Hi all... I can't boot Apple's Hardware Test on this Mac Mini. Going over Wi-fi, i get an error with globe on screen... Over Eithernet, i just get the globe, with option to connect to wifi, via drop down.. Is this hardware related ? since the eithernet port and wifi work just fine within the OS. All other mac's connected to the same wi-fi router, using same password works just fine after powered on and pressing "D" at boot.
