Piece of cake to use oracle very easy to set up I put win10 on machine first tweaked it then virtual win7
But you need at least 8gig ram for it all to operate smoothly and a win7 iso file or full install disk
and its free software
check in device manager for the wireless controller settings if not there reinstall the wi fi settings
check in services.msc that the wireless wlan auto config setting is started.
if all is lost a usb wi-fi dongle will get you connected

also check in task manager "performance" tab available memory for programs to run.On 2gig you would not have much memory available to use...
