WiFi hardware blocked. RFkill not working.

Hello everyone!

I have an Atheros AR9285 chip in my laptop. My problem is that I can't turn it ON. I would appreciate if anyone know where should I look for, or what to do. So here is my troubleshooting and information:

Just installed Kali Linux 1.0.2 amd64 with Gnome, so I see that my wifi is not on.

System Settings --> Network
- Airplane is On, turned it off.
- Ethernet is On.
- Wifi is Off, can't turn it On.

Code:

root@kali:~# lspci 00:1f.2 SATA controller: Intel Corporation 7 Series Chipset Family 6-port SATA Controller [AHCI mode] (rev 04) 00:1f.3 SMBus: Intel Corporation 7 Series/C210 Series Chipset Family SMBus Controller (rev 04) 01:00.0 Network controller: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01) 02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8101E/RTL8102E PCI Express Fast Ethernet controller (rev 05) 03:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd. RTS5229 PCI Express Card Reader (rev 01)

* I intentionally shortened the output of lspci.

Code:

root@kali:~# iwconfig wlan1 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 Encryption key:off Power Management:on eth0 no wireless extensions. lo no wireless extensions.

So I try ifconfig and see it's down,

Code:

root@kali:~# ifconfig wlan1 up SIOCSIFFLAGS: Operation not possible due to RF-kill

Now with these error, after a quick search, the obvious solution everywhere is to use rfkill.

Code:

root@kali:~# rfkill list 0: phy0: Wireless LAN Soft blocked: no Hard blocked: yes root@kali:~# rfkill unblock all root@kali:~# rfkill list 0: phy0: Wireless LAN Soft blocked: no Hard blocked: yes

I tried with "rfkill unblock wifi" and even in some forums someone said that unplugging the laptop and taking off the battery worked. (?).

So these are the modules,

Tried removing hp_wmi and wmi, they are related to sitching the state of the wifi with a key (link), but didn't worked.

The output of dmesg is quite long so here is some selected output,

If want the complete output of dmesg, just ask and I'll post it. Any Ideas??

Thanks

Hard blocked, means you need to find a (physical) switch to turn on the hardware. On my note book it would be the Fn Key + F12.

This was how i fixed it on my laptop:

Applications Menu > System Tools > Preferences > System Settings

ok Now from here I opened "Network" and while the window is open I could see that my "Airplane Mode" switch was toggled on AND PERSISTENTLY ON.

Toggle Airplane OFF and while the window is still open and in place, PRESS YOUR PHYSICAL STANDBY/POWER BUTTON

The system will go to standby. Now resume the system and toggle your wifi button. It seems there is a glitch in the system. who would have thought >:D.

Sorry for late answer, I thought my question didn't make it through moderation.

I still struggle with this problem so it's kind of killing my productivity. It was as Cod says, the "airplane mode" was persistently ON..(sigh..) And toogling the Wifi button didn't work.

Last week I moved on and change my Mini-PCI wifi card for the one that came originally with the laptop. A Broadcom 4313. Which does function well automatically on Kali Linux. (not on Debian though).

I really can't bealive how I'm struggling with this for WEEKS, so frustrating. The driver brcmacsm works fairly well on kali but not on Debian (useless). Really astonishing. And a well supported chip card Atheros can even turn wifi ON??

Objectively it's a bug that came with the hardware I think. But it was out of my hands.

Thanks.

hi all,

i am having issues enabling wireless in Kali/Debian.

I tried the following;
1) reset to BIOS default
2) rfkill unblock all
3) pressed Fn + F2 (Gateway Notebook, T-Series)
4) same behaviour with other wirless USB devices.

not sure what else to do, still searching! any help would be appreciated.

thanks

First, makesure you do sudo rfkill disable all and then sudo ifconfig wlan0 up first justo be sure that's not going to be the issue.

Ok now go to the Applications drop down menu, then to system tools, then preferences, then System Settings. In here towards the bottom there is a Network icon. Click it to open your network settings and go to your wireless connections tab where you see that "Airplane Mode" is stuck on. Ok now toggle it off AND THEN STOP EVERYTHIG YOU ARE DOING--- and leave the network settings window open. With everything as-is, go up to the power menu and put the system on standby. Wait a few seconds for your computer to sleep. Now just move the mouse to wake it up and then hit the "enable wifi" switch/ button in the wifi control panel and hit your hardware wifi toggle key combo and it should all stick. I have done this with three different wifi cards, 2 atheros and one Broadcom. I also saw this problem with a standard Ubuntu installation on another computer. You may need to repeat this process again in the future.

