Networking :: Computer Name?

Hi,

Is there a way to set a computer name for my DSL PC?

I can only access it using the IP address but am wanting to use a computer name.

The computer Name shows up as unknown on my Router which means it can not detect one.

I do know that BOX works in DSL but i need it to be able to be able to access it on the network.

Sorry I am a Linux Newbie....
