I've been using this device without problem for almost a year. But just now, it suddenly turned off (the green light it has turned off) and it's no longer providing internet conection. I've tried unistalling and re-ibnstalling the drivers, and restarting the computer but it's still not working. The pc is detecting it as it shows the Wi-Fi 2 option when I connect it, but it says that the Wi-Fi 2 is disconected. Hope someone can help me fix it. thank you.
