Things to consider
when buying or choosing a home wireless networking
A secure wireless
network makes sharing files between computers and devices (like a printer or
phone) easy. WiFi lets you surf the internet using a modem and router, without
messy cables. We look at how Wi-Fi works and the gear you'll need.
What Is A Wireless Network?
A wireless network
connects multiple computers and devices (printers, phones, tablets etc.)
together, without using cables. The devices "talk" to each other
through a central hub called a router. This enables the computers and devices
to:
* Share files and documents.
* Connect multiple computers to the one
printer.
* Enjoy multi-player gaming.
* Load files from portable wireless
devices, such as an phones and tablets.
What Are The Benefits Of Wi-Fi?
Wireless networks
do away with messy cables. This leaves you free to wander around the house or
office, while staying connected. New computers have Wi-Fi technology built-in,
while older ones will require a USB adaptor.
Connect To The Internet
Most wireless
routers come with a modem built into them. This enables all devices connected
to the router to be simultaneously connected to the Internet.
Is It Hard To Set Up?
Not at all. The
latest generation of networking gear (routers) comes with easy-to-follow
wizards that guide you through the process. Simply plug in, follow the prompts
and you're away.
What Are the Standards?
Wireless
technology (Wi-Fi) is available in a range of standards. These refer to factors
such as the data transfer rate and the operating frequency. The standard you
choose ultimately affects your network's speed and its range (distance):
* The top standard today is 802.11n.
* This offers faster transfer rates and
more range than the previous 802.11g format.
Important Security Note!
If you do not take
the necessary security steps, your network will be left wide open to anyone
within range. They could gain access to files on your computers (this could
include banking details or passwords). They could also download illegal content
using your Internet account.
Some, but not all,
of the ways to secure your network include:
* Change the default administrator
passwords.
* Turn on the encryption to scramble the
messages sent over the wireless network.
* MAC (Media Access Control) restricts
network access to selected devices.
Equipments
needed for setup
1. Router:
The central device that communicates to all connected devices:
* Choose a router with built-in modem
for Internet access.
* Also look for built-in firewalls for
extra security.
* Ensure it supports the latest 802.11n
format.
2. Network cable: While wireless
does away with cables, they offer much faster ADSL transfer speeds, so it is
always good to have the option.
3. Wireless network adapter: This
is important if the laptop or desktop you want to connect doesn't have Wi-Fi
capabilities already built into it, or to upgrade your laptop Wi-Fi standards:
* It's important to match the adapter to
the standard of the router you're using.
* USB adapters simply plug in, rather
than being physically installed inside the computer.
* Network adaptors are backwards
compatible. This means an 802.11g device will work with an 802.11b device etc.
4. Wireless access point: Think
of this as a wireless extension cable to give you more range, so you can move
further away without the signal being too weak.
5. Extra range antenna: Makes
your router signals more powerful, for extra range.
6. Network printer: Connects to
the network so multiple computers can print from it.
7. Computer
Devices: Are machines that are readily to be connected to the network such
as PCs, Phones, Tablets etc.
8. Modem:
This is necessary if the router is not modem built-in.
Simple Home Wireless Network Choices
Router:
A router with an in-built modem will connect to the Internet.
Standards:
Aim for 802.11n.
Security:
Make sure you secure your Wi-Fi network to ensure your files are safe.
Optional Extras
More
range: Use a wireless access point or an extra-range antenna to
increase the range of the network.
Network
adapters: If your laptop doesn't have built-in Wi-Fi, you can buy a
network adapter.
