Introduction
This chapter introduces the NETGEAR 54 Mbps Wireless Access Point WG602 v3. Minimal
prerequisites for installation are presented in “System Requirements” on page 2-3.
About the 54 Mbps Wireless Access Point WG602 v3
The 54 Mbps Wireless Access Point WG602 v3 is the basic building block of a wireless LAN
infrastructure. It provides connectivity between wired Ethernet networks and radio-equipped
wireless notebook systems, desktop systems, print servers, and other devices.
The WG602 v3 provides wireless connectivity to multiple wireless network devices within a fixed
range or area of coverage, interacting with a wireless network interface card (NIC) via an antenna.
Typically, an in-doors access point provides a maximum connectivity area with about a 300 foot
radius. The 54 Mbps Wireless Access Point WG602 v3 can support a small group of users in a
range of several hundred feet. Most access points are rated for up to 32 users simultaneously.
The auto-sensing capability of the 54 Mbps Wireless Access Point WG602 v3 allows packet
transmission at up to 54 Mbps, or at reduced speeds to compensate for distance or electromagnetic
noise interference.
Support for Standards
The following standards and conventions are supported:
• Standards Compliant. The WG602 v3 Access Point complies with the IEEE 802.11g
(DSSS).
• WEP support. Support for WEP is included. Both 64-bit and 128-bit keys are supported.

You need to prepare these three things before you can establish a connection through your wireless
access point:
• A location for the WG602 v3 that conforms to the guidelines below.
• A device such as a hub, switch, router, or Cable/DSL gateway.
• One or more computers with properly configured 802.11b or 802.11g wireless adapters.
Observing Placement and Range Guidelines
Note: Indoors, computers can connect over wireless networks at ranges of several
hundred feet or more. This distance can allow for others outside your area to access your
network. It is important to take appropriate steps to secure your network from
unauthorized access. The WG602 v3 Access Point provides highly effective security
features which are covered in detail in this chapter. Deploy the security features
appropriate to your needs.
The operating distance or range of your wireless connection can vary significantly bas ed on the
physical placement of the wireless access point. The latency, data throughput performance, and
notebook power consumption of wireless adapters also vary depending on your configuration
choices.
Note: Failure to follow these guidelines can result in significant performance
degradation or inability to wirelessly connect to the WG602 v3.

User’s Guide for the WG602 v3 54 Mbps Wireless Access Point
For best results, place your wireless access point:
• Near the center of the area in which your PCs will operate.
• In an elevated location such as a high shelf where the wirelessly connected PCs have
line-of-sight access (even if through walls).
• Away from sources of interference, such as PCs, microwaves, and 2.4 GHz cordless phones.
• Away from large metal surfaces.
• If using multiple access points, it is better if adjacent access points use different
radio frequency
Channels to reduce interference. The recommended Channel spacing between adjacent access
points is 5 Channels (for example, use Channels 1 and 6, or 6 and 11).
The time it takes to establish a wireless connection can vary depending on both your security
settings and placement.

Understanding WG602 v3 Wireless Security Options
Unlike wired network data, your wireless data transmissions can be received well beyond your
walls by anyone with a compatible adapter. For this reason, use the security features of your
wireless equipment. The WG602 v3 Access Point provides highly effective security features
which are covered in detail in this chapter. Deploy the security features appropriate to your needs.

3) WEP: Secure but some vulnerabilities
4) WPA: Very strong security
Figure 3-1: WG602 v3 wireless data security options
There are several ways you can enhance the security of your wireless network:
• Restrict Access Based on MAC Address. You can restrict access to only trusted PCs so that
unknown PCs cannot wirelessly connect to the WG602 v3. MAC address filtering adds an
obstacle against unwanted access to your network, but the data broadcast over the wireless link
is fully exposed.
• Turn Off the Broadcast of the Wireless Network Name (SSID). If you disable broadcast of
the SSID, only devices that have the correct SSID can connect. This nullifies the wireless
network ‘discovery’ feature of some products such as Windows XP, but the data is still fully
exposed to a determined snoop using specialized test equipment like wireless sniffers.
• Use WEP. Wired Equivalent Privacy (WEP) data encryption provides data security. WEP
Shared Key authentication and WEP data encryption will block an eavesdropper but because
the keys are static, a determined snoop can learn the keys in less than a day of eavesdropping.
• Use WPA-PSK. Wi-Fi Protected Access (WPA) data encryption provides data security.
WPA-PSK will block eavesdropping. Because this is a new standard, wireless device driver
and software availability may be limited. However, WPA is not available in bridge mode.

Installing the 54 Mbps Wireless Access Point WG602 v3
Follow the instructions below to set up and test basic wireless connectivity. Once you have
established basic wireless connectivity, you can enable security settings and configure the
advanced wireless functions.
Before installing the 54 Mbps Wireless Access Point WG602 v3, you should make sure that your
Ethernet network is up and working. You will be connecting the access point to the Ethernet
network so that computers with 802.11b or 802.11g wireless adapters will be able to communicate
with computers on the Ethernet network. In order for this to work correctly, verify that you have
met all of the system requirements, shown on page 2-3.
1SET UP THE WG602 V3 ACCESS POINT
Tip: Before mounting the WG602 v3 in a high location, first set up and test the WG602 v3 to
verify wireless network connectivity.
a. Prepare a PC with an Ethernet adapter. If this PC is already part of your network, record its
TCP/IP configuration settings.
b. Configure the PC with a static IP address of 192.168.0.210 and 255.255.255.0 for the
Subnet Mask.

How to Log in Using the Default IP Address of the WG602 v3
1. 192.168.0.227 is the default IP address of your access point. However, the WG602 v3 is also
set, by default, to be a DHCP client. So, if the WG602 v3 has not yet been installed, and there
is no DHCP server on the network, you can log in to the WG602 v3 using its default IP
address. Otherwise, you should use either the NetBIOS login described in “How to Log In to
the WG602 v3 Using Its Default NetBIOS Name” on page 3-9 or the procedure described in
“Set up the WG602 v3 Access Point” on page 3-4” which uses a static IP configuration.
Note: The computer you are using to connect to the WG602 v3 should be configured with an
IP address that starts with 192.168.0.x and a Subnet Mask of 255.255.255.0.
2. Open a Web browser such as Internet Explorer or Netscape Navigator.
3. Connect to the WG602 v3 by entering its default address of http://192.168.0.227 into your
browser.
