Take a look at the bottom right-hand side of your screen. Just to the left of the clock, is your signal-strength indicator. If you see an "X" through it- This usually indicates that your Wi-Fi device has no power or that it has been disabled. If you have a laptop computer, try to find a button or switch on the laptop casing for the Wi-Fi (It usually has a small antenna icon on it). If your laptop doesn't have a button or slide on the casing, try enabling Wi-Fi by using the keyboard. Look for the antenna icon on one of the upper rows of keys. Press and hold "fn" (located on the bottom left of the keyboard), and press the key with the antenna icon on it. Release the keys. If you have a desktop computer with a USB wireless adapter, unplug it, and plug it back in. Wait a few seconds, and keep an eye on the signal-strength indicator on the bottom right by the clock- if the "X" changes back to normal bars, that was the problem.
