I am pruchasing a new laptop that has a wifi built in. our desk top computer is already hooked up to our satalite internet (only high speed available in this rural but nice area). I've been reading up on wireless networking, but now am confused.. I don't want to share files, just the internet connection.
What do I need and how to hook it up? and do I have to hook up the desk top wireless or can I save money and still just plug it in?
