Overview

The Wireless LAN PC Card PCWA-C150S allows multiple computers to communicate and exchange data wirelessly. It supports two configuration modes: "Infrastructure Mode" (using an Access Point) and "Peer-to-Peer Mode" (direct computer-to-computer communication). The product conforms to the IEEE 802.11b standard.

Getting Started

The manual guides users through unpacking the PC Card, installing the Client Manager software and the driver software for Windows Me, Windows 2000, and Windows XP. It also covers starting the software and uninstalling it.

Software Setup

Instructions are provided for setting up the connection environment, checking communication status, and signal strength. It details how to connect to an Access Point, including entering encryption keys if Data Security is enabled.

Troubleshooting

A troubleshooting section addresses common issues such as the computer not detecting the PC Card, inability to access the Internet, slow transfer speeds, and error messages.

Troubleshooting and error codes

Symptom Cause/Remedy
Computer does not detect the Wireless LAN PC Card. The Wireless LAN PC Card may not be properly inserted into the PC Card slot of the computer.
→ Check that the Wireless LAN PC Card is inserted in the proper direction, then push it in as far as it will go.
Other computers on the wireless LAN are not displayed. You did not enter the password when Windows started.
→ Enter the user name and the password requested on Windows startup, then log onto the LAN.
The Windows network environment is not properly set up.
→ Check the Windows network settings. For details, see Windows Help.
No other computers are logged onto the wireless LAN.
Cannot access the Internet. The Access Point is not connected to the Internet.
→ Connect the Access Point to the Internet, as described in the documentation of the Access Point.
Wireless LAN PC Card is not inserted in the computer.
→ Insert the card, as described in "Inserting the Wireless LAN PC Card" on page 36.
Communication between the Access Point and the computer is not established.
→ Use Client Manager to check the communication status.
The Access Point is not properly configured.
→ Configure the Access Point according to its documentation.
The Access Point and the computer are too far apart.
→ Reposition the computer within 100 m (330 feet) of the Access Point, in direct line of sight.
Data transfer speed is slow. There is radio interference with another Access Point.
→ Try assigning another channel number to the Access Point.
There are too many clients logging on to the Access Point.
→ Try later.
Forgot the encryption key. → Return Access Point to factory default settings and then configure it again. For details on how to do this, see the documentation of the Access Point.
Transfer rate is 11 Mbps, but MPEG2 data do not transfer without interruption. 11 Mbps is a theoretical value. Under real-world conditions, transfer rate will normally be in the range of 4 - 5 Mbps. This is true for all IEEE 802.11b compliant systems. The bandwidth available with wireless communications may not be sufficient for high-volume streaming data such as MPEG2.
Communication fails although the computer is located within 100 m (330 feet) of the Access Point. The actual communication distance depends on various factors such as installation site conditions, presence of obstacles, etc.
→ Move the computer closer to the Access Point.
Link test results in many dropped messages. The Access Point and the computer are too far apart.
→ Move the computer closer to the Access Point.
File transfer is in progress on the network.
→ During transfer of large files, performance may temporarily drop. Repeat the test when the network is not being used for file transfer.
There is radio interference.
→ If there is another wireless station nearby using the same channel, try changing the channel number.
→ If a Bluetooth enabled wireless device is being used nearby, stop using it at the same time.
A microwave oven is being used nearby.
→ A microwave oven may also have an adverse effect on communication performance. Do not use it at the same time.
Cannot connect to the network. The Access Point and the computer are too far apart.
→ Move the computer closer to the Access Point.
Communication settings are incorrect.
→ Check the settings for Network Name, Data Security, Profile, etc.
An error message indicating a conflict between network components is displayed. Check the versions of related software and hardware, and obtain updates if required. To check the version, right-click the Client Manager icon on the taskbar, and select Help — Version Info from the submenu.
