP address, tell you IT is the way out on to the internet, and tell your operating system what name servers to use.

In order to do this, you need a DHCP client to 'ask' a DHCP server for those details. In Linux it's dhcpcd. I have it running on mine...

paully at thinkpad ~ $ pidof dhcpcd
2053

Here is my name server file...
paully at thinkpad ~ $ cat /etc/resolv.conf
nameserver 212.159.6.10
nameserver 212.159.6.9

...which just happens to be PlusNet's nameservers.

Here is my way out onto the 'net...
paully at thinkpad ~ $ route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
0.0.0.0         192.168.0.1     0.0.0.0         UG    0      0        0 eth0
127.0.0.0       127.0.0.1       255.0.0.0       UG    0      0        0 lo
192.168.0.0     0.0.0.0         255.255.255.0   U     0      0        0 eth0

...so you can see the modem / router is on the classic 192.168.0.1 address.

OK, what computers do you have where you are now?
