wifi icon is no longer on my taskbar. I went to properties-customize- select icon in notification area. wifi is not an option. I have my wired hook up listed but nothing for wifi. I had wifi prior to turning wifi sense off. Now when I go to network settings wifi is not even listed. Any recommendations??

Uninstalling and reinstalling the Wireless Drivers worked for me.

1. From the Desktop, right click This PC, and click Manage.
2. In the left pane, under System Tools, click Device Manager. 
3. Scroll down and go to the Network Adapters list.
4. Right click your wireless adapter (in my case it is (Intel(R) Dual Band Wireless-AC3160) and click Uninstall.
5. I restarted my PC after this and then went back to Device Manager, right clicked on Network Adapters, and clicked Scan for hardware changes.
6. Ideally it should have detected and installed the Wireless drivers by itself, but the WiFi wasn’t working still, so I had to perform one more step.
7. I right clicked on the wireless adapter and clicked Update Driver Software, then clicked Browse my computer for driver software, selected the latest drivers from the list, and my WiFi was up and running again and even the WiFi icon was being displayed on the taskbar.

Note: Simply doing Update Driver Software in the first place did not work for me, hence I had to uninstall and reinstall the drivers. You can try that first however, and see if it works for you.
