How to solve Device Not Managed in kali ( Debian ) Linux

Kali is based on Debian—that’s why I titled it “Kali (Debian)“. If you’re trying to use a new network card or connect to a physical network, this problem can occur. At first glance, it simply looks like NetworkManager isn’t detecting the new interface.

You can simply solve this by following these steps:

Steps

Open the /etc/NetworkManager/NetworkManager.conf file in any text editor (I’m using nano):
```
sudo nano /etc/NetworkManager/NetworkManager.conf
```
Change managed=false to managed=true

NetworkManager configuration file showing managed=true

Restart NetworkManager:

sudo systemctl restart NetworkManager

Note: On older systems, you might need to use:

sudo /etc/init.d/network-manager restart

Done

Now verify it’s working.
