Can't turn on WIFI on Lenovo z580 using Fn+F5

Question

I can't turn my wireless adapter on using the network settings it says wireless is disabled by wireless switch. On my computer the hardware switch is Fn+F5. When I press it nothing happens. Anyone have any idea how to fix this problem?

I found out my hard ware witch although it doesn’t do any thing works fine. when I do

# rfkill list

I get

0: phy0: Wireless LAN
    Soft blocked: yes
    Hard blocked: yes
1: ideapad_wlan: Wireless LAN
    Soft blocked: yes
    Hard blocked: no
2: ideapad_bluetooth: Bluetooth
    Soft blocked: no
    Hard blocked: no
3: hci0: Bluetooth
    Soft blocked: yes
    Hard blocked: no

then I pressed Fn + F5 and did

# rfkill list

And got the below result

0: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: yes
1: ideapad_wlan: Wireless LAN
    Soft blocked: no
    Hard blocked: no
2: ideapad_bluetooth: Bluetooth
    Soft blocked: no
    Hard blocked: no
3: hci0: Bluetooth
    Soft blocked: yes
    Hard blocked: no

that proves that the key combination works. I checked my BIOS too wlan is enabled.

And # sudo lshw -class network gave me

Please see: http://askubuntu.com/questions/14008/i-have-a-hardware-detection-problem-what-logs-do-i-need-to-look-into then edit your question and include here any useful info. — NickTux, Feb 22 '13 at 22:27
Probably we will need more info. Include the results of the following commands lspci -nnk | grep -iA2 net and lsmod and lsb_release -rcd — NickTux, Feb 23 '13 at 23:06
Please [edit] this question to change hard ware witch to hardware which so that online language translators can work properly. — mickmackusa, Nov 15 '21 at 05:49

first, you can check in the system settings if the key combinations Fn + F5 is correctly assign. depending on your computer specs, some key combinations may be not assigned.

you can go in the system settings, keyboard (in hardware section), shortcuts, and assign it from there (if needed).

other way, you can install xdotool

sudo apt-get install xdotool

and config it from there.

xbindkeys is a third alternative.

Try these commands

sudo modprobe -rvf ideapad-laptop
sudo modprobe -rvf ath3k 
sudo modprobe -rvf ath9k

Then

sudo modprobe ath9k

Wait for 10 secs and..

...Check again the results of rfkill list all before and after the Fn+F5

See if your wireless is up and running now. It seems to me like a mess up with ideapad-laptop module , see modinfo ideapad-laptop from more.

Also for some reason , 2 modules of atheros are loaded. ath3k and ath9k. You need only the ath9k.

Above commands will unload the modules and re-load only the ath9k.

If this works , maybe you need to unload the module every time you boot your PC. An entry in /etc/rc.local maybe help.

Try to set in BIOS configuration page , the NET device as first on boot order. – NickTux Feb 25 '13 at 01:48
what returns "modinfo ath9k" ? may be you have to disable hardware encryption, like explained here : http://ubuntuforums.org/showthread.php?t=1781350&page=2 – riimzzai Feb 25 '13 at 19:32
through trial and error I got 0: ideapad_wlan: Wireless LAN Soft blocked: no Hard blocked: no 1: ideapad_bluetooth: Bluetooth Soft blocked: yes Hard blocked: no 2: hci0: Bluetooth Soft blocked: no Hard blocked: no now i dot get a wireless option in my network settings – crm881125-n Feb 27 '13 at 04:20

I solved it on Lenovo B570 by reseting the BIOS (after several tries). Turn on the computer, get into the BIOS with F2 key and reset it with F9 key.

Hope it helps!
