Left Side Primary and Right Side Secondary Detachable Antenna
The ME103 provides two detachable antenna. The one on the left is the primary, and the one on
the right is the secondary. See
“Understanding Advanced Wireless Settings” on page 5-8
and
“Antenna Installation” on page 5-13
for important information about configuring and
positioning the antenna to best take advantage of diversity and range capabilities of the ME103.
Restore to Factory Defaults Button
The restore to default button located between the Ethernet RJ-45 connector and the power
socket restores the ME103 to the factory default settings.
RJ-45 Ethernet Port
Use the ME103 Ethernet RJ-45 port to connect to an Ethernet LAN through a device such as a
hub, switch, or router.
Power Socket
This socket connects to the ME103 power adapter.

Chapter 3
Basic Installation and Configuration
This chapter describes how to set up your ME103 802.11b ProSafe Wireless Access Point for
wireless connectivity to your LAN. This basic configuration will enable computers with 802.11b
or 802.11g wireless adapters to do such things as connect to the Internet, or access printers and
files on your LAN.
You need to prepare these three things before you can establish a connection through your wireless
access point:
•
A location for the ME103 that conforms to the
Observing Placement and Range Guidelines
below.
•
The wireless access point connected to your LAN through 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
The operating distance or range of your wireless connection can vary significantly based 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:
Indoors, computers can connect over 802.11b 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 ME103 Access Point provides highly effective security
features which are covered in detail in
Chapter 3, “Configuring Your Wireless Network
.
Deploy the security features appropriate to your needs.

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. WEP connections can take slightly longer to establish. Also, WEP
encryption can consume more battery power on a notebook PC.
Cabling Requirements
The ME103 Access Point connects to your LAN via twisted-pair Category 5 Ethernet cable with
RJ-45 connectors.
Note:
Failure to follow these guidelines can result in significant performance
degradation or inability to wirelessly connect to the ME103. For complete performance
specifications, see
Appendix A, “Specifications”
.
Note:
The power adapter and cord shipped with the ME103 limits the distance from an
AC outlet. To overcome this, consider using NETGEAR’s POE101 Power Over
Ethernet Adapter with a Cat 5 Ethernet cable like the one included with your ME103.
This adapter sends DC power through an Ethernet cable to enable you to power an
access point in a remote location up to 328 feet away.

When you first receive your ME103, the default factory settings will be set as shown below. You
can restore these defaults with the Factory Default Restore switch on the rear panel — see

Understanding ME103 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 ME103 Access Point provides highly effective security features which
are covered in detail in this chapter. Deploy the security features appropriate to your needs.
Figure 3-1: ME103 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 ME103. 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 all but the most determined
eavesdropper.
•
Implement 802.1x.
IEEE 802.1x provides very strong security. Although it can use the same
data encryption scheme as WEP, it enables stronger authentication as well as the ability to
dynamically vary the encryption keys.
1) Open System: Easy but no security
2) MAC Access List: No data security
3) WEP:
Security but some vulnerabilities
