Bug Description

Binary package hint: linux-image-2.6.32-21-generic

I have installed Ubuntu from CD [Ubuntu-Netbook 10.04 _Lucid Lynx_ - Beta i386 (20100318)] Wireless has been detected automatically and everything worked fine.

One day after installing updates on the 26.04.2010, i noticed that after Booting the Wireless interface and bluetooth is disabled, regardless of the wireless switch.
It seems that the switch is turned off, regardless if the switch is on or off, even Fn-F5 (Software-Switch for Wireless/Bluetooth) does not help.

WORKAROUND: After a suspend and wake, do:
sudo rmmod ath9k
sudo modprobe ath9k

Then wireless is available and connects automatically. Bluetooth is also available. Everything works fine then.

But when booting the kernel from power off, the wireless led is on when grub is shown and gets turned off, when the kernel boots and both, Wlan and Bluetooth are disabled.
When Wlan is working and I turn off the wireless hardware switch, Wlan and Bluetooth gets disabled as expected, but when I turn it on again, it does not get reactivated and I have to do the workaround again to get it working again.

I don't think that it is defective hardware, because:
  * Before the problem appeared the first time, everything was working fine.
  * After doing the workaround, everything works fine
  * The wlan led is on in the grub menu, but it turns off, when the kernel is loaded.

Hi Michael,

Please be sure to confirm this issue exists with the latest development release of Ubuntu. ISO CD images are available from http://cdimage.ubuntu.com/releases/ . If the issue remains, please run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 577114

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

Reloading modules (my previous comment) works only after suspending and waking up the system.
When the system is booted from power off, wireless is turned off and reloading the module does not help to reenable wireless.
When the system is restored from suspend, wireless remains turned on, dmesg shows "ath9k: Unable to set channel" messages and reloading the ath9k module helps to get wireless working.

Today I have installed the current updates (stable), but this didn't solve the problem.

It was even worse, because the workaround using suspend/wakeup and reloading the ath9k module didn't work.

I didn't get wireless to start working. The wireless LED was always turned off immediately after beginning boot/wake up.

Then I tried again with the stable kernel:

dmesg-2.6.32-22-generic - dmesg just after boot, no wireless available, wireless led is off.
dmesg-2.6.32-22-generic-reload-ath9k - Reloaded module ath9k, still no wireless available, wireless led is off.
dmesg-2.6.32-22-generic-suspend-wakeup - after suspend/wakeup, wireless led stays on, but wireless still unusable.
dmesg-2.6.32-22-generic-suspend-wakeup-reload-ath9k - Reloaded module ath9k, wireless connects and works fine.

With the stable kernel I can enable wireless by suspend/wakeup and reloading the ath9k module.

Michael Mess (michael-michaelmess) wrote :

I have blacklisted the ath9k module for testing.

The result is the following:
  * The wireless-LED gets turned off when booting, and stays turned on on wakeup, as before.
  * After boot wireless does not work after modprobe.
  * After wakeup wireless works after modprobe (rmmod is not necessary because the module was not loaded).

Thus we can conclude:
  * The wireless led is not turned off by loading the ath9k module, the fault must be somewhere else.
  * When loading the wireless module on wakeup it just works; when it was not blacklisted and is already loaded, it is somehow broken. This might be caused by interference with something else on wakeup.

Soft-Blocking and unblocking works as expected, but the Wireless-LED stays on, but I didn't turn off Bluetooth, so that it makes sense when it stays on.

After boot it says "Hard blocked: yes" - but the hardware switch should not block the device as it is in position "((([])))" and i didn't change it when suspending and waking up after which it was working.

When installing an own kernel I forgot to create the initrd.img file in /boot and thus I have noticed something interesting.

When booting, I saw that in grub menu the wireless LED was still on.

Then I selected the new kernel and got a kernel panic ("Kernel panic - not syncing : VFS : Unable to mount root fs on unknown-block(0,0)") because the initrd.img was missing - and then, what is interesting here, I saw that the wireless LED was already off!

Thus the LED and thus likely the wireless hardware has been turned off before mounting the initrd.img.

After fixing the problem and booting the new kernel, the wireless didn't work and I had to apply the suspend workaround.

I was able to reproduce the kernel-panic problem by just renaming the initrd.img file and saw that the wireless LED has already been turned off when the kernel panic occurs.

Chase Douglas (chasedouglas) wrote :

The hardblock says there is something in the machine that is turning the wifi off, but it's not something the operating system can control. Seeing the hardblock turn on when you flip the physical switch is correct behavior, but when it stays blocked when you flip it back means there is probably a bios bug. I would check your bios setup to ensure it doesn't have the wifi disabled.

