Feeling rather blonde here... i have lost my wireless connection on my acer notebook... where is the button/switch etc to give me the blue flashing light to demonstrate connection to my wireless internet?
Some machines have a physical toggle switch on the outside of the laptop case while others have a physical switch via function keys on your keyboard and i believe your acer will have the switch with the key commands as shown in this picture: http://cdn.slashgear.com/wp-content/uploads/2011/09/ACE...
This specific Acer laptop has the wireless toggle key attached to the "F3" key. So to use this toggle, you hold down your "Function" or "Fn" Key which is located on the lower left of your keyboard, next to the "Shift" and "Windows" keys. This Function Key is usually colored blue or gray, color coordinating with the various hot key s on the keyboard.
So anyway hold your blue Function key and tap the F3 key
