How do I hook up XBOX 360 and a computer to the internet at the same time?

Question

I know I need a router, but I dont know exactly what is involved.... d o i need anything else? do you just plug ethernet cables into the router and it works right out of the box, or do i have to set stuff up? any other advice/info you think i need to know?

also, would something like this be ok:

thanks in advance for your input

Answer 1

In addition to what Joe said, the router will most likely come with some software that you will have to install on your pc. I have a D-Link router and have had no problems with it. My 360 worked right away when I hooked it up.

Answer 2

After you get a router just plug the xbox 360 ethernet cable into the router just like you would a second computer, if you have any problems the xbox 360 has a network test you can run.