Hello,

I would like to confirm that I also have this exact same problem in every respect (exact same device and OS). I have followed and duplicated each and every step of this thread and I have had exactly the same experience in every respect. Does anyone have any update on this condition that can be shared? I have numerous Lenovo S10-3 netbooks in a wireless environment running UNR 10.04 and two of the devices have developed this condition with no permanent workaround or fix discovered. Reinstall of OS does nothing at all. Condition exists even when booting directly from live USB of OS. Any further information would be greatly appreciated.

First I'd like to thank Michael for his workaround. Works perfect every time though a real pain to have to go through to get wireless working.

So I've got the same issue but a slightly different experience. In my case, the issue didn't appear until I disabled wireless using the switch on the side of the laptop. I had been running 10.04 (first install was beta) on the netbook since taking delivery in March without issue. A few weeks ago I used the unit at work and disabled wireless via the switch to avoid setting off our IDS. Later that evening I sat down in my living room to do some reading and found myself in the same situation as everyone who's contributed to this thread. After some degree of searching I came across this thread and voila, problem solved.. though not to the level of service I had previously known of the S10-3.

Today I had some time and revisited the issue. My findings agree with the theory posed by Chase. This does appear to be a bios bug triggered by activation (or deactivation as it would have it) of the wireless switch on the side of the case. Appears there is a persistent setting that gets flagged in the bios when the switch is moved to off that doesn't get cleared when moved back to on. With a little bit of work and a small Phillips and a small flat screwdriver this issue can be solved.

I only post this as a guide of the actions I took to resolve this issue and in NO WAY, SHAPE or FORM am I responsible for your actions.
****************************WARNING******************************

The instructions below involve removing the battery backup power for your BIOS to allow a complete reset to factory settings. When complete you will need to reset any customized settings you may have made to the BIOS.

Move wireless switch into ON position

1. Turn the laptop over (bottom up) and remove the battery
2. Remove the 6 black screws around the outer edge of the case
3. Remove the 3 silver screws under the battery
4. Turn the unit back over (top up) open the screen
5. Using the small flat screwdriver, wedge it between the top edge of the function keys and the case. With the 3 silver screws removed, there are small plastic tabs in the top corners of the keyboard that snap in place. Gently pry the keyboard up along the top edge. You will hear an audible pop as the tabs disengage.
6. Gently tilt the top edge of the keyboard toward you. There are small tabs on the bottom edge of the keyboard which insert into the case to hold it in place.
7. The keyboard is attached to the motherboard via ribbon cable. There is enough cable that you can flip the keyboard over and still get to the connector.
8. Using your fingernail, you can pry up the lock on the connector which holds the ribbon cable in place.

Thank you for the bios fix idea. I like the superglue on the wireless switch! I am going to use that one!

The workaround I used to reactivate the wireless permanently was to reimage the hard drive back to the original Windows 7 installation. I was then able to reactivate the wireless using the Windows 7 troubleshooting wizard along with the Fn-F5 key combination. Once the wireless was active, I reinstalled Ubuntu and everything is working fine. I agree that the condition will happen again under the right conditions. Though this is not a permanent fix on its own, gluing the switch in the ON position should prevent it from recurring.

Thanks for your description how to open the netbook to reset the CMOS
RAM by removing the battery and the report that it solves the issue.

This proves that there is a BIOS bug that
  * writes something like a lock when the switch is turned off.
  * does not release the lock when the switch is turned on again.

Maybe there is a utility which can be used to erase the CMOS RAM using
Linux without the need to open the cover each time when the problem occurs.

I hope that Lenovo will bring out a bootable CDROM image which can be
used to update the BIOS to a newer version where the bug is fixed and
which also has a function to clear the CMOS RAM by overwriting its content.

After suspending and resuming multiple time after using the workaround, I found myself with a read-only root file system after some errors have occured.

I was only able to login at text console to save the logs, X11 didn't restart after I have logged out when it was behaving strange.
Before logging out I noticed that firefox didn't start correctly (it gave an empty window and was hanging) and before that I had to kill the screen saver from the text console to get access to X11.

Maybe this could be related and others suffering from this bug may also have suffered from that, thus I am posting it here.

