[https://w1.fi/wpa_supplicant/ wpa_supplicant] is a WPA Supplicant for Linux, BSD, Mac OS X, and Windows with support for WPA, WPA2 (IEEE 802.11i / RSN), and WPA3. It sets up connections to wireless networks.

To avoid having your network password in accessible plaintext on your system or in your version control consider using [https://search.nixos.org/options?show=networking.wireless.~~environmentFile~~&from=0&size=50&sort=relevance&type=packages&query=networking.wireless networking.wireless.~~environmentFile~~].

To avoid having your network password in accessible plaintext on your system or in your version control consider using [https://search.nixos.org/options?channel=25.05&show=networking.wireless.secretsFile&from=0&size=50&sort=relevance&type=packages&query=networking.wireless networking.wireless.secretsFile].

Another example of simple wpa2 auth:

networking.networkmanager.enable = false;

networking.wireless = {

enable = true; # Enables wireless support via wpa_supplicant.

networks."MYSSID".psk = "myPresharedKey";

extraConfig = "ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=wheel";

# output ends up in /run/wpa_supplicant/wpa_supplicant.conf

};

== WEP support ==

You may encounter a situation where you are in a hotel, for example, and the WiFi uses WEP encryption. As of version 2.10 of <code>wpa_supplicant</code>, WEP support is not enabled by default. To enable it, add the following to your <code>configuration.nix</code>:

nixpkgs.overlays = [

(self: super: {

wpa_supplicant = super.wpa_supplicant.overrideAttrs (oldAttrs: rec {

extraConfig = oldAttrs.extraConfig + ''

CONFIG_WEP=y

'';

});

})

];

</syntaxHighlight>

This builds <code>wpa_supplicant</code> with WEP support.
