I ran into an issue with a Windows laptop I was using for work. The internet connection dropped. I tried restarting my laptop but that didn't work.
I then tried using the troubleshooter under Settings to see if that would improve matters. Once the troubleshooter was finished then only option I could see in the Network options was Airplane Mode. Uh oh.
I tried an number of approaches with no joy but I came across this article that provided a good step by step approach to fix the issue. If you have a Windows machine and all the Wi-Fi options disappear then this is a good starting point if you're trying to fix the problem yourself.
