Re: networkmanager can not enable wireless scanning

Thanks Larry for your help.
iwconfig shows a wireless device.
here is my output :

this dmesg -c output is the only output when i click the 'enable
wireless' button(of course, it automaticly unchecked again. :( )
[root localhost]/home/codedancer# dmesg -c
[  434.786071] IPv6: ADDRCONF(NETDEV_UP): wlp3s0: link is not ready

And other command output is below, thanks .

Hi list,
When I click 'enable wireless', nm will automaticly uncheck the button
before 'enable wireless'.
Even if I try to boot with  ubuntu 13.04 livecd , it still cannot
enable wireless.

Please help me , thanks .
if you need more info, just let me know.

Two things that suppress wireless come to mind.

Does iwconfig show a wireless device? If not, you may be missing the
necessary firmware. Check the output of dmesg to see if there are any
messages regarding missing firmware.

Does "rfkill list" show anything blocked?
