Maybe You Already Have Wireless and Don't Know It?
More and more laptops and desktop computers are coming
pre-equipped with wireless networking devices -- it's so cheap
that they might as well put it in, to have another thing to list
in the system specifications. It is easy to tell if a desktop
computer has wireless enabled. Have a look at the rear panel for
a small antenna. If its there then you have wireless. Laptops a
much more difficult to diagnose.
If you're anything like me, though, you probably don't even know
how much memory your computers have, never mind whether any of
them came wireless-enabled. When you don't know what wireless
networking is, it's easy to ignore it in a computer's
specifications, and never take the time to set it up and get it
working. Here are some things to look for if you want to check
your computer's wireless capabilities.
Intel Centrino
If your laptop came with something called 'Intel Centrino mobile
technology', then it's good news for you! Computer manufacturers
seem a little bad at explaining what this technology is or does,
but it basically means that your laptop has wireless networking
built right in, without you needing to do a thing. It is a
marketing name for a combination of the Intel Pentium M
processor and Intel's Pro/Wireless card.
Your computer should have a 'Centrino' sticker on it somewhere
if it is Centrino enabled. If you think you might have taken the
sticker off, you can check the name of your processor by right
clicking the My Computer icon on your desktop (or in the Start
Menu) and choosing Properties from the menu that appears. Take a
look at what it says after the word 'Computer' on this screen.
If you're interested, Centrino technology also increases battery
life and allows computers to be smaller. Don't worry, though, if
you didn't buy a Centrino laptop -- as long as your laptop has a
free card slot, installing wireless on it will be no trouble.
Desktop Computers
If you're not sure whether your desktop computer has a wireless
connection, the easiest thing to do is to turn it around and
look at it. If a wireless connection is present, you should
usually be able to see a small aerial sticking out of the back
of the computer, towards the bottom.
If there's nothing there, then it's still possible that you have
a wireless device in the computer, especially if you bought
it
recently and you think you do. It's not a good idea to try to
open up your computer just to check something, though, so you
should probably try and figure it out using Windows.
Checking in Windows
Instead of fiddling around with your computer hardware to see
what you've got, you can check easily enough using Windows'
Device Manager. To use it, right click My Computer, and choose
Manage from that menu. Now click Device Manager.
You should see a list of all the different kinds of things you
can install on your computer. Take a look under 'Network
adapters'. Ignore anything that says '10/100' or 'Ethernet' --
they're normal network connections, but not wireless ones. If
there's anything else there, it could be a wireless device.
If you think you have a wireless device, but it has a yellow
warning sign next to its name in the Device Manager, you should
take a look at it to see what's wrong by double clicking its
name. Windows should tell you why the device is not working at
the moment, and may suggest that you go through its
troubleshooter program. Do that before you do anything else.
If it turns out to be a driver problem, you should insert the
drivers CD that came with your computer. Of course, as is always
the way, you probably won't be able to find that CD -- but don't
worry, you should be able to find drivers online. First, you
should look on the website of the computer's manufacturer, and
then you should try searching for the name that the wireless
device had in Device Manager.
Of course, you might find after all this that you don't have a
wireless device after all. Hard luck. It's better to figure that
out now than to buy wireless equipment and then realise you had
some already, though, isn't it? Of course, even if you did find
a wireless device in one of your computers, you probably still
need more. Don't worry either way -- they're getting cheaper all
the time!
