Though a great leap forward for Internet technology, Wireless Fidelity is relatively simple to set up. Most laptop computers and some desktop computers manufactured today come with wireless capabilities. You need only to activate their wireless function. However, if it your computer is older and does not come equipped with this ability, it is a relatively simple matter. You can buy a network card which either you or a qualified technician can install inside your computer relatively easily. For laptops, you can buy an external component that connects via a USB port. Install the driver software for the card, and your computer is ready to accept a connection for the internet. All you need to do is find a hotspot.
