This is the essential item that connects you to the Internet with the built in modem. The router allows more than one PC to connect wirelessly to the modem at the same time.

Wireless routers allow you to have several computers/laptops connected to it wirelessly, and also wired. Take a look at the Freeola Shop for an excellent selection of wireless equipment.

Wireless network adapters connect your computer to your wireless modem/router.

For a desktop computer, you can buy a USB wireless network adapter which you simply plug into a USB port on your computer or a PCI card version instead which needs to be installed internally.

USB versions are much easier to install, however, internal PCI cards are better suited for office users as you won't need to worry about running out of USB ports.

Most modern laptops usually have a built-in wireless card. You can check whether your laptop has one on the original documentation when the laptop was first purchased. If your laptop doesn't already have a wireless capabilities built-in, you can use either a USB wireless adaptor or a PCMCIA card. The latter item is a tidier option as it is based inside your laptop (don't worry you don't have to undo the case to install this!)
