@Laks,

I’m glad you found the tutorial helpful!

It seems like the issue you’re encountering with nmcli could be related to the network manager not recognizing your WiFi device properly. Even though you can see the WiFi interface wlp3s0 and scan for networks using sudo iw wlp1s0 scan, nmcli might not be detecting it correctly.

Here are a few steps you can try to resolve this issue:

sudo systemctl restart NetworkManager
systemctl status NetworkManager
nmcli device
sudo dpkg-reconfigure NetworkManager
sudo lshw -C network

However, the last step using nmcli to connect to my WiFi network is failing with the error message “Error: No Wi-Fi device found“.

If there is no WiFi device, how was I able to complete all the other steps as you mentioned? I even used the command sudo iw wlp1s0 scan which listed all the WiFi networks and their related status information.

The desktop originally had WiFi when it was running Windows, but it was removed when Windows 7 became outdated and CentOS v7 was installed.

$ iw dev

your interface is wlp1s0

Why in the holy world are you using:

$ iw wlp2s0 link
