Atheros Communications develops products related to network and wireless communications, including the network adapters found in many laptop computers. If your Atheros adapter does not work, you have systems within your Windows-based computer that will help you fix the adapter so your communications will run smoothly again. Your computer will search for updated drivers and help you download and install a working driver. If you are unable to download a new driver through the Windows device manager as instructed, the best way is to visit your computer manufacturer's website and use their support pages to locate the appropriate driver.
