Toshiba Tecra A3 Notebook Wireless LAN Driver 220.127.116.11 for Windows XP/2000.
For the Tecra A4, with Windows 2000, the Intel ProSet software should only be installed immediately after installation of the Intel Wireless LAN driver.
There may be problems starting Windows 2000 if any other software is installed between the installations of the Intel Wireless LAN driver and Intel ProSet.
Follow this installation sequence:
1. Install the Intel Wireless LAN driver (It's not necessary to restart Windows).
2. Install Intel ProSet, immediately afterward -- before installing any other software.
If you wish to install the Intel ProSet software, some time after the installation of the Intel Wireless LAN driver, then un-install the Intel Wireless LAN driver, and follow the steps above.
