Set up wifi #

If you're setting up your wifi from an SD card you can add the following in /wpa_supplicant.conf (along with a blank ssh file to enable ssh). Otherwise add it to /etc/wpa_supplicant/wpa_supplicant.conf:

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

network={
  ssid="ATT69696969"
  psk="password"
  key_mgmt=WPA-PSK
}

You can add multiple network blocks for multiple networks. You can encrypt your psk with wpa_passphrase [ssid-name] [password-name].
