It is possible to use wireless on a Debian “Lenny” Linux laptop?

I have a dual boot toshiba laptop on which I am running Windows 7 and the latest version of Debian “Lenny” Linux. I have tried all the built-in wi-fi utilities and can’t get any of them to work, I have also tried downloading driver from intel for linux but this also failed. Is it possible to use wi-fi on Lenny? I know Ubuntu and other breeds of Linux have better Wi-fi capabilities but I’m required to use Lenny as part of a university course I’m studying.
