Edit: getting several comments that this didn’t work. Unfortunately I don’t own this laptop so I can test to see if this solution is still valid. It has worked for me twice. (April 2018 ish)

If you upgrade Windows 10 (presumably by using the media creation tool) you may find the WiFi no longer works. (14 inch laptop.)

I had this problem and called Unisurf for a solution. Here is their solution, which worked:

      I have spent 2 days trying to get this to work and have had no luck
      I have called unisurf support, they are not helpful. they can not even tell me what version 32 or 64 Bit. I would never buy another unisurf product.

    I have to keep uninstalling Bluetooth and restarting my unisurf laptop. Even without WiFi enabled the Bluetooth spazzes out and sound ceases at least once every Netflix stream or video download. This is unnaceptable and they need to do something about trashtops being allowed to be sold. The Bluetooth is cheap and faulty in unisurf.

    If you are thinking of buying a Unisurf. DONT. Pay a little more for a brand name. You will thank me.
