Intel Wireless LAN drivers for Windows 2000/2003/XP/Vista/W7 - v12.2.2.0

Don't leave home with them. Many OEMs are still shipping the older 10.x and 11.x revisions of this software, and are known to have bluescreen issues and other bugs that should be avoided.

You can easily install these drivers into Windows 7 by using the compatibility mode setting of "Vista" on the installation executables, or by simply pointing Device Manager to the directory you extract the archive to.

The amount of wireless chipsets supported by this driver pack is rather astounding:
Intel(R) WiMAX/WiFi Link 5350, Intel(R) WiMAX/WiFi Link 5150, Intel(R) WiFi Link 5300, Intel(R) WiFi Link 5100, Intel(R) Wireless WiFi Link 4965AGN, Intel(R) Wireless WiFi Link 4965AG_, Intel(R) PRO/Wireless 3945ABG Network Connection, Intel(R) PRO/Wireless 2915ABG Network Connection, Intel(R) PRO/Wireless 2200BG Network Connection
