I installed the Windows 10 April 2018 Update. After installing I got a warning that Check Point client was not compatible. At this time I had a network connection. I then uninstalled Check Point client.
After this my WiFi connection showed "No Internet, Secured" and troubleshooter shows "Windows couldn't automatically bind the IP protocol stack to the network adapter".
I think "Issues with network adapters on Windows 10 caused by Check Point Endpoint Security Client self-protection" might be what happened: https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doGoviewsolutiondetails=&solutionid=sk116313
I've since then tried a lot of things.

- Resetting things using netsh
- Network reset in Windows
- Going back to the previous Windows version
- Installing newer Check Point client
- Uninstalling newer Check Point client
- Uninstalling Hyper-V Windows feature
- Updating network adapter drivers
Things that might matter.
- Computer is running BitLocker encrypted drives.
- It's an MSI GT62VR 6RE notebook
Can I get back to a working network connection without reinstalling Windows?
