As long as you have all the hardware, you can quickly
set up any wireless network. Here is everything you need to know about the
hardware you need to have in place before you use Windows to configure the
wireless network.
There are two types of wireless networks: infrastructure and ad hoc.
The infrastructure network is most likely the type of wireless setup you have in
your home or office. It’s laid out similarly to a wirednetwork, but without
wires.

Hardware Needed for a Wireless Network |
The basic wireless, peer-to-peer network consists of these components:
Wireless router: The heart of the wireless network is the wireless router.
Like a wire-based network, the hub is a central location that all computers
connect to, providing the computers with network access.
The wireless hubs now available also serve as routers. Well, officially,
wireless hubs are gateways, not routers, but they're called routers. They’re
also called access points, so get used to that term as well.
Despite the nomenclature confusion, all you need to know is that the
hub/router/access point is a smart little beast that helps manage wireless
connections and also helps connect your wireless network to the Internet.
Wire-based connections: Almost every wireless router I’ve seen has one or
more standard, wire-based Ethernet port. One port is used to connect the router
to a broadband modem. Other Ethernet ports might be also available, allowing you
to connect standard wire-based networking to the wireless hub.
Wireless NIC: Your computer needs a wireless network information card, or
NIC, to talk with the wireless router. A laptop comes standard with a wireless
NIC, but for a desktop PC you have to get a wireless NIC as an option. It’s
installed internally as an expansion card, or you can use one of the various
plug-in USB wireless NICs.
That’s pretty much it for the infrastructure type of wireless network.
The ad hoc type of wireless network is basically a group of wireless
computers connected with each other. An ad hoc network has no central hub or
router. Instead, all its computers can directly access the other
computers’ files and shared resources. They may or may not have Internet access,
but that’s not the point of the ad hoc network.
One of the beauties of a wireless network is that you can mix in wired
components as needed. If you need more Ethernet ports, for example, simply add
a switch to the wireless router.
Despite the wireless nature of wireless networking, you still need an
Ethernet cable (a wire) to connect a wireless router to a broadband modem.
Another advantage of a wireless network is that it’s portable. It’s far
easier to pull up stakes with a wireless network than to pack up all the bits
and pieces of a wired network. If you live in an apartment, or just move around
a lot, a wireless setup a good option.
The term access point is often abbreviated AP. Don’t be puzzled when you see
the words wireless AP — it simply refers to the access point, not to the
Associated Press.
A wireless network is often called a WLAN, for wireless local-area
network.
A wireless network is also referred to by the term Wi-Fi. It stands
for wireless fidelity.
Ad hoc networks are often used by computer gamers to gather in a single
location to play games with each other.
