Some modems install internally, others require a cable.
Your question presupposes that you have subscribed to cable internet service, and that the provider has run a cable to your home. It also presupposes that you have a cable modem. If these suppositions are correct, you just have to run coax between the cable jack on the wall and the cable modem. Then you need to connect the modem to your computer via USB, FireWire, or whatever interface your modem and computer have in common. FriPilot

is it a straight ethernet or a crossover? i am using a Motorola SURFboard SB5120. You'll only need a straight ethernet cable for that.
Yes, if you connect them using a LAN cable.
If the instructions say that if you are using a modem you may need to manually connect to the Internet. What this means is that you might have to connect one end of an Ethernet cable into the modem and the other end into the back of your device.
You need to connect a modem using the modem port and the telephone cable.
You can buy the cable modem itself but you have to have a service provider for it.
Find a Broadband or DSL internet provider or if you already have one and are already using it connect a router to your modem. Then simple connect an ethernet cable from your modem to your router and one from your router to your PS3. The cable that was going from the modem to your computer now goes from your router to your computer. If you are not using the internet service before then just connect th ethernet cable from your new modem to the PS3. Then if you do get a computer just buy the router and the ethernet cables then.
