Pre-setup
- Power off Raspberry Pi
- Insert the wifi adapter purchased from http://www.diygadget.com into one of the usb port on Raspberry Pi.
- Connect your USB keyboard.
- Connect your monitor with the HDMI cable.
- Power on Raspberry Pi
USB wifi adapter need additional power to work, if your power supply cannot provide enough power to your Pi, you can either switch to a better power supply or use a powered usb hub.
Config interfaces file
In console, run the following command:
sudo nano /etc/network/interfaces
This is the original content of the interfaces file:
auto lo iface lo inet loopback iface eth0 inet dhcp allow-hotplug wlan0 iface wlan0 inet manual wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf iface default inet dhcp
If you want your router to assign an IP address automatically to your Pi, modify interfaces file to:
auto lo iface lo inet loopback iface eth0 inet dhcp allow-hotplug wlan0 auto wlan0 iface wlan0 inet dhcp wpa-ssid <your wireless access point ssid name> wpa-psk <your wireless access point password> # wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf # iface default inet dhcp
If you want to have a static IP address of your Pi, modify interfaces file to:
auto lo iface lo inet loopback iface eth0 inet dhcp allow-hotplug wlan0 iface wlan0 inet static address 192.168.1.100 netmask 255.255.255.0 gateway 192.168.0.1 wpa-ssid <your wireless access point ssid name> wpa-psk <your wireless access point password> # wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf # iface default inet dhcp
(Change 192.168.1.100 to the IP you want to use).
