Here’s a quick rundown on how o connect your Raspberry Pi to the internet using a wired network connection, from sarful via hackster.io:
You want to connect your Raspberry Pi to the Internet using a wired network connection. Solution: First, if you have a Raspberry Pi model A, A+, or Zero, there is no RJ45 connector for Ethernet. In this case, your best option for Internet access is to use a wireless USB adaptor. If you have a Raspberry Pi model B, plug an Ethernet patch cable into its RJ45 socket and then connect the other end to a spare socket on the back of your home router. The figure shows an original Raspberry Pi 1 where the Network LEDs are next to the audio socket. On a Raspberry Pi 2, the LEDs are built into the Ethernet socket itself.
