Via Toshiba’s support site. Satellite L305-S5907 Drivers. Select your operating system as windows XP SP2. On the second option box select “Driver”. Note there are 2 pages of drivers. Most importantly get LAN, Display, Wi-Fi, and Sound. Also probably get chipset and Touchpad. There are multiple Wi-Fi drivers. Just download both. If the first one you try says you don’t have the supported hardware then just use the other one.
