My Mediatek MT7630E 802.11bgn Wi-Fi Adapter is also malfunctioning, It says it's functioning properly but the F12 function light is amber and I can't change it. When I trouble shoot, it tells me to 'use the wi-fi button on the front or side of your computer to turn on your Mediatek MT7630E 802.11bgn Wi-Fi Adapter' I can't find such a button, and the PDF manual does not show one.
