Wired Network Working Into Wireless Access Points
Let's dive into something a little more complex. What if you
have a wired network already, and you're quite happy with the
way it performs -- you see no point in dismantling it and making
it wireless when it works fine as it is. You've got this laptop,
though, that you'd really like to use wirelessly. Basically,
what you want to do is make a wireless connection to a wired
network. This is often referred to as a network bridge.
As luck would have it, there's a very easy way to do exactly
what you want. It's called a wireless access point.
Partly Wireless
If you've got a lot of computers (on an office network, for
example) and you can't switch them all over to wireless
networking at once, installing a wireless router is a good way
of doing it bit-by-bit. Once the router is part of the network,
you could just remove one network wire per day or per week,
replacing it with a wireless connection.
Hardware and Software Requirements
There are two kinds of wireless access points: software and
hardware ones. Wireless access point software runs on one of the
computers on the wired network, and lets wireless devices
connect to the network through that computer (the computer must
obviously be wireless-enabled).
You can get wireless access software easily -- doing a web
search will give you plenty of choices. Look for one that's open
source, as you will be able to download it straightaway for free
without breaking any laws. Unfortunately, though, the wireless
devices will only be connected to the network while the computer
in question is turned on and connected itself.
Hardware access points, on the other hand, are standalone
devices that can be plugged in anywhere on the network -- you
can either buy a dedicated access point, or convert an old
computer to act as one and do nothing else. They connect to the
wired network just as a normal computer would, except that they
offer access to the network to any wireless receivers within
range.
You can leave hardware access points connected to your network
and turned on all the time, if you want. An advantage of
dedicated devices is that they generally have a greater range,
letting you use your wireless devices further away from the
access point than
you could with a software access point.
Dedicated devices can be expensive, though -- prices are roughly
similar to wireless routers.
How Wireless Access Points Work
An access point sends requests for data on behalf of the
wireless devices connected to it. In this way, it works a lot
like a wireless router: basically, a wireless access point is to
a wired LAN as a wireless router is to the Internet. The
difference, though, is that the devices connected through an
access point actually become part of the LAN -- other computers
on the LAN won't distinguish between the wired computers and the
wireless ones.
This is powerful, as it gives you the capability to dynamically
extend your wired LAN, without wires. In theory, there shouldn't
be anything you can currently do over your wired network that
you won't be able to do over the wireless extension to it.
Configuring a Wireless Access Point
You can usually configure a wireless access point as easily as
plugging it into a connection to your network, using the cable
that should be included. Your network should see the access
point and give it a networking (IP) address automatically. If
you need to do any more configuration on your access point --
for example, turning on wireless encryption -- then you'll need
to open your access point's settings.
You can do this by going to the router's IP address in your web
browser. If you're not sure how to do this, refer to your access
point's manual (you might have better luck reading the online
version, which will be updated with the latest problems people
are having). While you're playing with your access point's
settings, you might find it worth disabling DHCP (dynamic
network addressing) and giving your access point a static
address instead. This helps to keep your wired network more
stable.
