Ubuntu 12.04 WIFI Issue

Many times the "WIFI in" my Thinkpad R61 could is not work after start up, however, it would work and after rebooting. I Googled this issue, but just got following the "Askubuntu". Unfortunately, there is no solution to this problem yet.

BTW, I learned such Linux commands the "I":

Iwconfig
sudo ifconfig wlan0 up
sudo rfkill list all
sudo rfkill unblock all
sudo lshw-class network

Ubuntu 12.04 Wifi Problem atheros Communications Inc AR9285 Wireless Network

Hi Ask Ubuntu my wireless isn't working so this is my info:system Using:lenovo Z570

$ iwconfig

Lo        no wireless extensions.

Wlan0     IEEE 802.11bgn  essid:off/any  
          mode:managed  Access point:not-associated   Tx-power=off   
          retry  long limit:7   RTS thr:off   Fragment thr:off power
          management:off

eth0      No Wireless extensions.

$ sudo ifconfig

$ sudo ifconfig wlan0 up

Siocsifflags:operation not possible due to Rf-kill

Now when I use this:

$ sudo rfkill list all

1:phy0:wireless LAN
    Soft blocked:no
    Hard blocked:yes
2:ideapad_bluetooth:bluetooth
    Soft blocked:no
    Hard blocked:no
4:hci0:bluetooth
    Soft blocked:no
    Hard

Then I use command:

$ sudo rfkill unblock all

Then:

$ sudo rfkill list all

1:phy0:wireless LAN
    Soft blocked:no
    Hard blocked:yes
2:ideapad_bluetooth:bluetooth
    Soft blocked:no
    Hard blocked:no
4:hci0:bluetooth
    Soft blocked:no
    Hard

Here phy0 Hard blocked = yes

Result is the same (then I again try to switch on/off Wi-Fi from keyboard by pressing FN+F5)

$ sudo rfkill list all

1:phy0:wireless LAN
    Soft blocked:yes
    Hard blocked:yes
2:ideapad_bluetooth:bluetooth
    Soft Blocked:no
    Hard blocked:no
4:hci0:bluetooth
    Soft blocked:no Hard blocked:no
    

Now this time phy0 Soft blocked = yes as as A/hard blocked:yes

This is hardwares specs:
