My laptop (Dell D630) has Intel Pro/Wireless 3945ABG interface. Recently I upgraded the driver to the latest version (12.4.4.5) and had the issue of the frequent connection drop. Then I downgraded the driver to the previous version (12.4.3.9) and everything is back to normal.
See the error message when the connection was dropped.
