Laptop internet not working?

At first, it said my network adapter wasn't working, then the next day, it was fine. But now my wireless capability is turned off and no function key can turn it back on. I've pressed the Fn function button with the one that has the Wi-Fi symbol, i've restarted and scoured that device manager page in the control panel, but nothing is working. What do i do?

My laptop is a lenovo thinkpad edge

You take it to a technician and pray
