Ubuntu 12.04 Wireless unmanaged



When installing Ubuntu, and during install You choose to use wlan0 interface.
On first system boot wireless becomes unmanaged, and You can’t choose wireless AP.

solution is to edit file /etc/network/interfaces
There should be lines like

auto wlan0
iface wlan0 inet dhcp
   wpa-ssid wifi-name
   wpa-psk wifi-key

delete those lines and reboot computer. Network manager will be able to control wifi.

    It is superb! It works on my laptop wifi which had been become “unmanaged” since I have turned it as a hotspot access point and I forgot how did I do that. Thanks alot!!!!

  2. This one really worked!! Thanks from a Linux n00b.

  3. Unbelievable. This is great. Is this a bug? Maybe someone should tell them so this could be fixed. I can’t see a situation where this would benefit someone, except maybe as a security feature.
