Tech Tips -- Restoring Wireless Ability on Laptop

Yesterday I was experimenting with Becca's projector with the new laptop in the dining room. I was pushing "fn" and various "f" keys on the top. I somehow disabled the laptop's (in dining room) ability to do wireless.

After a lot of experimenting, I discovered that if you push fn with f2 it restores wireless ability. The F2 key has a small blue "" on it which was the key.
