Wicd is a network connection manager that can manage wireless and wired interfaces, similar and an alternative to NetworkManager. Wicd is written in Python and GTK+, requiring fewer dependencies than other network managers. Alternatively, a version of Wicd for KDE, written in Qt, is available from the Arch User Repository. Wicd can also run from the terminal in a curses interface, requiring no X server session or task panel (see #Running Wicd).


Base package

Install wicd, available in the official repositories. It includes everything needed to run the wicd daemon and the wicd-cli and wicd-curses interfaces.

GTK+ client

For a GTK+ front-end, install wicd-gtk, available in the official repositories. It includes everything needed to run the GTK interface of wicd and the autostart file for the client to appear in the system tray.

KDE client

For a KDE front-end, install wicd-kdeAUR, available in the AUR.


To enable visual notifications about network status, you need to install the notification-daemon.

If you are not using GNOME, you will want to install xfce4-notifyd instead of the notification-daemon, because it pulls a lot of unnecessary GNOME packages.


The wicd-bzrAUR buildscript is available in the AUR, which should build the latest development branch. If you need an alternative version or you just want to roll your own package, you can easily build it using ABS.

Getting started

Initial setup

Wicd provides a daemon that must be started.

Warning: Running multiple network managers will cause problems, so it is important to disable all other network management daemons.

First, stop all previously running network daemons (like netctl, netcfg, dhcpcd, NetworkManager).

Disable any existing network management services, including netctl, netcfg, dhcpcd, and networkmanager. Refer to Systemd#Using_units.

Note: You might need to stop and disable the network daemon instead of netctl, which is a current replacement for network service. If unsure, try disabling both.

Start the wicd systemd daemon and enable it at system start up.

Add your account to users group:

# gpasswd -a USERNAME users
Note: The Unix group that dbus allows to access wicd is subject to change, and may be different than users. Check which policy group is specified in /etc/dbus-1/system.d/wicd.conf, and add your user to that group.

If you added your user to a new group, log out and then log in.

Running Wicd in Desktop Environment

If you have installed the wicd-gtk and entered the desktop environment. Open a virtual terminal to run one of the following commands.

  • To start Wicd as system service, run:
$ systemctl start wicd.service
  • To load Wicd, run:
$ wicd-client
  • To force it to start minimized in the notification area, run:
$ wicd-client --tray
  • If your desktop environment does not have a notification area, or if you don't want wicd to show tray icon, run:
$ wicd-client -n

Running Wicd in Text Mode

If you did not install wicd-gtk then use wicd-cli or wicd-curses:

$ wicd-curses
Note: Wicd does not prompt you for a passkey. To use encrypted connections (WPA/WEP), expand the network you want to connect to, click Advanced and enter the needed info.


The wicd-gtk package puts a file in /etc/xdg/autostart/wicd-tray.desktop, which will autostart wicd-client upon login to your DE/WM. If so, enabling the wicd system service is enough:

$ systemctl enable wicd.service

If /etc/xdg/autostart/wicd-tray.desktop does not exist, you can add wicd-client to your DE/WM startup to have the application start when you log in.

Note: If wicd-client is added to DE/WM startup when /etc/xdg/autostart/wicd-tray.desktop exists, you will have an issue of two wicd-client instances running.


Wicd has the ability to run scripts during all stages of the connection process (post/pre connect/disconnect). Simply place a script inside the relevant stage folder within /etc/wicd/scripts/ and make it executable.

The scripts are able to receive three parameters, these being:

$1 - the connection type (wireless/wired).
$2 - the ESSID (network name).
$3 - the BSSID (gateway MAC).

Stop ARP spoofing attacks

The script below can be used to set a static ARP, to stop ARP spoofing attacks. Simply change the values within the case statement to match those of the networks you want to set static ARP entries for. Launch it as root:

#Set the parameters passed to this script to meaningful variable names.

if [ "${connection_type}" == "wireless" ]; then

        #Change below to match your networks.
        case "$essid" in
                arp -s 00:11:22:33:44:55
                arp -s 10:11:20:33:40:50
                arp -s 11:33:55:77:99:00
                echo "Static ARP not set. No network defined."

Change MAC using macchanger

See the relative article.

The script below can be used to change the MAC address of your network interfaces.

To change the MAC whenever you connect to a network, place this script under /etc/wicd/scripts/preconnect/.

Take a look at macchanger --help to adjust the macchanger command to your liking.

