Wireless HELP!

Hi, I'm very new to this wireless networking business.. but I am trying to setup an in home wireless network..

My situation:
I'm using Yahoo DSL through my desktop... and I have to login on startup to make the DSL active
However, I want to create a wireless network in my house but I'm not sure how that works when the broadband itself requires me to login..
I'm thinking I will buy a wireless router, connect it to my DSL modem but then I'm at a loss to how the network will remain functional when my desktop is off

if someone could walk me through this process? thank you very much!

You are thinking right The solution is to buy a wireless router. You connect this router directly to the DSL-modem, and then set up the router to connect with your username and password. Then, when any computer tries to access internet, the router will connect to your internet provider, and share the connection, regardless of your desktop computer.
