Raspberry Pi networking
You'll probably want to connect your Raspberry Pi to your local network or the internet. You can use any of the following options to do this:
Connecting via Ethernet
The Raspberry Pi has an Ethernet port, alongside the USB ports. If your Raspberry Pi is situated close to a router, access point, or switch, you can connect to a network using an Ethernet cable.
Once you've plugged the Ethernet cable into the Raspberry Pi and the other end into an access point, your Raspberry Pi will automatically connect to the network.
Connecting via WiFi
If you have a Raspberry Pi 3, then there is built-in WiFi. If you're using an earlier version of the Raspberry Pi, then you'll need a USB WiFi dongle.
Some WiFi dongles, when used with the Raspberry Pi, are simple plug and play devices. Others require specific drivers, and may not be compatible with the Raspberry Pi. Make sure you read the device manufacturer's documentation before making a purchase.
