Hardware and software networking configuration
Since we will need Internet connectivity to install tools and utilities, let's now look at the Pi hardware and software networking configuration in more detail; the wireless configuration is first since many project designers may prefer a wireless connection.
There are many Pi-compatible wireless adapters and you may even have bought one as part of your initial kit. The most common recommendation is that you use a Wi-Fi adapter that uses the
Realtek RTL8188CUS chipset. The driver for this chipset (rtl8192cu) is included in the Raspbian distribution, so enabling this particular type of Wi-Fi adapter is easy.
