wpa_supplicant.conf

Reference info for wpa_supplicant.conf:

I got tired of looking through pages of documents to find the information I mostly use for setting up wpa_supplicant.conf on my Raspberry Pi devices. So, I'm putting it here.

If you are looking for a way to setup DHCP or Static settings for your networks follow the example under ### Other Options ###.

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

#
# home network; allow all valid ciphers
network={
    ssid="home"
    scan_ssid=1
    key_mgmt=WPA-PSK
    psk="very secret passphrase"
    priority=5
}

# This will connect to any open wifi connection
# if no other connection is available.
network={
    key_mgmt=NONE
    priority=-1
}

### Other Options ###
network={
    ssid="SCHOOLS NETWORK NAME"
    psk="SCHOOLS PASSWORD"
    id_str="school"
}

network={
    ssid="HOME NETWORK NAME"
    psk="HOME PASSWORD"
    id_str="home"
}

The following is part of the ### Other Options ### setup. Edit /etc/network/interfaces with iface school inet static and iface home inet dhcp in it so it looks something like this:

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 school inet static
address 192.0.2.7
gateway 192.0.2.254
netmask 255.255.255.0

iface home inet dhcp
