Windows 10: Marvell AVASTAR network controller or Qualcomm Atheros QCA61x4A Wireless Network Adapter is...

I have XPS13 and it had been working fine. However sice yesterday the wifi tab went missing. It does not show up in network setting. I searched on Microsoft website and it said to go to device manager - network adapter. It said if "Marvell AVASTAR network controller or Qualcomm Atheros QCA61x4A Wireless Network Adapter is missing" contact them. These are indeed missing And Im wondering what the solution is. Also, why did this suddenly happen?
