Setup

1. Driver Installation: Before inserting the DWL-650+ PC Card, install the necessary drivers from the provided installation CD or download the latest drivers from the official D-Link support website. Follow the on-screen instructions. Note: Some operating systems, particularly Windows XP, may require specific driver versions or updates to function correctly. Refer to D-Link's support resources for compatibility information.
2. Insert the PC Card: With your laptop powered on, carefully insert the DWL-650+ PC Card into an available CardBus slot until it clicks into place.
3. System Recognition: Your operating system should detect the new hardware and complete the driver installation process. If prompted, direct the system to the drivers you installed in step 1.
4. Configuration Utility: Once the card is recognized, launch the D-Link AirPlus configuration utility. This utility allows you to scan for available wireless networks, connect to them, and manage network profiles.
5. Connect to a Network: Use the utility to select your desired wireless network (SSID) and enter any required security keys (e.g., WEP key).

Important: Ensure your laptop's BIOS and operating system are up-to-date for optimal compatibility and performance. Disabling other network adapters temporarily during installation may prevent conflicts.

Operating

The DWL-650+ PC Card supports two primary operating modes:

• Infrastructure Mode: Connects your laptop to a wireless access point (router) to access the internet or a local network. This is the most common mode for home and office use.
• Ad-Hoc Mode: Allows direct connection between two or more wireless cards without an access point. This is useful for creating a small, temporary network for file sharing.

To manage your wireless connection:

1. Launch the Configuration Utility: Access the D-Link AirPlus utility from your system tray or Start Menu.
2. Scan for Networks: Use the utility to refresh the list of available wireless networks.
3. Connect/Disconnect: Select the desired network and click "Connect." To disconnect, select the active network and click "Disconnect."
4. Profile Management: The utility allows you to create and save detailed connectivity profiles for frequently accessed networks, simplifying future connections.
5. Security: Ensure WEP encryption is enabled and configured correctly if your wireless network requires it. The DWL-650+ supports 64, 128, and 256-bit WEP.

Note: The card may not automatically switch to a stronger signal from a different router if it is already connected to a weaker one. Manual intervention via the configuration utility may be required in such scenarios.

Maintenance

• Driver Updates: Periodically check the D-Link support website for updated drivers. Keeping your drivers current can improve performance, stability, and compatibility.
• Physical Care: Keep the PC Card clean and free from dust. Avoid exposing it to extreme temperatures or moisture. When not in use, store it in a protective case.
• Software Updates: Ensure your operating system and any related network management software are up-to-date.

Troubleshooting

Cannot install drivers or card not recognized:

Ensure you are using the correct drivers for your operating system. Download the latest drivers from the D-Link support website. Verify your laptop's CardBus slot is functioning correctly. Some users have reported success after updating their laptop's BIOS or using specific older driver versions for Windows XP.

Cannot connect to a wireless network:

Check that the wireless network (SSID) is broadcasting and that you have the correct security key (WEP). Ensure the card is in infrastructure mode if connecting to a router. Verify that other wireless devices can connect to the same network. Restart your laptop and the wireless router.

Unstable connection or poor signal strength:

Move closer to the wireless access point. Check for sources of interference (e.g., cordless phones, microwaves). Update your card's drivers and your router's firmware. The DWL-650+ may not automatically switch to a stronger signal from a different access point; manually select the desired access point using the configuration utility.

Slow data transfer rates:

Ensure you are connected to a D-Link AirPlus compatible access point to achieve the maximum 22 Mbps speed. Otherwise, speeds will be limited to standard 802.11b rates (up to 11 Mbps). Check for network congestion or interference.
