Connecting the Ethernet Adapter to Your Network
There are two network scenarios as below:
Also known as a peer-to-peer network, an ad-hoc network is
one that allows all workstations and computers in the network
to act as servers to all other users on the network.
Ad-hoc
Networking
Users on the network can share files, print to a shared printer,
and access the Internet with a shared modem. However, with
ad-hoc networking, users can only communicate with other
wireless LAN computers that are in the same wireless LAN
workgroup, and are within range.
Infrastructure networking differs from ad-hoc networking in
that it includes an access point. Unlike the ad-hoc structure
where users on the LAN contend the shared bandwidth, on
Infrastructure an infrastructure network, the access point can manage the
Networking
bandwidth to maximize bandwidth utilization.
Additionally, the access 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.
Infrastructure networking has the following advantages over
ad-hoc networking:
Extended range: each wireless LAN computer within the
range of the access point can communicate with other
wireless LAN computers within range of the access point.
Roaming: the access point enables a wireless LAN computer
to move through a building and still be connected to the LAN.
Wired to wireless LAN connectivity: the access point
bridges the gap between wireless LANs and their wired
counterparts.
In the next charter, you will be guided to how to connect the adapter to wireless LAN

The Wireless Navigator Utility is provided to allow user easily to configure the adapter
through any Windows-based PC. This section describes procedures for installing the
Wireless Navigator Utility to PC.
Note!
Note!
Please make sure that your PC already has TCP/IP protocol installed. If not, please
contact your administrator for details if you have problems of setting up this TCP/IP
protocol in your PC.

Medium: 3-4 nearby APs
High: 5 or more nearby APs
When connected in an infrastructure
or ad-hoc mode, a list of nearby APs
or peers is displayed at the bottom of
the Info screen. When you re-load
the web page, the list will be
updated.
WEP enabled: Allows you to enable
or disable Wired Equivalency Privacy
(WEP) for encryption, with either 64-
or 128-bit encryption.
WEP key length: Enables you to
choose either a 64- or 128-bit
encryption scheme. Be sure that
the adapter’s WEP key must be the
same as the AP’s, otherwise adapter

6. FAQ & Troubleshooting
This chapter provides solutions to problems usually encountered during the installation and
operation of the Wireless Access Point. Please refer to the following descriptions to solve
the problems. If you can’t find an answer here, please contact your dealer for further
advices.
Q1: My PC can’t locate the Wireless Ethernet adapter. How to check the
problem?
A: Please follow the procedures below:
„
„
Check if the Ethernet cable is well connected.
Check if the IP addresses of your PC and Wireless Ethernet adapter both are on
the same IP network. If not, you may use Wireless Navigator to set up adapter’s
IP address, or change your PC’s IP address.
Q2: My adapter cannot communicate with Wireless Access Point. How to
check the problem?
A: Please follow the procedures below:
„
Check if you can use Wireless Navigator utility to access to the adapter first. If not,
please go through the procedure of Q1.
„
„
Check if the adapter is set to Infrastructure correctly.
Check if the SSID of your adapter is the same as AP’s. If not, please set it the
same as the SSID of AP’s.
„
„
Check if the WEP is enabled either in your adapter or access point. If yes, please
make sure that your adapter and the Wireless Access Point both have the same
setting for WEP, such as the key tables must match.
At last, please check if radio interference is causing a problem; see if connection
is possible when close to the Wireless Access Point. Remember that the
connection range can be as short as 100 feet in poor environment.
Q3: The Wireless connection speed is very slow. How to improve the
problem?
A: The wireless system will connect at the highest possible speed, depending on the
distance and the environment condition. To obtain the highest possible connection speed,
you have to try to adjust the Ethernet adapter’s location and its antenna’s direction. If you
find the interference is the problem, changing to another channel may show the
23

GeoWave GW-EN11H Wireless Ethernet Adapter User's Manual
improvement.
Q4: Can I run an application from a remote computer over the wireless
network?
A: This will depend on whether or not the application is designed to be used over a network.
Consult the application’s user guide to determine if it supports operation over a network.
Q5: Can I play computer games with other members of the wireless network?
A: Yes, as long as the game supports multiple players over a LAN (local area network).
Refer to the game’s user guide for more information.
Q6: What is the IEEE 802.11b standard?
A: The IEEE 802.11b Wireless LAN standards subcommittee, which is formulating a
standard for the industry. The objective is to enable wireless LAN hardware from different
manufacturers to communicate.
Q7: What’s Ad-hoc?
A: An Ad-hoc wireless LAN is a group of computers, each with a WLAN adapter, connected
as an independent wireless LAN. Ad-hoc wireless LAN is applicable at a departmental scale
for a branch or SOHO operation.
Q8: What is Infrastructure?
A: An integrated wireless and wired LAN is called an Infrastructure configuration.
Infrastructure is applicable to enterprise scale for wireless access to central database, or
wireless application for mobile workers.
Q9: What is Roaming?
A: Roaming is the ability of a portable computer user to communicate continuously while
moving freely throughout an area greater than that covered by a single Wireless Network
Access Point. Before using the roaming function, the workstation must make sure that it is
the same SSID with the Wireless Access Point of dedicated coverage area.
Q10: What is Spread Spectrum?
A: Spread Spectrum technology is a wideband radio frequency technique developed by the
military for use in reliable, secure, mission-critical communications systems. It is designed
to trade off bandwidth efficiency for reliability, integrity, and security. In the other words,
more bandwidth is consumed than in the case of narrowband transmission, but the trade off
produces a signal that is, in effect, louder and thus easier to detect, provided that the
24

GeoWave GW-EN11H Wireless Ethernet Adapter User's Manual
receiver knows the parameters of the spread-spectrum signal being broadcast. If a receiver
is not turned to the right frequency, a spread-spectrum signal looks like background noise.
There are two main alternatives, Direct Sequence Spread Spectrum (DSSS) and Frequency
Hopping Spread Spectrum (FHSS).
Q11: What is WEP?
A: WEP is Wired Equivalent Privacy, a data privacy mechanism based on a 64-bit or 128-bit
as described in the IEEE 802.11 standard.
