2.Select a Device to Device (ad hoc) network in the Wireless Networks list. Click Connect. The Intel PROSet/ Wireless software automatically detects the security settings for the wireless adapter.

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

3.If Data Encryption is required, you may select WEP. You are asked to select either a 64-bit or 128-bit encryption level Security Password (Encryption Key) and a Key Index. These values must match the various devices in your device to device (ad hoc) network, or data is not transferred.

NOTE: If you need to edit or change the wireless network settings, refer to Profile Management for more information.

To create a profile for a wireless network connection with WEP encryption:

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

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

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

4.Profile Name: Enter a descriptive profile name.

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

6.Click Next.

7.Click Enterprise Security to open the Security Settings.

8.Network Authentication: Open is selected (Default). Ad hoc networks only use Open authentication.

9.Data Encryption: Select WEP. WEP data encryption can be configured with 64- or 128-bit key.If the wireless device does not have the correct WEP key, the device is unable to transmit or decrypt data.

10.Encryption Level: Select 64- or 128-bit.

11.Wireless Security Password (Encryption Key): Enter the wireless network Password (WEP Key). The Password is the same value used by the wireless access point or router. Contact your administrator for this password.

●Pass phrase (64-bit):Enter five (5) alphanumeric characters, 0-9, a-z, or A-Z.

●Hex key (64-bit):Enter 10 hexadecimal characters, 0-9, A-F.

●Pass phrase (128-bit):Enter 13 alphanumeric characters, 0-9, a-z, or A-Z.

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

12.Key Index: Select 1, 2, 3, or 4. Up to four passwords may be specified by changing the Key Index.

To change the security settings:

1.Click Profiles on the Intel PROSet/Wireless main window. The network that you just connected to is listed in the Profiles list.

2.Select the wireless network.

3.Click Properties to open the Wireless Profile Properties General Settings. The Wireless Network Name (SSID) and Profile Name are already defined. Device to Device (ad hoc) is selected as the operating mode.

4.Click Next to access the Security Settings.

5.Click Enterprise Security.

6.Network Authentication: Open is the default. No authentication is used.

7.Data Encryption: WEP is selected. You can change the WEP key, key index or encryption level.

8.Click OK to return to the Profiles list after you have completed your changes.

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.
