GNU+Linux Mint 15 now on my Laptop

Olivia just arrived at my Laptop.
GNU+Linux Mint 15 after I needed to reinstall the system because I switched accidentally WIFI to OFF, which causes my Ubuntu (and Mint) to disable it permanently with no way to enable it again.
So I thought, I give Mint a run. Works fine on my Laptop. At least until I hit this damn Wifi-disable button in the tray pull-down menu again.
