Authentication failed because timer expired

Authentication failed because the authentication timer expired while this mobile station was authenticating. A rogue access point or a problem with the RADIUS server could have been the reason for the problem.

Recommended action:

If a rogue access point is suspected, consider adding this access point to the excluded access point list to prevent the wireless adapter from connecting to this access point in the future.

If a rogue access point is not suspected, click the profile in the profile list. Click Connect to associate with the network and attempt to authenticate with the server.

Smart Card was unexpectedly removed

This error occurred because the Smart Card was unexpectedly removed.

Use the following a steps to resolve this error:

1.Insert the Smart Card.

2.Select the 802.1x EAP-SIM authentication profile.

3.Click Connect to try to associate with the network.

Disconnection from an Access Point

The following error messages display when the wireless adapter is disconnected from the network access point.

Disconnect from access point due to failed associations.

Disconnect from access point due to authentication failures.

Disconnect from access point due to TKIP Michael Integrity check failure.

Disconnect from access point due to Class 2 frame non-authentication failure.

Disconnect from access point due to Class 3 frame non-association failure.

Disconnect from access point due to reassociation failure.

Disconnect from access point due to Information Element failure.

Disconnect from access point due to EAPOL-Key protocol four-way handshake failure.

Disconnect from access point due to 802.1x authentication failure.

Recommended action: Select the profile. Click Connect and try to associate with the network.

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.
