@elkamynante,

It sounds like your Wi-Fi issue might be related to missing drivers or power management settings.

Here are a few things you can try:

1. The command $ iw dev is part of the iw package, you can install it by running:

sudo apt update && sudo apt install iw

After installing, try running $ iw dev again to check if your Wi-Fi adapter is recognized.

I’m a completely new user of Mint (completely = zero knowledge in my brain). I’ve installed Cinnamon on a new SSD using the Dual Drive Dual Boot Method, totally separate from Windows, disconnecting all other SSDs on my PC.

I have an internet connection, but it is very weak (35%) with frequent disconnections all day long and slow browsing most of the time. When I type in the Terminal: $ iw dev, I receive “command not found“.

Furthermore, I have no idea what to do :-) I’m searching for advice on whether it is possible to get my internet speed to match what I have in Windows. I use a Wi-Fi connection from a Wi-Fi 6 router with a 600MB symmetric optical fiber connection.

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The desktop originally had WiFi when it was running Windows, but it was removed when Windows 7 became outdated and CentOS v7 was installed.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