It tested the OS and it installed the WIFI adapter. Yé!! I installed the OS (it prompt mw if I want the WIFI adapter driver install clic yes) and ... I have to be connect on the internet to install the WIFI adapter driver!!! Serious!!?? lol
That's why I always state that one should "Try Zorin", get the drivers installed, then after everything works, "Install Zorin"... the drivers pulled in under "Try Zorin" should already be present and thus be installed when you subsequently run "Install Zorin".
You'll note that if you connect to the internet under "Try Zorin", your WiFi connection will be automatically set up to connect after you're done with installation.
