Introduction
The MSI Wireless 11g Access Point AP54G is IEEE802.11g
compliant, and connects one or more wireless enabled comput-
ers to an Ethernet network or Cable/xDSL modem for high speed
connection, anywhere in your home or office.
The wireless access point’s high-gain antennas offer a range of
operation of up to 500 feet indoor, providing seamless roaming
throughout your LAN infrastructure. Advanced user authenti-
cation ensures a high level of security for wireless networking,
while easy-to-use web-based configuration tools ensure that you’ll
always be in control. Best of all, the wireless access point fea-
tures easy installation - your choice to be free-standing, wall- or
ceilingmounted.
With all these features come together in one compact, lightweight,
and power-efficient unit, you have the ultimate in flexible net-
working - the wireless access point.

2
>>> 1.2 How AP54G Works
Infrastructure Mode: Infrastructure networking differs from
Ad-hoc networking is that it includes an Access Point. The Ac-
cess Point enables users on a wireless LAN to access an existing
wired network, allowing wireless users to take advantage of the
wired networks resources, such as Internet, email, file transfer,
and printer sharing.
AP54G

timedia and streaming video/audio - even through walls, floors
and ceilings. You get high-speed networking without wires -
ideal for home office networking requirements.
Superior Antennas Design
One external dipole and one internal patch antennas provide
superior polarized reception and transmission for the best signal
quality.
Wi-Fi Compliant
This access point complies with IEEE802.11g standard and
Wi-Fi, allowing full interoperability with any Wi-Fi certified
wireless product.
Easy Installation
WDS repeater bridge mode support for easy network
deployment; in addition, the user-friendly web-based interface
and step-by-step Setup Wizard make the access point fast and
easy to install.

Power: a steady Blue light glows to indicate the power adapter
is connected.
LAN: the Green light glows when the access point is con-
nected to the network; it blinks to indicate the traffic through
this port.
WLAN: the Green light blinks to indicate the status of the
access point’s wireless networking*.
* The WLAN LED will blink
slowly when the firmware
failed. In this event, you have
to resume the firmware.

Hardware Installation
>>> 3.1 Installing Your Access Point
Positioning
The access point can be free-standing, wall- or ceiling-mounted
(refer to 3.2 Free-standing Installation and 3.3 Wall- or Ceiling-
mounted Installation). Before making the access point workable,
please note that the access point should be placed in a location
with the followings:
- Easy accessibility: you can conveniently connect the
access point to the xDSL/Cable Modem through the
Ethernet port.
- Easy LEDs observation: you may monitor the real-time
networking status and take instant measures as
problems arise.
- Maximum wireless coverage: to achieve the maximal
coverage, the access point should be placed at a high
level in position without obstacles and defiladed space.
No matter how you install the access point - in a wall-
mounted or free-standing fashion, remember the antenna
should always point vertically upward.
Connecting Cables
1. Plug the DC end of the power adapter into the
connector of the access point, and the AC end to the
wall outlet later.
2. For wired connection, connect the access point to the
LAN port.
Power Up
When the DC end of the power adapter is connected to the
access point, plugging the AC end of the power adapter to the
wall outlet will power up the system immediately.

12
>>> 3.2 Free-standing Installation
Unpack the package and
find the access point
with its stand.
Locate the mounting
holes on the rear side of
the access point and
align them to the hooks
of the stand.
The access point is hooked to
the stand. The free-standing
installation is completed.

>>> 3.3 Wall- or Ceiling-mounted Installation
Take out the AP54G and
screws.
Hammer the screws
partly into the wall (or
the ceiling) and then use
the screwdriver to screw
them half into the wall.*
The mounting distance
between screws is 5.5cm.
* An electric drill
may also do the job.

Tips on installing the access point
For maximum wireless coverage:
wall-mounted AP54G - antenna vertically upward;
free-standing AP54G - antenna vertically upward;
ceiling-mounted AP54G - antenna vertically downward.
