Networking and connecting your Raspberry Pi to the Internet via a USB Wi-Fi dongle
By adding a USB Wi-Fi dongle to the Raspberry Pi's USB port, even models without built-in Wi-Fi can connect to and use the Wi-Fi network.
Getting ready
You will need to obtain a suitable USB Wi-Fi dongle; and in some cases, you may require a powered USB hub (this will depend on the hardware version of the Raspberry Pi you have and the quality of your power supply). General suitability of USB Wi-Fi dongles will vary depending on the chipset that is used inside and the level of Linux support available. You may find that some USB Wi-Fi dongles will work without installing additional drivers (in which case you can jump to configuring it for the wireless network).
