Cannot turn on wireless

English Network/Internet
1

Just got a new system (Linux 3.1.9-1.4-desktop x86_64, penSUSE 12.1 (x86_64), KDE: 4.7.2 (4.7.2) “release 5”) on a Sony Vaio (Intel(R) Core™ i5-2450M) -
installation of the system went flawlessly but I have some minor problems -
one is the wireless -
light turns on (hard switch) but I cannot tick the “enable wireless” option at network manager (every time I do it, it unticks itself)

here is some additional info

hwinfo --wlan --short
network:                                                        
  wlan0                Intel WiFi Link 100 Series

/usr/sbin/rfkill list
0: sony-wifi: Wireless LAN
        Soft blocked: no
        Hard blocked: no
1: acer-wireless: Wireless LAN
        Soft blocked: yes
        Hard blocked: no
2: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: no

Does ‘sudo /usr/sbin/rfkill unblock all’ change that soft block?

tried that, it didn’t change anything -

/usr/sbin/rfkill list
0: acer-wireless: Wireless LAN
        Soft blocked: yes
        Hard blocked: no
1: sony-wifi: Wireless LAN
        Soft blocked: no
        Hard blocked: no
2: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: no

what is really the acer-wireless? I am not sure I understand!

I think it arises in the acer-wmi module. Does lsmod show it loaded?

lsmod revealed that acer_wmi was loaded, and actually was the 1st wireless driver loaded -
I just blacklisted this module (blacklist acer_wmi @ /etc/modprobe.d/50-blacklist.conf) and the problem is solved

Is this an Acer laptop,or is it one of the Thinkpads that load acer-wmi by mistake?

a sony vaio and I believe the acer_wmi was loaded by mistake

As you do not have an Acer, loading that module is definitely a mistake.

Then this should be reported on Bugzilla as a Bug.
