1 Introduction
1.1 Overview
Thank you for choosing RAVO 54GWireless Access Point. The
W54-AP is device that provides mobile wireless clients the
connectivity to a wired network. This enables the wireless clients to
access all available resources and peripherals on the wired
network. In addition, multiple Access Points can be installed to
extend the wireless service coverage area for seamless wireless
access.
With the support of new emerged 802.11g standard, the Access
Point provides data transfer of up to 54 Mbps, up to 5 times faster
than 802.11b. Since 802.11g operates on the same frequency of
2.4 GHz as 802.11b, it is backwards compatible with existing
802.11b devices. The benefit is that you can preserve the existing
802.11b infrastructure while migrating to the new screaming fast
802.11g.
In addition, this Access Point implements a built-in Web server for
easy configuration.
1.2 Package Contents

checklist below. If any of the items is missing, then contact the
dealer from whom the equipment was purchased.

1.3 Wireless Network Scenarios
An AP is used as a bridge linking the wireless station to a wired
LAN and thus creating an Infrastructure network. According to the
scale of your network, you can install a single AP or multiple APs to
create a roaming wireless network.
The simplest Infrastructure network is depicted as the figure below
where a group of wireless clients and an AP composes a Basic
Service Set (BSS). As this 54Mbps AP is 802.11g and 802.11b
compliant, it is capable of linking both the 802.11g and 802.11b
wireless clients to your wired network.
Figure 1-1 Connecting to a single AP
For larger area, you can also choose to implement multiple APs to
extend the wireless service coverage area for seamless wireless
access. A group of wireless clients and multiple APs using the
same SSID form an Extended Service Set (ESS). The figure below
shows a typical roaming wireless network within which each AP
operates in an independent channel. But all the APs use an
identical SSID and security settings (if enabled).
For the mobile clients that want to wander across the different APs
but maintain the network connectivity at all times, they must
operate in Infrastructure mode and use the same SSID and

security settings (if enabled) with the APs. If the APs are “open”,
that is, periodically broadcast their SSIDs to allow the wireless
clients to recognize their presence, then wireless clients can use
the special SSID “any” to associate with these “open” APs.

2.2 Hardware Connection
Choosing a Place for the Access Point
• Place the device close to the power outlet for the cable to
reach it easily.
• Locate an optimum location for the AP, usually at the
center of your wireless network to provide best coverage
for wireless stations.
• Adjust the direction of the antennas to enhance the
receiving sensitivity.
Connecting the AP
Follow the steps below to connect the related devices.
Step 1 Connecting the power adapter.
Connect the single DC output connector of the power
adapter to the power jack on the back of the AP. Then
connect the supplied power cord to the power adapter and
the other end to an AC outlet.
Step 2 Connecting to Ethernet network.
Attach one end of the Ethernet cable with RJ-45
connectors to your hub, switch or a PC’s Ethernet port,
and the other end to the LAN port of your AP.

3 Setting Up Ethernet / WLAN
Client
This chapter describes how to configure an Ethernet or wireless
station to access the AP’s built-in Web server for initial
configuration.
You can choose to access the AP’s Web interface via Ethernet or
wireless network. Whatever your choice, you must properly
configure the network settings of your PC to be on the same
subnet with the AP. As the AP is shipped with these defaults:
• IP address: 192.168.1.1
• Subnet mask: 255.255.255.0
Therefore, you should configure your PC’s TCP/IP settings to use a
static IP as below:
• IP address: 192.168.1.x (x is between 2 and 254)
• Subnet mask: 255.255.255.0
The ensuing sections will guide you through the static IP
configurations.
3.1 Setting up TCP/IP
Before proceeding, make sure your computer is equipped with
Ethernet network card or wireless adapter and has appropriate
network card driver and TCP/IP installed.
Note
If TCP/IP protocol is not installed on your PC, refer to Windows
documentations for installation instructions.

3.2 Additional Settings for Wireless Client
If you choose to access the router via a wireless client, also verify
the following:
1. Make sure your PC is equipped with 802.11g or 802.11b
wireless adapter and has appropriate WLAN card driver/utility
and TCP/IP installed.
2. Set the wireless adapter to use appropriate TCP/IP settings as
described in previous section.
3. Launch the wireless adapter’s provided utility and verify that
your wireless client is configured with these settings:
• Operation Mode: Infrastructure
• SSID: wirelesss
• Authentication: Open
• WEP Mode: Disabled
Note
If you only finished the wireless settings and didn’t configure the
wireless adapter’s TCP/IP settings, even your link status indicates a
successful connection with the AP, this connection applies to the
“physical” network layer only. Your wireless adapter cannot
communicate with the AP. Make sure to set the TCP/IP properties as
described in this previous section.
