Hi, I currently have a Microsoft Surface Pro 1st Version that originally shipped with Windows 8 Professional. I had installed Windows 7 Ultimate SP1 x64, got 99% of the drivers working, except for the Wi-fi driver. It has a Marvell Avastar 350n Wireless Card with 802.11n capabilities. The Windows 8, 8.1 and 10 drivers don't work. Is there a way to modify the driver, or is there a hidden Windows 7 driver?
