If you're an idiot and you're using a computer, this is what you do.
1. Get on your hands and knees and go under your desk
2. Find the thing that your screen plugs into, this is called a "COMPUTER", can you say "COMPUTER"?
3. Find the power button, this button when pressed will turn the computer "ON". If it is already on, most of the time it will shut it off.
4. Shut off the computer (See step #3 if you don't know how)
5. Now, go to the back of the computer. This is the part of the computer where everything plugs into (For example your screen)
6. Look for a wire that looks like a phone cable, but a little bit bigger. This is called your "ETHERNET" cable. It is what connects you to the internet.
7. Unplug "ETHERNET" cable.
8. Problem Solved.
