Hello, I'm a newbie who doesn't quite understand how to use a Raspberry Pi fully,

I'm trying to get the latest PiPlay build to recognize/use a DLink WiFi adapter, but it currently won't work... I looked it up and found that you need to install a specific driver, but how do I do so? Keep in mind that I don't know how to access the command-line...

Is there a way to put the driver files into the SD-Card directly? How?
