You probably won’t need to install driver software or even touch a command line. However, this isn’t always the case, especially as new cards come on the market, so you should still have a good understanding of how Wi-Fi works under Linux. This chapter starts out with an explanation of what you need to do with some common distributions and a common radio card, and then gets into the details you need to know to take things a little further, including radio chipsets, drivers, kernel compilation, the PCMCIA subsystem, and the Linux wireless tools.
