Surface 3 WiFi issues?

I experienced everything I read online regarding the Surface 3 and Surface Pro 3 wireless network issues.  My surface is running Windows 10 (4GB / 128GB model). After wakeup from sleep – network won’t connect, when it does – connection is so slow, and un-usable.  I opened a ticket with Microsoft and their steps to resolve are below.  The steps below resolved my issues.

I still do have 5GHz issues – in where speed of wireless connection is very slow.  I’m using Aerohive AP230 as my AP (  I have never had issues with these AP’s – they are rock solid.  I have Windows computers and Mac’s, iPhones etc. that connect just fine.


Here are the steps:

Run sfc/scannow from administrator command prompt (


  1. Go to “Device Manager”

  2. Tap on “Network Adapters”

  3. Tap and hold on Marvell AVASTAR Wireless-N Network Controller

  4. Click on Uninstall

  5. Click on OK ( Do not delete the driver )

  6. Close all of the windows

  7. Restart your Surface.

The Marvell WiFi driver will reinstall itself when the Surface is restarted.


  1. Shut down the device fully by holding down the power button for 15 seconds and then release it. Verify if the device is fully shut down by tapping on the Windows logo, if you won’t feel it vibrating, then that means that the device is fully shut down.

  2. Then press and hold the volume up rocker first and then follow the power button, holding both at the same time for 10 seconds and then release both buttons after 10 seconds.

  3. Tap on the power button to try and power on the device.
