Wireless Networks

Signal Quality	The signal quality icon bars indicate the quality of the transmit and receive signals between your
	wireless adapter and the nearest access point or computer in Device to Device (ad hoc) mode. The
	number of vertical green bars indicates the strength of the transmit and receive signals.
	The signal quality ranges from excellent to out of range. The following factors affect signal quality:
	● Signal quality decreases with distance and is affected by metal and concrete barriers.
	● Metal objects can reflect signals and cause interference.
	● Other electrical devices can cause interference.
Properties	Provides adapter connection status information. See Properties Button for information.
Wireless On (Off)	Switch the radio off and on. Refer to Turn Wireless On or Off for more information.
Help?	Provides help information for this page.
Close	Closes the Intel PROSet/Wireless main window.

The Wireless Networks list displays a list of wireless networks within range of the adapter.

Name	Description
	The signal strength of the wireless network access point or computer (Device to Device
	[ad hoc] mode). The signal strength icon bars indicate that the wireless network or
	computer is available for connection but is still not is associated with an access point or
	computer (Device to Device [ad hoc] mode).
Network Name	Network Name (SSID): The name of the network that the adapter is connected to.
	The Network Name SSID must be the same as the SSID of the access point.
Status	Notification that the adapter is connecting to the wireless network. Once connected, the
	status is changed to Connected.
	Profiles: Identifies a network in the Wireless Networks list that is connected and has a
	profile in the profiles list.
	The wireless network uses Network (infrastructure) mode.
	The wireless network uses Device to Device (ad hoc) mode.
	The wireless network uses Security encryption.
	The band frequency being used by the wireless network (802.11a, 802.11b, 802.11g).
	The wireless network is on the exclusion list or the profile is configured for manual
	connection.
Connect (Disconnect)	Click to connect to a wireless network. Once connected, the button changes to
	Disconnect.
Properties	Provides detailed information about the connected network and its access points. See
	Network Properties for information.
Refresh	Refreshes the list of available networks. If any new networks are available within the
	adapter range, the list is updated to show the new network name.

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.