Hi everybody, first of all i want to say sorry if i not make myself clear **** muy english is really bad.
I just install Kali and I`m struggling with the same issue that idetuxs, my Laptop it`s a Toshiba LS515 and i turn off the wirelles by th combination of fn+F8, But did it wen i was running windows 7. So I reboot, load Windows 7 turn on the wifi, reboot again and now works perfectly, I don`t now why. If somone knows why please let me know.
Just wanna add that the laptop dosen`t have a physical switch.
Thanks!!!

I ran into this problem earlier today and was able to solve it by booting into Windows and enabling Wifi via a keyboard shortcut as my laptop doesn't have a physical switch to enable and disable the wireless adapter. When I enabled the adapter within Windows, the Wifi light came on and booting into Kali, everything worked fine.

This problem has been raised by us before you will have to search old blogs. We like Aeon in the above thread have found that some laptops must have their wifi devices enabled by windows. Even external usb wifi devices will not function unless the internal wifi is first switched on and left on. If you turn the manual switch off everything stops functioning and you have to go to windows, turn the system back on then reboot to kali-linux. Note we use xp/linux dual boot. We have four lap tops and each reacts differently but the general theme remains the same. So if you have a manual switch do not switch it off. But there is more.

Next is Network Manager(two small computers) - Upper righthand corner of screen

Make sure Enable Wireless is checked and Enable Networking is checked

Be careful with Network Manager. If you are having problems enabling your wifi devices NEVER remove the check next to Enable Wireless. This will kill your wifi devices. Clicking on Enable Wireless may NOT reenable the devices. You may have to go thru the windows routine again.

You can remove the check next to Enable networking though.

You will find Net Work Manager now constantly intruding. So if you do not need Networking remove the check next to Enable Networking and your screen will thank you.

I solved the problem. And turned to open the BIOS default settings. After improving.

Here is a Solution Guys!!

I have Still the Same Problem that when i Boot Kali 2.0, my WIFI is Hardware blocked. (NO its not the **** switch on my laptop)
>> What you need to do is Turn your Laptop or Computer in Hibernate modus or sleep modus. Wake him UP an your WIFI should work. <<

Would really love to see a FIX for this because i have this issue since Kali 1.0.x.

Since you are experiencing this since kali1.0 we suggest you try the following as MTeams have two laptops just like this. You need to turn your wifi ON thru windows. Once windows turns on the wifi software the rf-kill will disappear. Your wifi firmware may require windows to activate it. Turning the on/off switch will not correct this. If you dig thru these forums you will find one of our postings on this. If you have an internal wifi receiver get that functioning thru windows first then shutdown and boot into kali and do not ever turn the wifi power switch off again.

THX for the help, i deleted Windows. But your post should help many other peopl whit that Problem. (should pin this post somewhere where its easier to find.)

Requiring Linux users to use Windows is not an acceptable solution. Windows is only software, anything it can do can be done through Linux, we just need to find out how. :) Of course, if hw manufacturers would cooperate by providing full specs, it would be much simpler.

I found a solution to make the computer not recognize the the hardware block thus making it never be hardware blocked.

I was having and am still working with a wireless problem. My network card would become hard blocked after I attempted to use macchanger.

Code:

ifconfig wlan0 down && macchanger -A wlan0 && ifconfig wlan0 up

When the interface was put back up, my computer would think I was in airplane mode because it was hardblocked. rfkill unblock all was not doing anything for me. I found a post that helped me to prevent the hard block. I still can not however connect to a network using network manager. It just keeps searching and never finds a network. I also attempted to connect through the command line with no success whatsoever. PLEASE HELP ME!

See if this helps you buddy.

Check the value of a parameter -

Code:

cat /sys/module/ath9k/parameters/no_hw_rfkill_switch

If it is set to "N", try this -

Code:

echo "options ath9k no_hw_rfkill_switch=Y" | sudo tee /etc/modprobe.d/ath5k.conf

This will create a conf file for ath9k driver, which apparently tells the driver to "Ignore" the hardware switch's rfkill state. Enable the wifi with rfkill command and reboot to see if it remains on. If it (the conf file) causes the opposite effect, simply delete the file -

Code:

sudo rm /etc/modprobe.d/ath9k.conf

..and reboot to return to current state.

Solution is very simple TRY ONCE

restart your OS and when it prompt to add password check upper right corner if wifi is still hardware disabled or not.

if it show hardware disabled just click your hardware button to ON ...and it will work
then type PASSWORD and check..

how i followed this process-
1. ON Airplane mode
2. restart OS
3. when password is prompted click hardware wifi switch on keyboard to ON wifi.
4. login to system it will work
