A large-scale WLAN, such as a corporate or public WLAN, typically uses wireless access points that can
accommodate a large number of computers and accessories and can separate critical network functions.
●
A home or small office WLAN typically uses a wireless router, which allows several wireless and wired
computers to share an Internet connection, a printer, and files without requiring additional pieces of
hardware or software.
To use the WLAN device in your computer, you must connect to a WLAN infrastructure (provided through a
service provider or a public or corporate network).
Using an Internet service provider
When you are setting up Internet access in your home, you must establish an account with an Internet service
provider (ISP). To purchase Internet service and a modem, contact a local ISP. The ISP will help set up the
modem, install a network cable to connect your wireless computer to the modem, and test the Internet
service.
NOTE:
Your ISP will give you a user ID and a password to use for Internet access. Record this information
and store it in a safe place.
Setting up a WLAN
To set up a WLAN and connect to the Internet, you need the following equipment:
●
A broadband modem (either DSL or cable) (1) and high-speed Internet service purchased from an
Internet service provider
●
A wireless router (2) (purchased separately)
●
A wireless computer (3)
NOTE:
Some modems have a built-in wireless router. Check with your ISP to determine what type of modem
you have.
The illustration below shows an example of a wireless network installation that is connected to the Internet.
As your network grows, additional wireless and wired computers can be connected to the network to access
the Internet.
For help in setting up your WLAN, see the information provided by your router manufacturer or your ISP.
Configuring a wireless router
For help in setting up a WLAN, see the information provided by your router manufacturer or your ISP.
NOTE:
It is recommended that you initially connect your new wireless computer to the router by using the
network cable provided with the router. When the computer successfully connects to the Internet, disconnect
the cable, and access the Internet through your wireless network.
