Overview

Although it is possible to rely on CAT5 cable to establish your Raspberry Pi network connection, the extra tangle of wire will soon prove annoying. The instructions on this page will help you set up Raspberry Pi to have either wired or wireless network connection.

Bill of Materials

@Requires

Step 1. Configure network interfaces

  1. Save a backup copy of /etc/network/interfaces
  2. sudo vi /etc/network/interfaces set up Raspberry Pi for wireless and/or wired Ethernet connection 
# automatically install loopback network interface
auto lo
iface lo inet loopback
# use DHCP to determine Raspberry Pi IP address for first (eth0) network card
iface eth0 inet dhcp
# automatically install wireless network interface
auto wlan0
allow-hotplug wlan0
iface wlan0 inet dhcp
 wpa-scan-ssid 1
 wpa-ap-scan 1
 wpa-key-mgmt WPA-PSK
 wpa-proto RSN WPA
 wpa-pairwise CCMP TKIP
 wpa-group CCMP TKIP
 wpa-ssid "ENTER-YOUR-WIRELESS-ROUTER-SSID"
 wpa-psk "ENTER-YOUR-WIFI-PASSWORD"
iface default inet dhcp

Step 2. Verify network connections

  1. sudo reboot reboot to apply your interface changes
  2. ifconfig list network interfaces to see your wired (eth0) as well as your wireless (wlan0) internet addresses:
