❍Prompt for the user name and password: Prompts for user name and password before you connect to the wireless network. The user name and password must first be set in the authentication server by the administrator.

❍Use the following user name and password: The user name and password must be first set in the authentication server by the administrator.

■User Name: This user name must match the user name that is set in the authentication server.

■Domain: Name of the domain on the authentication server. The server name identifies a domain or one of its sub-domains (for example, zeelans.com, where the server is blueberry.zeelans.com). NOTE: Contact your administrator to obtain the domain name.

■Password: This password must match the password that is set in the authentication server. The entered password characters display as asterisks.

■Confirm Password: Reenter the user password.

2.Click OK to save the settings and close the page. Server verification is not required.

Cisco Compatible Extensions, Version 4 (CCXv4)

To set up a client with EAP-FAST authentication with Cisco Compatible Extensions, version 4 (CCXv4):

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 Network (Infrastructure).

6.Click Next to open the Security Settings.

7.Network Authentication: Select WPA-Enterprise or WPA2-Enterprise.

8.Data Encryption: Select one of the following:

❍TKIP provides per-packet key mixing, a message integrity check and a rekeying mechanism.

❍AES-CCMP(Advanced Encryption Standard - Counter CBC-MAC Protocol) is used as the data encryption method whenever strong data protection is important. AES-CCMP is recommended.

9.Data Encryption: Select AES-CCMP.

10.Enable 802.1x: Selected.

11.Authentication Type: Select EAP-FASTto be used with this connection.

Step 1 of 3: EAP-FAST Provisioning

With CCXv4, EAP-FAST supports two modes for provisioning:

●Server-Authenticated Mode: Provisioning inside a server authenticated (TLS) tunnel.

●Server-Unauthenticated Mode: Provisioning inside an unauthenticated (TLS) tunnel.

NOTE: Server-Authenticated Mode provides significant security advantages over Server- Unauthenticated Mode even when EAP-MSCHAPv2 is being used as an inner method. This mode protects the EAP-MSCHAPv2 exchanges from potential Man-in-the-Middle attacks by verifying the server’s authenticity before exchanging MSCHAPv2. Therefore, Server-Authenticated Mode is preferred whenever it is possible. EAP-FAST peer must use Server-Authenticated Mode whenever a certificate or public key is available to authenticate the server and ensure the best security practices.

Provisioning of Protected Access Credentials (PAC):

EAP-FAST uses a PAC key to protect the user credentials that are exchanged. All EAP-FAST authenticators are identified by an authority identity (A-ID). The local authenticator sends its AID to an authenticating client, and the client checks its database for a matching AID. If the client does not recognize the AID, it requests a new PAC.

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.
