How can I use a wireless router on a non wireless internet connection?

Hello,I have a Linksys 2.4 GHz wireless router that I want to use on a non wireless internet. I was wondering how I could do this. Is there a way to convert it to non wireless?

there are usually a few Ethernet jacks on home routers; they are actually router/switch combos.

It should work as-is. Just plug your ethernet cable into the LAN ports... To be safe, log into the router and disable the wireless, to prevent unknown users from accessing it...
