Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

Without myself modifing any configuration setting, my system starts to completely freeze after I activate the wifi network via the network manager or at a sudo rfkill unblock all.

I would like to kindly ask for your assistance as I do not understand how to fix it.

Thanks in advance for your help!

Here's my system information:

In gnome-system-log I cannot find a thing. The powermanagement did not change things either. How do I know which is the correct kernel module?

I am really lost.

Hi, can you capture the system log (run gnome-system-log and try to replicate the issue, then note down what logs that may come up)? Hopefully your system would have time to log events when your problem happens. –  oaskamay Mar 13 '13 at 23:21
    
I had a problem with my network driver causing kernel panic on 64-bit systems. Maybe this answer will help. –  butla Apr 25 at 21:02

1 Answer 1

I'm suspecting that the issue here is related with wireless power management.

Please try running this command: sudo touch /etc/pm/power.d/wireless. Then try to reproduce your issue.

It'll remove the execution bits of the file wireless which is executed whenever the power manager does its work with wireless interfaces.
