lenovo wifi disabled broadcom

[amalnath]

hi,
Im using natty in lenovo b460. After installation was not able to connect to wifi. Ethernet is working alright.
So searched for additional drivers and installed the Broadcom 43xx drivers. After restart the network applet says the wireless is disabled by hardware switch, even after it is switched on/off several times.
Lenovo B460
kernel:2.6.38-8-generic 32-bit
Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller (rev 01)
ubuntu 11.04

tried "sudo rfkill list".
The output is
0: ideapad_wlan: Wireless LAN
Soft blocked: no
Hard blocked: no
1: ideapad_bluetooth: Bluetooth
Soft blocked: no
Hard blocked: no
2: acer-wireless: Wireless LAN
Soft blocked: yes
Hard blocked: no
4: brcmwl-0: Wireless LAN
Soft blocked: no
Hard blocked: yes
6: hci0: Bluetooth
Soft blocked: no
Hard blocked: no..
any help is appreciated....:sad:

Please open a terminal and do:
sudo rmmod -f acer-wmi
sudo rfkill unblock all
rfkill list allAre you now able to use the wireless? If so, we can tweak one file and make it persistent.
