provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses, and can radiate radio frequency
energy and, if not installed and used in accordance with the instructions, may
cause harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If this
equipment does cause harmful interference to radio or television reception,
which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the following
measures:
1. Reorient or relocate the receiving antenna.
2. Increase the separation between the equipment and receiver.
3. Connect the equipment into an outlet on a circuit different from that to

By using radio frequency (RF) technology, the need for wired
connections is minimized while WLANs transmit and receive data
over the air. Therefore, WLANs combine data connectivity and
user mobility through simplified configuration, enabling movable
LANs.
AOpen AOI-701U wireless LAN PC adapters allow notebook
users to access shared information without looking for a place to
plug in. It offers mobility and flexibility to the LAN users. In
addition to the easy installation, AOI-701U is compatible with

NSTALLATION
Overview
Please follow these to establish your wireless network connection:
1. Install Access Point (AOI-706U) first, if the
infrastructure network is required.
2. Install the Driver CD.
3. Install the USB Wireless LAN Adapter (AOI-702U).
4. Install the network protocol(S) which is required for
networking communication on your network. (Most likely
you will need the TCP/IP protocol.)

VERSION.
STATUS (see figure 2)
It shows the information of the linkage between this
wireless pc adapter and the wireless access point.
Click the CHANGE button to change the set ups, and click the
SUMIT button after the configuration has been changed.
Operation Mode
The Operation Mode setting determines the structure of your
wireless network. The default is Infrastructure mode.
AOpen Wireless PC Adapter
Ad Hoc: The Ad-Hoc mode is for a simple peer-to peer
network. ( with no Access Point needed)
Infrastructure: The infrastructure mode allows wireless
users to be able to access to the wired (existed) network by
using an Access Point. With Multiple access points, they
provide roaming, which extend the coverage of the wireless
network.
Channel
It specifies the channel used in wireless communication and should
be set to the same channel with other wireless nodes in the same
wireless network. The default channel is channel 6.
SSID (Service Set Identifier)
SSID is the unique name shared among all nodes in a wireless
network. The SSID must be the same for all the nodes on the
network, and is case sensitive. The default SSID is aopen.
TX Rate: This is the current transfer rate for the network card. It
should set to Fully Automatic to get the optimal performance
State
State is to display the current state of the linkage.
It shows the BSS ID of the associated Access Point which wireless
connects to the adapter. The state is showing “Scanning” when the
adapter is searching for an available access point. Sometimes it is
because the adapter can not detect the SSID for an access point
within the range. An error message may be displayed when the
driver failed to initialize.
Signal Strength
It is active only when the node is in Infrastructure Mode. Here
displays the signal strength of the connection.

Link Quality
This is active only when it is in Infrastructure Mode. Here
displays the quality of the linkage between the adapter and the
Access Point.
Link Quality is a measurement of receiving and transmissions
errors. It will start looking for a better Access Point when the Link
Quality indication poor connection.
MAC Address
This unique 48-bit Media Access Control address is known as the
station identifier.
STATISTICS
It shows the total amount of packets which have been
received or transmitted by the adapter.
SITE SURVEY
It shows all the Access Points nearby when the
Infrastructure mode is chose, or all the nearby wireless
adapters when it is in the Ad Hoc mode.

ENCRYPTION
Figure 5 ENCRYPTION tab
An additional security measurement may be desired on protecting
your wireless network. This can be achieved by applying WEP
(Wired Equivalent Privacy) encryption. WEP uses a combination
of 64bit and 128bit keys to encrypt every data transmission.
Encryption (WEP)
It can be set to Disable, 64 Bit, and 128 Bit. Once enable the WEP,
you would create an encryption key. All the nodes in the same
wireless network need to present the identical key for the
communication.
Key 1 – Key 4
The Keys can be entered manually in these four fields and restored.
Default Tx Key
You may chose Key 1 to Key 4 as your default key.
Authentication Type
It is only used for WEP only. You may choose between Open
System or Shared Key.
Shared Key is when both sender and receiver share a secret
key.
Open System is when both sender and receiver do not
share a secret key. It prevents the eavesdropping if the
secret key is discovered.
ADVANCED
Figure 6 ADVANCED tab
It allows you to set the Preamble Type, Fragmentation Threshold
and RTS/CTS Threshold.
Preamble Type
It should be set to Long for a “noisy” network environment, or
Short for a clear network environment.
Fragmentation Threshold
The lower value of the fragmentation threshold will increase the

devotion to recovering packet errors, however at the same time, it
will also decrease the network performance.
RTS/CTS Threshold
The higher value of RTS/CTS threshold will increase better traffic
coordination of the wireless network.
