Perfect — let’s fix this “unmanaged” Wi-Fi issue step by step. Since editing NetworkManager.conf didn’t work, we’ll explicitly tell NetworkManager to manage wlan0.

==== NetworkManager won’t manage any interface defined in /etc/network/interfaces. Run: ====

<syntaxhighlight lang="bash">cat /etc/network/interfaces

</syntaxhighlight>

If you see something like:

<syntaxhighlight>auto wlan0
iface wlan0 inet dhcp

</syntaxhighlight>

then NetworkManager will ignore it.

✅ Fix: Comment out or remove wlan0 from this file:

<syntaxhighlight lang="bash">sudo nano /etc/network/interfaces

</syntaxhighlight>

Change to:

<syntaxhighlight lang="text">#auto wlan0
#iface wlan0 inet dhcp

</syntaxhighlight>

Save and exit.

==== Check /etc/NetworkManager/NetworkManager.conf again: ====

<syntaxhighlight lang="bash">sudo nano /etc/NetworkManager/NetworkManager.conf

</syntaxhighlight>

Make sure you have:

<syntaxhighlight>[ifupdown]
managed=true

</syntaxhighlight>

If you added it before, leave it.

==== <syntaxhighlight lang="bash">sudo systemctl restart NetworkManager ====

</syntaxhighlight>

==== <syntaxhighlight lang="bash">nmcli device status ====

</syntaxhighlight>
* wlan0 should now appear as disconnected, not unmanaged.

==== <syntaxhighlight lang="bash">sudo ip link set wlan0 up ====

</syntaxhighlight>

==== <syntaxhighlight lang="bash">nmcli device wifi rescan ====
nmcli device wifi list

</syntaxhighlight>

You should now see your networks.

===== If you just want to get online without changing config files, you can manually create a NetworkManager connection: =====

<syntaxhighlight lang="bash">sudo nmcli dev set wlan0 managed yes

</syntaxhighlight>

Then try scanning again:

<syntaxhighlight lang="bash">nmcli device wifi rescan
nmcli device wifi list

</syntaxhighlight>

This command forces NM to manage wlan0 for the current session.

If you want, I can give a full one-shot set of commands that usually fixes “unmanaged” Wi-Fi permanently on Kali, Raspbian, or similar minimal distros. It’s like a shortcut that gets you online fast.

Do you want me to do that?
