Components of a wireless LAN
To set up your Wireless network at home you need to have
the following:
Access point (router)
Access points (routers) are two-way transceivers that
broadcast data into the surrounding environment. Access
points act as a mediator between wired and wireless
network. Most routers have a built-in DSL modem that will
allow you access to a high speed DSL internet connection.
The ISP (Internet Service Provider) you have chosen
normally supplies a modem/router with the subscription to
their services. Read carefully the documentation supplied
with your Access point/router for detailed setup
instructions.
Network cable (RJ45)
A network cable (also called RJ45 cable) is used to connect
the host computer to the access point (see illustration
below); this type of cable may also be used to connect
peripheral devices to the access point.
Wireless adapter
Most computers feature a wireless module and Wi-Fi button
that turns the network connection on or off. You may also
turn your wireless network on or off, or control what is
shared over the network with the network management
options.
Warning
Using wireless devices while flying in aircraft may be prohibited.
Switch off all devices before boarding an aircraft; they may be
dangerous to the operation of the aircraft, disrupt
communications, and even be illegal. After take off, ask the cabin
crew if you may enable Wi-Fi.
