A Fujitsu Stylistic 5031D
is not a network adapter, it's a TABLET PC
. It's simply amazing that you do not know how to create a proper request/thread for a driver or how to describe your hardware. This machine comes from the manufacturer with 2 different network devices, one LAN (Broadcom chip) and one WLAN (Atheros chip).
Try visiting the manufacturers website for drivers. You cannot use generic drivers on a tablet pc... you must use specific drivers from the laptop maker.
Fujitsu website design prevents direct links to their drivers. You have to click your way to the driver.
