i have recently bought a raspberry pi 3. i have done some projects with it... and for the period of 3 weeks i've left it idle.
later when i turned it on, the WiFi ,Bluetooth doesn't work now, it says no wireless interfaces found.
when ive searched the other forums it is said , if it is under warranty , element`14 will test the board and replace/repair it if any case found?
how can i proceed further, whome to contact, where to contact?