I'm having this problem also. I just upgraded to 10.04 from 9.10 through System Update, i386 version on a Toshiba Satellite using an Atheros card. In my case, cutting wireless off manually does successfully work, but attempting to cut it back on from the switch fails. Additionally, using rfkill unblock doesn't work. 9.10 didn't have this issue for me, so I'd wager this is a 10.04 issue with the BIOS, if anything.

Just my two cents.

Thanks for workarounds. I use Lenovo S10-3 with Intel 5150 WiFi/WiMAX card and have this issue too.

Manually i found tip with suspend (works fine without loading/unloading any modules on this model, just only suspend/resume operations). BIOS reseting was new to me and works fine too.

Also, suspend workaround dont enable wireless led, but BIOS resetting does.

When I did a "dmesg" I saw lots of these "ath9k: Unable to set channel" message in the log, then I reloaded the module and everything was fine.

So it seems that the problem after the workaround which requires a module reload is limited to setting the channel.
To avoid this problem and making the required module reload obsolete, maybe the ath9k driver could try to reinitialize the functionality to set the channel when setting the channel fails or when waking up from suspend.

Today I am testing with a self compiled kernel with boot delay support compiled in.
I booted the kernel with the kernel parameters added: earlyprintk=vga boot_delay=1000
Then I watched the lines coming up one by one during boot and watched the WLAN-LED:

{{{
bio: create slab <bio-0> at 0
}}}
Then the WLAN-LED gone off.
{{{
ACPI: Interpreter enabled.
}}}

Thus It seems that the WLAN-LED turns off during ACPI initialization.

I too have this bug, and have seen it happen on two different hardware revisions of the ideapad S10-3. One has a broadcom wireless chipset and one is the newest revision, 06472BU with combination bluetooth/atheros wifi chipset. Play with the wireless switch too much and it will show up in rfkill under linux as being hard blocked, and the bluetooth doesn't appear at all. However, I found a couple ways of working around this. One is via removing the CMOS battery as shown above, and another involves having the laptop dual-boot Windows (I have Win7 32-bit on mine) and using the "Lenovo Energy Management" utility available here:

http://consumersupport.lenovo.com/ot/en/DriversDownLoads/Drivers_Show_2362.html

Pressing fn-F5 with this utility installed brings up a wireless switch with separate on/off settings for WiFi and Bluetooth - and toggling them to "ON" in Windows also makes them work again in Linux. Now, someone with more skill and motivation than me might go and look at this utility in a debugger and see exactly what it is doing, whether it is doing something ACPI-related or poking some register.
Just thought I'd offer this up as a starting point for developers.

I'm not a Ubuntu user (gentoo instead), but I came across this thread while researching this same problem that you all have experienced. In hindsight it seems obvious, but instead of wiping the BIOS memory by unscrewing everything and unplugging the battery - just reset the BIOS back to its default settings.

Reboot -> F2 -> F9 (load default BIOS settings) -> F10 (save & exit)

Worked for me.

I have a Lenovo S10-3 netbook and can confirm the bug. I dual boot Kubuntu and Meego, and the wireless issue occurred in both OS at the same time, so I suspected a hardware/BIOS bug right away. Seems that the experience of fellow users here and elsewhere have confirmed this.

I first tried to make sure the wireless switch on the left side of the case was enabled, tried to reset the BIOS to defaults in the BIOS setups screens ... BUT, I could not get wifi enabled. "rfkill list" always showed hardware blocking. I tried resetting the BIOS settings many times, with the hardware switch in both positions (just in case there was an incorrect toggle orientation or something). No luck.

Lenovo release a BIOS update, but that route was un-appetizing because (1) it required windows, and (2) I was too risk averse to run it under WINE (yikes) and was not willing to install windows 7 just to attempt a risky-anyway BIOS flash.

I ended up just biting the bullet and removing the bunches of screws necessary to get at the CMOS battery. This worked. I wish there was another way, but for me, this was the only alternative to installing windows to fix the problem. As involved as it is, it saves a lot of time installing win, then re-installing linux.

I can never get phy0 off hard blocked.

Interestingly, when I disable the bluetooth and wifi switch, hci0 disappears from rfkill list, but phy0 stays.

I cannot wake from suspend, this has been a long running issue, so consequently I cannot try the workaround.

same as sean, I removed the CMOS battery, and although this fixed the LED, which had broken at the same time as the wireless, phy0 is still obstinantly hardblocked.

5) The wirelles wi-fi and bluetooth was turned OFF. I turned it ON.

6) Reboot on Linux. The step 5) made wi-fi and bluetooth becomes avaiable under ubuntu and other distros I was having trouble (fedora has
the same issue)

7) The wirelless hard-switch are functional and can be used with no problems.