#!/usr/bin/env bash


if [[ "${connection_type}" == "wireless" ]]; then
        ip link set wlp2s0 down
        macchanger -A wlp2s0
        ip link set wlp2s0 up
elif [[ "${connection_type}" == "wired" ]]; then
        ip link set enp1s0 down
        macchanger -A enp1s0
        ip link set enp1s0 up


See Network configuration#Troubleshooting for troubleshooting wired connections and Wireless Setup#Troubleshooting for troubleshooting wireless connections. This section covers only problems specific to wicd.

Autoconnect on resume from hibernation/suspension

If for some reasons autoconnect on resume from hibernation or suspension does not work automatically, you can manually restart Wicd by enabling the following service file for your user.

Description=Restart Wicd autoconnect service on resume



Importing pynotify failed, notifications disabled

In case the python2-notify package did not get installed automatically. You can install it from Official Repositories.

Dbus connection error message

If wicd suddenly stopped working and it complains about dbus, it is quite likely that you just need to remove wicd fully, including and all its configuration files, and re-install it from scratch:

# pacman -R wicd
# rm -rf /etc/wicd /var/log/wicd /etc/dbus-1/system.d/wicd*
# pacman -S wicd

Check this link for more details: https://bbs.archlinux.org/viewtopic.php?pid=577141#p577141

Wicd-client also throws a dbus connection error message ("Could not connect to wicd's D-Bus interface.") when wicd is not running due to a problem with a config file. It seems that sometimes an empty account gets added to /etc/wicd/wired-settings.conf in which case you simply have to remove the


and restart wicd.

If the above doesn't work you could try https://bbs.archlinux.org/viewtopic.php?pid=1268721

Problems after package update

Sometimes the wicd client fails to load after a package update due to D-Bus errors.

A solution is to remove the config files in the /etc/wicd/ directory.

# systemctl stop wicd
# rm /etc/wicd/*.conf
# systemctl start wicd

Note about graphical sudo programs

If you are receiving an error about wicd failing to find a graphical sudo program, install one of gksu, ktsussAUR, or kdebase-runtime, then use the relative command:

$ ktsuss wicd-client -n
$ gksudo wicd-client -n
$ kdesu wicd-client -n

Making eduroam work with wicd

Note: You may try the AUR package wicd-eduroamAUR first. It will appear in wicd as "eduroam". If it does not work for you, try the following.

This profile will only work for eduroam institutions which use TTLS and will not work for PEAP (you can find a PEAP profile here: Eduroam wicd).

Save the following as /etc/wicd/encryption/templates/ttls-80211

name = TTLS for Wireless
author = Alexander Clouter
version = 1
require anon_identity *Anonymous_Username identity *Identity password *Password 
protected password *Password
optional ca_cert *Path_to_CA_Cert cert_subject *Certificate_Subject


       phase2="auth=MSCHAPv2 auth=PAP"


Open a terminal

# echo ttls-80211 >> /etc/wicd/encryption/templates/active

Open wicd, choose TTLS for Wireless in the properties of eduroam, and enter the appropriate settings for your institution. The format of the subject match should be something like "/CN=server.example.com".

NB. This only works in my institution by commenting subject_match, which is not secure, but at least it connects.

Two instances of wicd-client (and possibly two icons in tray)

See the note in Wicd#Running_Wicd about the autostart file in /etc/xdg/autostart and the forum post and bug report provided in Wicd#External_Links. Essentially, if /etc/xdg/autostart/wicd-tray.desktop exists, remove it. You only need the wicd service enabled in systemd.

Bad password using PEAP with TKIP/MSCHAPV2

The connection template PEAP with TKIP/MSCHAPV2 requires the user to enter the path to a CA certificate besides entering username and password. However this can cause troubles resulting in a error message of a bad password *. A possible solution is the usage of PEAP with GTC instead of TKIP/MSCHAPV2 which does not require to enter the path of the CA cert.

Wicd skips obtaining IP address on wlp

This can be caused by dhcpcd running alongside wicd as systemd service. A solution would be to stop/disable dhcpcd.

dhcpcd not running

Normally it should not be required, nor recommended to run the dhcpcd service next to wicd. However, if you encounter the error message that dhcpcd is not running, then you can try running dhcpcd and see if you encounter any incompatibilities when using both services at the same time.

# systemctl start dhcpcd

Alternatively, as a workaround you might consider switching to dhclient in the Wicd settings.

Note: If you get send_packet: Network is unreachable errors, then try increasing the timeout in /usr/share/dhclient/dhclient.conf.
