[ubuntu] No audio, no wifi, Ubuntu 14.04LTS

Hello,

After an update and reboot, my laptop doesn't recognize any wireless conection, only wired, and haven't sound neither.

After reeding some issues from help assistance about sounds troubleshooting, it seems my laptop doesn't have a proper driver to the sound card installed (i really dont understand why, before update everything was fine and functional)

About the wireless conection problem, I've tried some solutions found on internet, but no succeed.

Here are some hardware specifications:

After running "nm-tool"

I really hope someone can help me.
