I am currently using Ubuntu 12.04 and for the second time in a week, Ubuntu freezes completely, becoming entirely unresponsive. The only way to use it again is to turn off the power to reboot.

Both times the same thing happened. All of the sudden, the wireless connection to the Internet is lost, ubuntu keeps trying to connect and asks for password and some seconds later then it freezes.

I don't understand why the wireless connection fails, since it works fine after I reboot PC and I am close enough to router, I never had wireless problem on Windows 7 for example.

This is a serious issue because I have no chance of saving work.

Any ideas on why this is happening?

I just checked and my Graphics Controller supports Unity 3D. I don't think it has to do with Unity 3D, although I can try use gnome for a while and see what happens... – Neptunno Jun 10 '12 at 20:09

Dear first of all you should check if your wireless device driver is activated or not.

You can check it from "ADDITIONAL DRIVERS"

If it's activated then check for driver update first.

Then at last update your ubuntu 12.04 for latest security updates and bug solutions.

You will surely can come out of this problem. Good Luck. :) & Don't Forget to vote up! :)

Additional Drivers utility just looks for them and then states that "the system is not using proprietary drivers". I update Ubuntu pratically everyday, and in between both crashes I surely did updates... So they brought nothing new about this issue. – Neptunno Jun 10 '12 at 18:03
