Description: Instructions for setting up a wifi link to aid in development.Tutorial Level: INTERMEDIATE
Next Tutorial: Tether Network Setup
If you are going to use the Pi's Ethernet port for the tether connection to the surface, we recommend adding a miniature wifi dongle and setting up wifi. This will enable easy development and will leave your Ethernet port free for a direct connection to a surface computer (see below.) First, install the wpasupplicant package if you haven't already:
sudo apt-get update sudo apt-get install wpasupplicant
Then write your network connection details to /etc/wpa_supplicant/wpa_supplicant.conf. It should look something like this:
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
network={
ssid="YourWifiNetworkName"
proto=RSN
key_mgmt=WPA-PSK
pairwise=CCMP TKIP
group=CCMP TKIP
psk="YourWifiNetworkPassword"
}Next, configure your wireless adapter by adding or modifying the settings in /etc/network/interfaces:
allow-hotplug wlan0 iface wlan0 inet manual wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf iface wlan0 inet dhcp auto wlan0
Finally, restart your network interface by restarting the computer or the networking daemon and test out your new connection!
sudo /etc/init.d/networking restart sudo ifup wlan0 ping -I wlan0 google.com
