Debian 9.4.0: Wi-Fi networks: device not managed.

Postby stf92 » 2018-05-30 13:38

Hi: I have just installed the ISO image firmware-9.4.0-i386-netinst.iso, which contains non-free propietary drivers needed by the wi-fi controller in this machine. After installation I booted and placing the mouse cursor over the network icon it says "No network connection". Clicking I read:
Code: Select all
Wi-Fi networks:
    device not managed

What does it mean? The installer itself had no problems using the Internet.

I usually see that on network-manager when a device is hard/soft blocked by a switch or rfkill, or when the device is listed in /etc/network/interfaces, or when the device is set to unmanaged by .conf file somewhere in /etc/NetworkManager

I guess there could be other reasons that it is unmanaged, the best way to find out is probably to read some documentation.

If you are not using networkmanager, then read the documentation for whatever gui tool you installed, or try some websearches.

Well, thanks very much. In the meanwhile I have found a solution in Google: in /etc/NetworkManager/NetworkManager.conf I replace line 'managed=false' by 'managed=true', I rebooted and had Internet at once. But yours is also mentioned in Google. And thanks for the link.
