There are several command-line tools for managing a wireless network interface in Linux systems. A number of these can be used to simply view the wireless network interface status (whether it is\u00a0up<\/strong>\u00a0or\u00a0down<\/strong>, or if it is connected to any network), such as\u00a0iw<\/strong>,\u00a0iwlist<\/strong>,\u00a0ip<\/a>,\u00a0ifconfig<\/a>\u00a0and others.<\/p>\n

And some are used to connect to a wireless network, and these include:\u00a0nmcli<\/a>, is a command-line tool used to create, show, edit, delete, enable, and disable network connections, as well as control and display network device status.<\/p>\n

First start by checking the name of your network device using the following command. From the output of this command, the device name\/interface is\u00a0wlp1s0<\/strong>\u00a0as shown.<\/p>\n

$ iw dev<\/strong>\r\n\r\nphy#0\r\n\tInterface wlp1s0<\/strong>\r\n\t\tifindex 3\r\n\t\twdev 0x1\r\n\t\taddr 38:b1:db:7c:78:c7\r\n\t\ttype managed\r\n<\/pre>\n
Next, check the Wi-Fi device connection status using the following command.<\/p>\n
iw wlp2s0 link<\/strong>\r\n\r\nNot connected.<\/strong>\r\n<\/pre>\n
From the output above the device is not connected to any network, run the following command to scan available Wi-Fi networks.<\/center><\/p>\n
sudo iw wlp2s0 scan<\/strong>\r\n       \r\ncommand failed: Network is down (-100)<\/strong>\r\n<\/pre>\n
Considering the output of the above command, the network device\/interface is\u00a0DOWN<\/strong>, you can turn it\u00a0On<\/strong>\u00a0(UP<\/strong>) with the\u00a0ip command<\/a>\u00a0as shown.<\/p>\n
$ sudo ip link set wlp1s0 up\r\n<\/pre>\n
If you get the following error, that means your Wifi is hard blocked on Laptop or Computer.<\/p>\n
RTNETLINK answers: Operation not possible due to RF-kill\r\n<\/pre>\n
To remove or unblock you need to run the following command to solve the error.<\/p>\n
$ echo \"blacklist hp_wmi\" | sudo tee \/etc\/modprobe.d\/hp.conf\r\n$ sudo rfkill unblock all\r\n<\/pre>\n
Then try to turn\u00a0ON<\/strong>\u00a0the network device once more, and it should work this time around.<\/p>\n
$ sudo ip link set wlp1s0 up\r\n<\/pre>\n
If you know the\u00a0ESSID<\/strong>\u00a0of the Wi-Fi network you wish to connect to, move to the next step, otherwise issue the command below to scan available Wi-Fi networks again.<\/p>\n
$ sudo iw wlp1s0 scan\r\n<\/pre>\n
And lastly, connect to the wi-fi network using following command, where\u00a0Hackernet<\/strong>\u00a0(Wi-Fi network SSID) and\u00a0localhost22<\/strong>\u00a0(password\/pre-shared key).<\/p>\n
$ nmcli dev wifi connect Hackernet password localhost22<\/pre>\n
Once connected, verify your connectivity by doing a ping to an external machine and analyze the output of the ping as shown.<\/p>\n
$ ping 8.8.8.8<\/strong>\r\n\r\nPING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.\r\n64 bytes from 8.8.8.8: icmp_seq=1 ttl=48 time=61.7 ms\r\n64 bytes from 8.8.8.8: icmp_seq=2 ttl=48 time=61.5 ms\r\n64 bytes from 8.8.8.8: icmp_seq=3 ttl=48 time=61.6 ms\r\n64 bytes from 8.8.8.8: icmp_seq=4 ttl=48 time=61.3 ms\r\n64 bytes from 8.8.8.8: icmp_seq=5 ttl=48 time=63.9 ms\r\n^C\r\n--- 8.8.8.8 ping statistics ---\r\n5 packets transmitted, 5 received, 0% packet loss, time 4006ms\r\nrtt min\/avg\/max\/mdev = 61.338\/62.047\/63.928\/0.950 ms\r\n<\/pre>\n
That\u2019s It! I hope this article helped you to setup your\u00a0Wi-Fi<\/strong>\u00a0network from the Linux command line.<\/p>\n
