Connecting to Your Router
The Raspberry Pi Model A has no network connection on the board. The Model B Raspberry Pi has an Ethernet socket on the right edge of the board, indicated in Figure 3-1. Use this socket to connect your Raspberry Pi to your Internet router with a standard Ethernet cable.
The Raspberry Pi automatically connects to the Internet when used with a router that supports the Dynamic Host Configuration Protocol (DHCP), which means it works with most domestic routers. For advice on troubleshooting your Internet connection, see Appendix A.
