Wireless-G Access Point with Power Over Ethernet
Chapter 1: Introduction
Welcome
ThankyouforchoosingtheWireless-GAccessPointwithPowerOverEthernet. This Access Point willallowyou to
network wirelessly better than ever.
How does the Access Point do all of this? An access point allows for greater range and mobility within your
wireless network while also allowing you to connect the wireless network to a wired environment. In fact, the
Wireless-G Access Point with Power Over Ethernet can support communications on up to eight wireless
networks, using Virtual Local Area Network (VLAN) technology.
The Wireless-G Access Point with Power Over Ethernet also offers the convenience of Power over Ethernet (PoE)
capability, so it can receive data and power over a single Ethernet network cable.
But what does all of this mean?
Networks are useful tools for sharing computer resources. You can access one printer from different computers
and access data located on another computer's hard drive. Networks are even used for playing multiplayer video
games. So, networks are not only useful in homes and offices, they can also be fun.
PCs on a wired network create a LAN, or Local Area Network. They are connected with Ethernet cables, which is
why the network is called "wired".
PCs equipped with wireless cards and adapters can communicate without cumbersome cables. By sharing the
same wireless settings, within their transmission radius, they form a wireless network. This is sometimes called
a WLAN, or Wired Local Area Network. The Access Point bridges wireless networks of both 802.11g and 802.11b
standards and wired networks.
Use the instructions in this Guide to help you connect the Access Point, set it up, and configure it to bridge your
different networks. These instructions should be all you need to get the most out of the Access Point.
802.11b: a wireless networking standard that specifies a
maximum data transfer rate of 11Mbps and an operating
frequency of 2.4GHz.
802.11g: a wireless networking standard that specifies a
maximum data transfer rate of 54Mbps, an operating
frequency of 2.4GHz, and backward compatibility with
802.11b devices.
adapter: a device that adds network functionality to your
PC.
ethernet: network protocol that specifies how data is
placed on and retrieved from a common transmission
medium.
lan (local area network): the computers and networking
products that make up your local network.
network: a series of computers or devices connected
together.
poe (power over ethernet): a technology enabling an
Ethernet network cable to deliver both data and power.
access point: a device that allows wireless-equipped
computers and other devices to communicate with a wired
network. Also used to expand the range of a wireless
network.

Network Topology
Wireless-G Access Point with Power Over Ethernet
Chapter 2: Planning Your Wireless Network
Network Topology
A wireless network is a group of computers, each equipped with one wireless adapter. Computers in a wireless
network must be configured to share the same radio channel. Several PCs equipped with wireless cards or
adapters can communicate with one another to form an ad-hoc network.
Linksys wireless adapters also provide users access to a wired network when using an access point, such as the
Wireless-G Access Point with Power Over Ethernet, or wireless router. An integrated wireless and wired network
is called an infrastructure network. Each wireless PC in an infrastructure network can talk to any computer in a
wired network infrastructure via the access point or wireless router.
An infrastructure configuration extends the accessibility of a wireless PC to a wired network, and may double the
effectivewirelesstransmissionrange for two wireless adapter PCs. Since an access point is able to forward data
within a network, the effective transmission range in an infrastructure network may be doubled.
Roaming
Infrastructure mode also supports roaming capabilities for mobile users. Roaming means that you can move your
wireless PC within your network and the access points will pick up the wireless PC's signal, providing that they
both share the same channel and SSID.
Beforeusing the roaming capabilities, choosea feasible radio channel and optimum accesspointposition. Proper
access point positioning combined with a clear radio signal will greatly enhance performance.
infrastructure: a wireless network that is bridged to a wired
network via an access point.
ad-hoc: a group of wireless devices communicating directly
with each other (peer-to-peer) without the use of an access
point.
roaming: the ability to take a wireless device from one
access point's range to another without losing the
connection.
ssid: your wireless network's name

Network Layout
The Wireless-G Access Point with Power Over Ethernet has been designed for use with 802.11g and 802.11b
products. The Access Point is compatible with 802.11g and 802.11b adapters, such as the Notebook Adapters for
your laptop computers, PCI Adapters for your desktop PCs, and USB Adapters for when you want to enjoy USB
connectivity. These wireless products can also communicate with a 802.11g or 802.11b Wireless PrintServer.
To link your wired network with your wireless network, connect the Access Point’s Ethernet network port to any
switch or router. If you want to use Power Over Ethernet (POE), then connect the Access Point to any switch or
router that complies with the POE standard (802.3af)—or you can use a POE injector, such as the Linksys
WAPPOE or WAPPOE12.
With these, and many other, Linksys products, your networking options are limitless. Go to the Linksys website at
www.linksys.com for more information about wireless products.

Chapter 4: Connecting the Wireless-G Access Point with
Power Over Ethernet
Overview
This chapter explains how to connect the Access Point for setups.
Connections for Setup
1. Attach the Access Point’s antenna.
2. Connect your Ethernet network cable to your network router or switch. Then connect the other end of the
network cable to the Access Point’s Ethernet port.
3. If you are using Power Over Ethernet (POE), proceed to the following section, “Placement Options.”
If you are not using POE, then connect the included power adapter to the Access Point’s Power port. Then
plug the power adapter into an electrical outlet. The LEDs on the front panel will light up as soon as the
Access Point’s powers on.
Proceed to the following section, “Placement Options.”

Figure 4-2: Connect the Power
NOTE: The Bridge features Power Over
Ethernet (POE) support. POE technology allows
aPOE adapter (also known as apowerinjector,
power hub, or inline power device) to supply
data and power to an Ethernet device using a
single Ethernet network cable. To use the
Bridge’s POE feature, follow the instructions
for your specific POE device.

Placement Options
Wireless-G Access Point with Power Over Ethernet
Placement Options
There are three ways to place the Access Point. The first way is to place it horizontally on a surface, so it sits on
its four rubber feet. The second way is to stand the Access Point vertically on a surface. The third way is to mount
it on a wall. The stand and wall-mount options are explained in further detail below.
Stand Option
1. Near the Access Point’s bottom panel are two rubber feet and two rubber inserts. Remove them to expose the
stand slots you want to use.
2. The Access Point includes four triangular stands. With its rubber pad facing the bottom, insert a stand into a
slot, and push the stand upward until the stand snaps into place.
Repeat this step with the other stands.
Now that the hardware installation is complete, proceed to “Chapter 5: Setting Up the Wireless-G Access
Point with Power Over Ethernet,” for directions on how to configure the Access Point.
Wall-Mount Option
1. On one of the Access Point’s side panels are four rubber feet. Remove four adjacent feet to expose the wall-
mount slots you want to use. The distance between two adjacent slots is 145 mm (5.7 inches).
2. Determine where you want to mount the Access Point.
3. Drill four holes into the wall. Make sure adjacent holes are 145 mm (5.7 inches) apart.
4. Insert a screw into each hole, and leave 5 mm (0.2 inches) of its head exposed.
5. Maneuver the Router so the wall-mount slots line up with the four screws.
6. Place the wall-mount slots over the screws and slide the Access Point down until the screws fit snugly into
the wall-mount slots.
Now that the hardware installation is complete, proceed to “Chapter 5: Setting Up the Wireless-G Access
Point with Power Over Ethernet,” for directions on how to configure the Access Point.
