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
An internal wireless adapter is normally already
installed in your computer. A button or controls in
Windows allow you to activate or deactivate the adapter.
