Wireless Networks
For a desktop installation using NetworkManager (e.g., GNOME), you just
have to make sure the user is in the networkmanager
group and you can
skip the rest of this section on wireless networks.
NixOS will start wpa_supplicant for you if you enable this setting:
{
networking.wireless.enable = true;
}
NixOS lets you specify networks for wpa_supplicant declaratively:
{
networking.wireless.networks = {
echelon = { # SSID with no spaces or special characters
psk = "abcdefgh";
};
"echelon's AP" = { # SSID with spaces and/or special characters
psk = "ijklmnop";
};
echelon = { # Hidden SSID
hidden = true;
psk = "qrstuvwx";
};
free.wifi = {}; # Public wireless network
};
}
Be aware that keys will be written to the nix store in plaintext! When
no networks are set, it will default to using a configuration file at
/etc/wpa_supplicant.conf
. You should edit this file yourself to define
wireless networks, WPA keys and so on (see wpa_supplicant.conf(5)).
If you are using WPA2 you can generate pskRaw key using
wpa_passphrase
:
$ wpa_passphrase ESSID PSK
network={
ssid="echelon"
#psk="abcdefgh"
psk=dca6d6ed41f4ab5a984c9f55f6f66d4efdc720ebf66959810f4329bb391c5435
}
{
networking.wireless.networks = {
echelon = {
pskRaw = "dca6d6ed41f4ab5a984c9f55f6f66d4efdc720ebf66959810f4329bb391c5435";
};
};
}
or you can use it to directly generate the wpa_supplicant.conf
:
# wpa_passphrase ESSID PSK > /etc/wpa_supplicant.conf
After you have edited the wpa_supplicant.conf
, you need to restart the
wpa_supplicant service.
# systemctl restart wpa_supplicant.service
