If the burned in MAC isn't working the MAC is likely filtered or blocked somewhere along the line, keep digging. Perhaps its being contained by WIDS/WIPS or an explicit blocks via group policy.... just as a matter of principle since its a WPA2-PSK and Windows: Update the windows drivers. Open Power Shell or Command prompt and Type the following command to view wireless settings and press Enter: netsh wlan show interfaces Does this show your actual PHYSICAL MAC? If so, proceed. If not make sure random mac is deleted by flipping the switch in wireless connection's. Rinse and repeat Open Power Shell or Command prompt and type the following command to view the wireless network profiles saved on your computer and press Enter: netsh wlan show profiles How many saved profiles are here? If the user is like most typical user there will be a whole heck of a lot. Many of which are invalid, stale, old ,corrupt. In Power Shell or Command prompt Enter: netsh wlan delete profile name=* This will flush the profiles but you may want to also eradicate them from the registry: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkList\Profiles Reboot and try to connect using the actual MAC, you will have to enter the PSK for your network again, so have it handy. Also, to rule out the actual NIC you could try replacing it..... I still suspect its blocked or contained somewhere.
