Introduction to networking
The most common way to set up a wireless Ethernet network is Dynamic Host Control
Protocol (DHCP) using a wireless access point router.
A DHCP network configuration uses
an access point router to automatically assign IP addresses to each computer or network
device.
Example access point router wireless Ethernet network
By using an access point , you can join a wireless Ethernet network and access a wired
Ethernet network.
The following is an example of an access point wireless Ethernet network that shows how
an access point also lets you access the Internet. The network is made up of an access point,
a cable or DSL modem, and your computers. The access point is the central control point
for the network. Attached to the access point is the cable or DSL modem that provides
access to the Internet. Each of the computers or Ethernet-ready devices communicate with
the access point using radio waves. If your computer does not have a built-in wireless
Ethernet emitter, you need to add a wireless PCI card (desktop), PC card (notebook), or
USB adapter.

Important
The speed of a wireless network is related to signal strength. Signal
strength is affected by the distance between your wireless network
devices, by radio interference, and by interference from natural
obstructions such as walls, floors, and doors.
