The Agere Wireless Mini PCI Card is a type of wireless network card designed to provide Wi-Fi connectivity to laptops or desktop computers. The "Mini PCI" refers to the form factor of the card, which is typically used in laptops or compact devices. Agere Systems (now part of LSI Corporation and later acquired by Avago Technologies) produced wireless network solutions, and the card would support wireless communication using Wi-Fi standards like 802.11b or 802.11g, depending on the model.

To use the Agere Wireless Mini PCI Card with a Windows computer, you need to install the correct Windows driver. The driver enables your computer to communicate with the wireless card, allowing you to connect to Wi-Fi networks.
