wireless - How to unblock something listed in rfkill? - Ask Ubuntu


i think may have found cause of problems connecting wifi in ubuntu 11.10.

i type in terminal:

peter@peter-ao531h:~$ rfkill list 0: phy0: wireless lan     soft blocked: no     hard blocked: yes 1: acer-wireless: wireless lan     soft blocked: yes     hard blocked: no peter@peter-ao531h:~$ rfkill unblock peter@peter-ao531h:~$

if correct must unblock of "yes", right? nothing happens when try unblock. typing wrong command?

typing "sudo modprobe -r acer_wmi" seem have added problem, can't try click on "enable wireless"-button has been grayed out , "1: acer-wireless: wireless lan" not show anymore in rfkill list. have idea how fix that?

edit: rebooted , not grayed out anymore , rfkill list shows as:

0: phy0: wireless lan     soft blocked: no     hard blocked: no 1: acer-wireless: wireless lan     soft blocked: yes     hard blocked: no

the 0 not hard blocked anymore, guess 1 needs put off soft blocked somehow.

"hard blocked" cannot changed software, wifi toggle on keyboard or edges of laptop; device can hard blocked if disabled in bios.

"soft blocked" means "blocked software". faulty driver or other kernel module can lead connectivity loss.

some methods wifi working described on help.ubuntu.com/

there launchpad question on issue: answers.launchpad.net
