    Sooyeon, 

    I apologize that you are having a problem with your gateway. You need to do a hard reset on the gateway. I have included instructions below.

    1. Unplug the AC adapter from the gateway.
    2. With a safety pin or paper clip, press and hold the reset button on the side of the gateway.
    3. Plug the AC adapter back in while continuing to hold down the reset button until the yellow LED light blinks.
