Why can I not share my internet via Wifi?

[Windows Central Question]

I was trying to connect my chromecast in a hotel via a mobile hotspot on my laptop. I had the wifi hotspot setup on my computer and the chromecast connected, but it kept sporadically disconnecting. I tried messing around with some of the adapter settings to get it working, but now I only have the option to share my internet via ethernet. The option for Wifi doesn't appear anymore. Can someone assist me in re-enabling the wifi option?

Thanks

1) Press ctrl+x
2) Open device manager
3) Under network adapters if you see your WiFi card with yellow question mark, you need to reinstall drivers

Or you may need to simply turn it on again using the FN+F(x which corresponds to the Wifi on/off shortcut key) on your laptop.
