Please provide a little more detail. And do not "bump," it's against the forum rules.
As a first guess, you will have to establish a WiFi network in your home or workplace. Each machine will need WiFi hardware. You will either need a WiFi router / access point to serve as the controller of the network (I got one for free with my Internet service, since it's built into the modem/router), or to set up an ad-hoc network between the new machines.
Some useful details would be: are you already on a local wired network, what kind of hardware do you have to attach to the Internet, does either machine already have WiFi hardware? What do you want to do: share the computer's internet connection with the mobile, transfer files, ??
