Exclamation "Wireless is disabled" even with killswitch off


I recently junked my old Dell Studio laptop and bought a new Lenovo IdeaPad S10 netbook. The WLAN device is Atheros AR9285. The problem I'm facing is that in Ubuntu Netbook Remix 10.04, Network Manager shows "Wireless is disabled".

Code:
lshw -C network
...shows my WLAN device to be disabled. I checked that WiFi is enabled in BIOS, and also toggled the physical radio killswitch on/off but no luck.

Output for rfkill list shows
Code:
0: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: yes
...even though wireless has been enabled with the hardware switch. I've tried the usual routine of booting up with wireless enabled from hardware, booting up with wireless disabled then enabling it without success.

Also, I don't whether this is important, but no proprietary driver is listed under hardware drivers. I'm assuming this will easily be rectified once the device is detected.

Would really appreciate some help regarding this!

The Atheros AR9285 chip set is supported by the ath9k driver. I have the same chip set in my HP mini. It works just fine.

Open a konsole, and run the command 'lsmod | grep ath9k' ( all commands without the quotes ) and see if the driver is loaded.

If not, then see if you have it installed. On my system it is located here: /lib/modules/2.6.32-21-generic/kernel/drivers/net/wireless/ath/ath9k/ath9k.ko

I'm running Ubuntu 10.04 as well.

If it is not loaded, try 'modprobe ath9k.ko' and see if it will load. If it loads, then you will need to configure it, and then activate it.

Hope this helps.

A few more things that I tried

On the advice of a friend on Twitter, I tried another thing.

1. Opened up '/var/lib/NetworkManager/NetworkManager.state'. 'Wireless' was set to 'false', so I changed that to true.
2. Restarted NetworkManager with

Code:
sudo /etc/init.d/network-manager restart
This did restart the Network Manager, but the wireless is still disabled. On inspecting the Network Manager state file, I found that the value for wireless had again been set to false.

Help, please?

Hi Cliff, thanks for that suggestion! ath9k shows up on grep, and the module that you mention is on my system too at the same path. However, when I try modprobe, I get this error:

Code:
FATAL: Module ath9k.ko not found.

To modprobe a module, you have to proceed it with sudo ( and supply the root password ). However, if the driver is loaded, there is no need to load it again.

Have a look at System--> Preferences--> Network Connections and click the Wireless tab. Is the SSID you are trying to connect to there? If not, try click the Add button and fill in the correct information. Then try to add the information. At the bottom there is a check box for 'Available to all users' Check that, click apply, then try to activate your connection. If you have a router, then Mode should be 'Infrastructure'.

Give it a try and see how far you get.

check bios vga controller settings

This could be a problem with handling interrupts.

My son's new ASUS ul80jt also uses the AR9285 chipset... At first it seemed like wifi worked, as it found networks with "iwlist wlan0 scan" and it connected and was able to obtain ip address. But after a random interim of being up, a message appeared in dmesg "Disabling IRQ #17" and the entire wlan0 interface would disappear.

It was the same story with wicd. Once the IRQ was got disabled, the interface was no longer available.

I tried blacklisting ipv6 since I don't use it. But this did not solve it.

I tried upgrading to the most recent kernel, which at the time of this posting, was 2.6.35.5, so I could have the most recent ath9, and this too did not solve the problem, though it seemed like signal strength increased while it was up before the crash. At least inteface would come back after a reboot.

Then, looking over the bios setup I noticed a setting for the vga controller to be set for windows or to be set for other os. I changed this setting to the "other os" setting, and upon reboot, the wifi has worked flawlessly for over a day now.

I think the vga controller setting in the bios affected the IRQ handling.

Maybe it is the same on your bios.

Thanks Cliff, for so patiently trying to solve my problem. I did use sudo modprobe the first time round, and got the error.

As of now it's not detecting any wireless networks, so the SSID is not shown by network manager. I manually entered the SSID, but it didn't help as wireless is still shown as disabled.

I did some searching on this issue and came across a post in on Ubuntu Forums that seem promising. http://ubuntu-virginia.ubuntuforums.....php?p=8500132 So I installed 'linux-backports-modules-wireless-lucid-generic' (along the lines suggested in that thread) and reboot my computer, but that didn't work either,=.

Then I tried out the instructions at https://help.ubuntu.com/community/Wi...Atheros/AR9285 After following the instructions there and rebooting, Network Manager doesn't show anlyy status for wireless, i.e., it only lists wired connections now.

