If also rebooting the Wifi doesn't return, you can go to your manufacturer website and download the wifi driver, then reboot and see if the wifi comes back. If not, there is some problem hardware-related.

I just installed the latest Windows Update, but after installing it, my PC can no longer connect to wi-fi. The network troubleshooter only tells me to connect an ethernet cable and doesn't offer any solutions for how to fix the wireless connection at all. In fact, everything that had to do with wireless connections in Network and Internet Settings seems to be missing entirely. Connecting using an ethernet cable is now the only way to connect to the Internet on my PC. It's inexcusable for a Windows Update to do this to my PC.
