How to Fix Surface Pro 3 Wireless Adapter in Windows 8.1

I know that software updates are important to improve your computer experience and fix security holes, but in the latest Patch Tuesday, which Microsoft released on August 12, which also included the August Update (Update 2), It hurts the Surface Pro 3 more than it helps. Since updating the Surface Pro 3 to the latest firmware update in August, I’ve had several Wi-Fi issues.

For example, almost every time I wake up the tablet, I see that it is not connected to my wireless network; when I log in, sometimes I’m lucky enough to see it automatically reconnect. Other times, I need to restart Windows to get back online.

But today I see something totally new, after waking up my Surface, I realize that the wireless adapter was disabled by itself. Walking to Control Panel and navigating to Network Connections, I tried to reactivate the adapter but it didn’t work.

So, if you are experiencing the same issue, there is an easy solution, just follow the steps below:

Surface Pro 3 Wireless Network Adapter Repair

  1. Tap and hold the Home button and select Device manager

  2. Meet up Network adaptersexpand and hold “Marvell AVASTAR Wireless-AC Network Controller”

  3. Choose Uninstall and select “Remove the driver software for this device.” and press Alright.

  4. You have just removed the Surface Pro 3 Wireless Adapter driver. Now you just need to reinstall the driver; To do this, follow these steps:

    In Device Manager, tap the Scan toolbar icon (the little PC with a magnifying glass on top). This action will scan your Surface Pro 3 for changes, at which point Windows 8.1 should automatically detect and reinstall the appropriate driver.

Now go back to Network Connections and hopefully you will see that the wireless adapter is enabled again. Go ahead and connect to your local network as it should work normally. However, you may need to re-enter the wireless password.

I still don’t know the reason why the Surface Pro 3 Marvell AVASTAR adapter disabled on its own, but I will continue to investigate and update this article accordingly.