So I tried lshw -C network again, and here's the output I got:

Code:
  *-network UNCLAIMED
       description: Network controller
       product: AR9285 Wireless Network Adapter (PCI-Express)
       vendor: Atheros Communications Inc.
       physical id: 0
       bus info: pci@0000:09:00.0
       version: 01

       capabilities: pm msi pciexpress bus_master cap_list
       configuration: latency=0
       resources: memory:f0100000-f010ffff
The device, which is now listed as 'UNCLAIMED' was previously (before the manual make/install process) listed as 'DISABLED'. When I try 'rfkill list', 'lsmod | grep ath9k' etc now, I get no results.

The last step on Ubuntu Docs was 'sudo make unload', so I tried 'sudo make load' after the wireless device was not detected after rebooting. I again got a list of errors related to ath9k:

Thanks! I checked my BIOS settings again, and there seems to be no option for VGA controllers. There's just one for wireless - and that is enabled. I tried disabling, saving, then re-enabling after a reboot but that didn't work.

don't include the .ko when using modprobe

Quote:
If it is not loaded, try 'modprobe ath9k.ko' and see if it will load
Try leaving off the ".ko" when using modprobe, and just call the kernel modules by it's name, without the extension.

What happens when you try:
Code:
sudo modprobe ath9k
?

Thanks. I tried that, and it results in errors:

I don't have access to a Windows system right now, but I'll try to see if the Windows driver works with ndiswrapper. Would rather prefer to see the native driver working but ndiswrapper is worth a shot. (I downloaded the Windows driver. Extraction of .exe - to get the driver file - with 'unzip' fails for some reason.)

NDISWRAPPER? WHAT? I'm sure it works through the wrapper, but there would be a decrease in performance... and it's like giving up and allowing proprietary code on your system. However, there are enough instances of AR9285 working under linux (like on son's laptop) that I'm sure you will win if you keep up your good effort...


Code:
WARNING: Error inserting ath9k_hw (/lib/modules/2.6.32-24-generic/updates/drivers/net/wireless/ath/ath9k/ath9k_hw.ko): Unknown symbol in module, or unknown parameter (see dmesg)
WARNING: Error inserting ath9k_common (/lib/modules/2.6.32-24-generic/updates/drivers/net/wireless/ath/ath9k/ath9k_common.ko): Unknown symbol in module, or unknown parameter (see dmesg)
FATAL: Error inserting ath9k (/lib/modules/2.6.32-24-generic/updates/drivers/net/wireless/ath/ath9k/ath9k.ko): Unknown symbol in module, or unknown parameter (see dmesg)
You should ensure that ath9k_common.ko and ath9k_hw.ko are available to your kernel.

My son's laptop reveals this:
Code:
prompt% ls /lib/modules/2.6.35.5/kernel/drivers/net/wireless/ath/ath9k

ath9k.ko    ath9k_common.ko     ath9k_hw.ko
Your ath9k installation is probably identical, except the version number of the kernel will be whatever version is on your system...

If the ath9k_common.ko and ath9k_hw.ko are missing, then mystery solved. If they are present, then I would try to get them updated. Either way, get the ath9k drivers from compat-wireless, which allows you install newer drivers on older kernels, or get them by updating your kernel completely.

Greatquizzard,

I agree, avoid ndiswrapper if at all possible. This card should work with the ath9k kernel module.

Thought I would show what lsmod looks like on a working system.

Quote:
lsmod | grep ath9k
ath9k 306010 0
mac80211 205146 1 ath9k
ath 7611 1 ath9k
cfg80211 126517 3 ath9k,mac80211,ath
led_class 2864 1 ath9k
Is this what you see if you list the ath9k module? Or is one of the other modules on the left side not showing up?

Any way to boot your system from a live CD? Or memory stick? 10.04 comes with the correct modules. It would be nice to see if a clean install or live boot would work. If it does, you could decide to do a clean install as a way out.

This is the card I have:

Quote:
02:00.0 Network controller: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01)
Is yours the same rev 01 level?

Thanks slac-in-the-box, Cliff. My Ubuntu was showing the ath9k module till yesterday, but now it isn't! I'll try a clean install and see if that helps.

I reinstalled Ubuntu, tried compat-wireless, but nothing works! BTW, rfkill still shows wlan0 has hard-blocked. What do I do? :|

Just an update - in the end, I had to install Windows 7 to activate wireless from the killswitch, then installed Ubuntu again. Everything works perfectly now!
