How do I turn on my built-in wi-fi antenna? It has to be controlled internally, no external key/button... I don't know what the problem is. One day I can print from the my Inspirion 15 7000 series laptop and the next day, the wi-fi won't work. Have to connect to printer by usb cord! Have been checking my cable company's solutions. Have tried using the Fn key with F2 key. I can't find the exact combo in manuals!! Help! I need to print from other places in my house!
THANKS!
