adventures with microcomputers prototyping with raspberry pi

6. Connectivity WiFi

WiFi

There is one file that needs to be configured to setup WiFI on the Raspberry Pi: /etc/wpa_supplicant/wpa_supplicant.conf.

  1. Connect to the Raspberry Pi via FTDI
  2. Navigate to /etc/wpa_supplicant/wpa_supplicant.conf: cd /etc/wpa_supplicant/
  3. Open wpa_supplicant.conf with nano: sudo nano wpa_supplicant.conf and move on to the next sequence (Configuring wpa_supplicant)

Configuring wpa_supplicant

Here is what wpa_supplicant would look like with only one network (with nonsense credentials):

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

network={
   ssid="WIFINETWORKNAME"
   psk="WIFINETWORKPASSWORD"
}

To configure it for a your network simply insert the WiFi network name in ssid and the password in psk. Note that you have to use quotes for both of these fields. Save changes, exit, and reboot to confirm that you can connect to the network after logging back in.
