I have an Acer Aspire One D257 notebook I installed Ubuntu 12.10 on. Everything worked until I allowed the automatic updates to be installed. It appears that applying the updates breaks the wireless network adapter on this machine. It reports "Network device not managed".
The regular Ubuntu flavour was too slow anyway, so I tried Lubuntu 12.10 (Live) and discovered it was really faster than Ubuntu. I then decided to install it with automatic updates and after the first reboot the Wi-Fi network did not work anymore, similar to my attempt with Ubuntu.
Any idea on how to fix this? I'd like to be able to keep my system up to date.
