How to connect to wifi from command line?
I'm assuming wpa_supplicant
and iw
is installed.
To connect to wifi through
wpa_supplicant
you need to create awpa_supplicant.conf
filenano /etc/wpa_supplicant.conf
with the following lines:
network={ ssid="wifi_name" psk="wifi_key" }
Or you can use wpa_passphrase
to create the configuration file (copy and past):
wpa_passphrase "Your_SSID" Your_passwd
Also you can write the wpa_supplicant.conf
directly through:
wpa_passphrase "Your_SSID" Your_passwd > /etc/wpa_supplicant.conf
to connect type the following command:
sudo ip link set wlan0 down
sudo ip link set wlan0 up
sudo wpa_supplicant -B -iwlan0 -c /etc/wpa_supplicant.conf -Dnl80211,wext
sudo dhclient wlan0
Note: Multiple comma separated driver wrappers in option
-Dnl80211,wext
makes wpa_supplicant use the first driver wrapper that is able to initialize the interface (see wpa_supplicant(8)). This is useful when using mutiple or removable (e.g. USB) wireless devices which use different drivers.
You can connect through wpa_supplicant
without wpa_supplicant.conf
file:
wpa_supplicant -B -i wlan0 -c <(wpa_passphrase "Your_SSID" Your_passphrase) && dhclient wlan0
You can visit the official documentation of Arch-linux to get more information about the configuration file and arguments.
you can connect through
nmcli
nmcli d wifi connect Your_SSID password Your_Psswd_here iface Your_interface
Example:
nmcli d wifi connect MYSSID password 12345678 iface wlan0
- Also you can connect through
wpa_cli
:
Open the terminal and type wpa_cli
To scan, type:
scan
scan_results
Create a network:
add_network
This will output a number, which is the network ID, for example 0
Next, we need to set the SSID and PSK for the network.
set_network 0 ssid "SSID_here"
set_network 0 psk "Passphrase_here"
Once the wireless has connected, it should automatically get an IP address.
if it doesn’t you can run the dhclient
to get an IP address via DHCP.
The dhclient
command ca be replaced with 2 ip
commands:
ip addr add IP-ADDRESSE/24 dev wlan0
ip route add default via ROUTE
iwctl
command line tools.
The iwd
package provide the iwctl
command line tools . The package isn't installed by default. To avoid any conflict the wpasupplicant.service
should be stopped/disabled.
for more details see this answer on U&L: Connect to wifi from command line on linux systems through the iwd (wireless daemon for linux)

To install wpa_supplicant on Debian, type
sudo apt install wpasupplicant
in the terminal. To create the wpa_supplicant.conf
file, type in
echo 'network={ssid="nameOfYourWiFiNetwork" psk="thePassword"}' >> /etc/wpa_supplicant.conf
