Hex key (128-bit):Enter 26 hexadecimal characters, 0-9, A-F.

With 802.11, a wireless station can be configured with up to four keys (the key index values are 1, 2, 3, and 4). When an access point or a wireless station transmits an encrypted message that uses a key stored in a specific key index, the transmitted message indicates the key index that was used to encrypt the message body. The receiving access point or wireless station can then retrieve the key that is stored at the key index and use it to decode the encrypted message body.

Personal Security: Configure Profiles for Device to Device (Ad Hoc) Networks

Set up a Client with Open Authentication and No Data Encryption (None)

In device to device mode, also called ad hoc mode, wireless computers send information directly to other wireless computers. You can use ad hoc mode to network multiple computers in a home or small office, or to set up a temporary wireless network for a meeting.

On the Intel(R) PROSet/Wireless main window, select one of the following methods to connect to a device to device network:

●Double-click a ad hoc network in the Wireless Networks list.

●Select a network in the Wireless Networks list. Click Connect. The Intel PROSet/Wireless software automatically detects the security settings for the wireless adapter.

●Create a device to device (ad hoc) network profile as described below.

NOTE: Device to Device (ad hoc) networks are identified with a notebook image () in the Wireless Networks and Profiles list.

To create a profile for a wireless network connection with no encryption:

1.Click Profiles on the Intel PROSet/Wireless main window.

2.On the Profile page, click Add to open the Create Wireless Profile General Settings.

3.Profile Name: Enter a descriptive profile name.

4.Wireless Network Name (SSID): Enter the network identifier.

5.Operating Mode: Click Device to Device (ad hoc).

6.Click Next.

7.Click Personal Security to open the Security Settings.

8.Data Encryption: The default setting is None, which indicates that there is no security on this wireless network.

9.Click OK. The profile is added to the Profiles list and connects to the wireless network.

Set up a Client with WEP 64-bit or WEP 128-bit Data Encryption

When WEP data encryption is enabled, a network key or password is used for encryption.

You must enter the key and specify the length (64- or 128-bit) and key index (the location that a specific key is stored). The more complex the key (mixed letters and numbers), the more secure the key.

3945ABG specifications

The Intel 3945ABG is a wireless networking adapter that played a significant role in advancing wireless connectivity in laptops and portable devices. Introduced in the mid-2000s, this adapter is notable for its dual-band capabilities and compliance with the IEEE 802.11 a/b/g standards. It supports both 2.4 GHz and 5 GHz frequency bands, enabling users to connect to a variety of wireless networks while offering improved performance and flexibility.

One of the standout features of the Intel 3945ABG is its support for MIMO technology, which stands for Multiple Input Multiple Output. This innovative technology enhances data transmission rates and increases the range of wireless connections by utilizing multiple antennas for sending and receiving data. MIMO allows the adapter to operate more efficiently in environments with obstacles, such as walls or furniture, making it an ideal choice for users who need reliable connectivity in varied settings.

The Intel 3945ABG adapter also includes Wi-Fi Protected Access (WPA) and WPA2 security protocols, ensuring that data transmitted over the wireless network remains secure. This is especially important in a time when wireless networks became progressively more vulnerable to unauthorized access and data breaches. The adapter's compatibility with these security standards aids users in establishing secure communications, whether for casual web browsing or sensitive tasks.

In terms of performance, the Intel 3945ABG offers maximum theoretical speeds of up to 54 Mbps in the 802.11a and 802.11g modes, while maintaining lower speeds in the 802.11b mode (up to 11 Mbps). In practical use, this means that users can achieve high data transfer rates in optimal conditions, making it suitable for video streaming, online gaming, and large file downloads.

The Intel 3945ABG also integrates seamlessly with Intel's Centrino mobile technology, which enhances power efficiency and optimizes the overall performance of a laptop. This synergy not only extends battery life but also provides a smooth user experience, as it allows the adapter to effectively manage network resources and maintain a stable connection.

In summary, the Intel 3945ABG wireless adapter is characterized by its dual-band support, MIMO technology, robust security features, and integration with Intel's Centrino technology. While it may now be considered outdated by modern standards, it served as an important stepping stone in the evolution of wireless networking technology and continues to be remembered for its contributions to mobile connectivity.
