Contents.Installationthe package, which includes the main program wpasupplicant, the passphrase tool wpapassphrase, and the text front-end wpacli.Optionally, also install the official AUR which provides wpagui, a graphical front-end for wpasupplicant, or AUR which is a fork from an earlier version of wpagui with a couple of fixes and improvements.OverviewThe first step to connect to an encrypted wireless network is having wpasupplicant obtain authentication from a WPA authenticator. In order to do this, wpasupplicant must be configured so that it will be able to submit the correct credentials to the authenticator.Once you are authenticated you need to assign an IP address, see.Connecting with wpacliThis connection method allows scanning for available networks, making use of wpacli, a command line tool which can be used to configure wpasupplicant. See for details.In order to use wpacli, a control interface must be specified for wpasupplicant, and it must be given the rights to update the configuration. Do this by creating a minimal configuration file:/etc/wpasupplicant/wpasupplicant.conf ctrlinterface=/run/wpasupplicantupdateconfig=1Now start wpasupplicant with:# wpasupplicant -B -i interface -c /etc/wpasupplicant/wpasupplicant.conf. Tip:. The default location of the control socket is /var/run/wpasupplicant/. Tip: To configure a network block to a hidden wireless SSID, which by definition will not turn up in a regular scan, the option scanssid=1 has to be defined in the network block.
Connection ManualFirst start wpasupplicant command, whose most commonly used arguments are:.B - Fork into background.c filename - Path to configuration file.i interface - Interface to listen on.D driver - Optionally specify the driver to be used. For a list of supported drivers see the output of wpasupplicant -h. nl80211 is the current standard, but not all wireless chip's modules support it.
wext is currently deprecated, but still widely supported.See for the full argument list. For example:# wpasupplicant -B -i interface -c /etc/wpasupplicant/example.conffollowed by a method to obtain an ip address manually as indicated in the, for example:# dhcpcd interface. Tip:. dhcpcd has a hook that can launch wpasupplicant implicitly, see. While testing arguments/configuration it may be helpful to launch wpasupplicant in the foreground (i.e. Without the -B option) for better debugging messages.At boot (systemd)The wpasupplicant package provides multiple service files:. wpasupplicant.service - uses, recommended for users.
wpasupplicant@ interface.service - accepts the interface name as an argument and starts the wpasupplicant daemon for this interface. It reads a /etc/wpasupplicant/wpasupplicant- interface.conf configuration file. wpasupplicant-nl80211@ interface.service - also interface specific, but explicitly forces the nl80211 driver (see below). The configuration file path is /etc/wpasupplicant/wpasupplicant-nl80211- interface.conf. wpasupplicant-wired@ interface.service - also interface specific, uses the wired driver.
The configuration file path is /etc/wpasupplicant/wpasupplicant-wired- interface.conf.To enable wireless at boot, enable an instance of one of the above services on a particular wireless interface. For example, the wpasupplicant@ interface systemd unit.Now choose and an instance of a service to obtain an ip address for the particular interface as indicated in the. For example, the dhcpcd@ interface systemd unit.
Tip: This setup can be used during system installation as well, though you may want to run using dhcpcd@ adapter.service to solicit an address. Wpacli action scriptwpacli can run in daemon mode and execute a specified script based on events from wpasupplicant. Two events are supported: CONNECTED and DISCONNECTED. Some are available to the script, see for details.The following example will use to notify the user about the events:#!/bin/bashcase '$2' inCONNECTED)notify-send 'WPA supplicant: connection established';;;DISCONNECTED)notify-send 'WPA supplicant: connection lost';;;esacRemember to make the script executable, then use the -a flag to pass the script path to wpacli:$ wpacli -a /path/to/script Troubleshooting. Note: Make sure that you do not have remnant configuration files based on the full documentation example /usr/share/doc/wpasupplicant/wpasupplicant.conf. It is filled with uncommented network examples that may lead random errors in practice.
Nl80211 driver not supported on some hardwareOn some (especially old) hardware, wpasupplicant may fail with the following error:Successfully initialized wpasupplicantnl80211: Driver does not support authentication/association or connect commandswlan0: Failed to initialize driver interfaceThis indicates that the standard nl80211 driver does not support the given hardware. The deprecated wext driver might still support the device:# wpasupplicant -B -i wlan0 -D wext -c /etc/wpasupplicant/example.confIf the command works to connect, and the user wishes to use to manage the wireless connection, it is necessary to the wpasupplicant@.service unit provided by the package and modify the ExecStart line accordingly:/etc/systemd/system/wpasupplicant@.service.d/wext.conf ServiceExecStart=ExecStart=/usr/bin/wpasupplicant -c/etc/wpasupplicant/wpasupplicant-%I.conf -i%I -Dnl80211,wext.

Note: Multiple comma separated driver wrappers in option -Dnl80211,wext makes wpasupplicant use the first driver wrapper that is able to initialize the interface (see ). This is useful when using mutiple or removable (e.g.
USB) wireless devices which use different drivers. Problem with mounted network shares (cifs) and shutdownWhen you use wireless to connect to network shares you might have the problem that the shutdown takes a very long time. That is because systemd runs against a 3 minute timeout. The reason is that WPA supplicant is shut down too early, i.e. Before systemd tries to unmount the share(s). A suggests a work-around by the wpasupplicant@.service as follows:/etc/systemd/system/wpasupplicant.service.d/override.conf UnitAfter=dbus.service Password-related problemsmay not work properly if directly passed via stdin particularly long or complex passphrases which include special characters.
This may lead to errors such as failed 4-way WPA handshake, PSK may be wrong when launching.In order to solve this try using here strings wpapassphrase ' or passing a file to the -c flag instead:# wpasupplicant -i -c /etc/wpasupplicant/example.confIn some instances it was found that storing the passphrase cleartext in the psk key of the wpasupplicant.conf network block gave positive results (see ). However, this approach is rather insecure. Using wpacli to create this file instead of manually writing it gives the best results most of the time and therefore is the recommended way to proceed.Problems with eduroam and other MSCHAPv2 connectionsEnsure that your config usesphase2='auth=MSCHAPV2'with a capital 'v' (see ). You could even omit this setting entirely, since MSCHAPV2 is the default.See also. contains full documentation of project, including wpacli commands not listed in manpage.
