Note: Versions of the Windows OS prior to Windows XP require "Client Manager" software. Windows XP has the Client Manager function built-in.

This driver is installed on your machine at the time of its manufacture.

Note: If you installed a Microsoft Update and choose a "Driver Update" for your Wi-Fi card, and the wireless connection stopped working, re-install the Toshiba driver, or in the case of Windows XP, choose Roll Back Driver in the Control Panel entry for  the Wi-Fi card, as follows: Start, Control Panel, System, Hardware tab, Device Manager, Network Adapters, double-click Toshiba Mini-PCI wireless adapter, Driver tab, Roll Back Driver.
