Help, because without internet, Ubuntu is useless. I can't enable wireless. My physical switch is on, it's working in windows, but I just can't enable wireless. I updated my drivers, and when I goto turn the wireless switch on, I click on, but it immediatley goes back to off. So I turned off airplane mode, but it still goes immediatley back off. Please help, immediately!

we love to help you - but we need more useful information in your question! run in a terminal sudo lshw -class network and rfkill list all and copy and paste the output into your question. Add the version of ubuntu you are using to your question as well. – fossfreedom Nov 9 '11 at 22:32

I have foud this solution:

sudo gedit /etc/modprobe.d/blacklist.conf

Add a line at the very end:

blacklist acer_wmi

sudo gedit /etc/rc.local

Add one line above "exit 0":

rfkill unblock all
