Xiaobian to share with you how to use the Nmgli command to connect WiFi in Linux terminals, I believe most people still do not know how, so share this article for everyone's reference, I hope you have a lot of harvest after reading this article, let's go to understand it together!

The nmcl command is a command after redhat7 or centos7. This command can complete all configuration work on the network card, and can be written to the configuration file and take effect permanently.

First check the name of the network device using the following command. From the output of this command, the device name/interface is wlp1s0, as shown.

$ iw devphy#0Interface wlp1s0ifindex 3wdev 0x1addr 38:b1:db:7c:78:c7type managed

Next, check the Wi-Fi device connection status using the following command.

iw wlp2s0 linkNot connected.

The output from the top of the device is not connected to any network, run the following command to scan for available Wi-Fi networks.

sudo iw wlp2s0 scancommand failed: Network is down (-100)

Considering the output of the above command, the network device/interface is in the DOWN state and you can turn it ON (UP) using the ip command as shown in the figure.

$ sudo ip link set wlp1s0 up

If the following error occurs, it means that your Wifi is hard to block on your laptop or computer.

RTNETLINK answers: Operation not possible due to RF-kill

To remove or unblock, you need to run the following command to resolve the error.

$ echo "blacklist hp_wmi" | sudo tee /etc/modprobe.d/hp.conf$ sudo rfkill unblock all

Then try turning on the network device again, and this time it should work.

$ sudo ip link set wlp1s0 up

If you know the ESSID of the Wi-Fi network you want to connect to, go to the next step, otherwise issue the following command to scan for available Wi-Fi networks again.

$ sudo iw wlp1s0 scan

Finally, connect to the Wi-Fi network using the following commands, where Hackernet (Wi-Fi network SSID) and localhost22 (password/pre-shared key).

$ nmcli dev wifi connect Hackernet password localhost22

Once connected, verify the connection by ping the external computer and analyzing the ping output as shown.

$ ping 8.8.8.8PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.64 bytes from 8.8.8.8: icmp_seq=1 ttl=48 time=61.7 ms64 bytes from 8.8.8.8: icmp_seq=2 ttl=48 time=61.5 ms64 bytes from 8.8.8.8: icmp_seq=3 ttl=48 time=61.6 ms64 bytes from 8.8.8.8: icmp_seq=4 ttl=48 time=61.3 ms64 bytes from 8.8.8.8: icmp_seq=5 ttl=48 time=63.9 ms^C--- 8.8.8.8 ping statistics ---5 packets transmitted, 5 received, 0% packet loss, time 4006msrtt min/avg/max/mdev = 61.338/62.047/63.928/0.950 ms