I guess the management application is changing some bios configuration under windows and reflecting it on Linux where we dont have a way to FIX. I left a windows partition in case I need to change this for some reason.

Guilherme's comment (#66) is confirmed to be a working solution to this issue. I too had the same issue on my Lenovo Ideapad S10-3 netbook. I first took the netbook apart to reset the CMOS as posted above in another fix but once booted in either Windows 7 or Ubuntu 11.04 , the wireless card would not work.

After installing the Windows 7 Broadcom Wireless LAN Driver and the Lenovo Energy Management driver, I rebooted (just as a good measure) and went back into windows and hit fn + f5 and selected "turn on".
By default, when the above drivers are installed, it may appear that the problem still exists which is where you will need to use the Fn + f5 to turn it back on.

After which I then booted into Ubuntu 11.04 and confirmed that the wireless did in fact work there as well.

You can show the bios version, which is currently installed, by typing:

The current bios version which is available from Lenovo is: 2ACN37WW

Did anybody encounter these problems with bios version 2ACN37WW?
Is this a good BIOS version or does it still have some annoying bugs?

Any experiences with BIOS versions between 2ACN21WW and the newest available one are also highly appreciated.

Some people reported success with the "Reboot -> F2 -> F9 (load default BIOS settings) -> F10 (save & exit)" workaround.
With which bios version did that work?

I am currently looking for a way how to safely upgrade the BIOS without the need to install Windows.

The first thing I am going to try is to backup the currently installed BIOS.
Reading the BIOS image is unlikely to brick my netbook, but it is a first test, if accessing the BIOS image works well.

My first tries using a BartPE CD were not successful, because the WinPhlash utility shipped with the 2ACN37WW.exe file (MD5SUM: c510bc34109684289e8ec30079b6916c) from Lenovo could not find a file and exited.

If anybody here has a backup of 2ACN21WW, saved from WinPhlash started from Windows, please simply report the MD5SUM of the backup file.
This would be beneficial because then I could compare it with my results when I got a backup.

If that succeeds, I will consider to try upgrading to the newest version.

Hi everybody,

More than one year has elapsed and Lenovo still neither brought a fix nor gave any feedback about that bug.

Current available bios is still 2ACN37WW from 2010-10-25 which does not solve the issue.

Therefore I invite everybody who is affected to motivate Lenovo to bring a fix for the issue:

 * Let Lenovo know about it: There are several ways to do so:
   * Use the feedback forms on the support page
   * Call lenovo support
   * Open a support ticket, if you have a lenovo support contract
   * You can submit a link to this ticket, this will give lenovo technicians important information to find the bug and solve it.
 * Use the "Affects me too" function in Launchpad.
   * Maybe Lenovo will have a look at this page and they wouldn't take this bug so seriously if only few people seem to be affected.

As there is no fix from Lenovo, maybe we can write a driver which can turn on WLAN in the CMOS-RAM.
To do that, we need more information about where the WLAN-flag is stored in the CMOS-RAM,
so let's gain more information about what is stored in the CMOS-RAM.

To do that, everybody's help is appreciated.
We need to collect nvram images of several laptops
and try to isolate the bytes responsible for activating/deactivating WLAN.
Thus it is beneficial if many people do these steps and attach their files with the additional information.

The CMOS-RAM is also called nvram and it's content can be read using the Linux nvram driver.
Some detailed information can be also found there:

http://www.pixelbeat.org/docs/bios/

To get more information of what is stored in the nvram,
we have to collect nvram images of several laptops, with the following state:

 - WLAN works normally.
 - WLAN does not work, but workaround works.
 - WLAN does not work at all.

Each nvram image should have information which bios version is installed,
as the information stored in the nvram might vary depending on the BIOS version.

To get an nvram image, you need the nvram driver which is part of the Linux kernel
and can be loaded as module.
When the module is loaded, there is a file /proc/driver/nvram which can easily be read.

To get the BIOS version installed in that laptop:

michael@ideapad:/proc/driver$ sudo dmidecode -s bios-version
[sudo] password for michael:
2ACN21WW

As you now have the nvram driver loaded, you can create an nvram image:

michael@ideapad:/proc/driver$ cp nvram ~/nvram-2ACN21WW-2012-06-28-wlan-working-after-workaround.nvram

I am not sure whether this is a bug in ubuntu per-se.

I had switched off wireless using the side switch, but could never enable it back via toggling the switch.

Ultimately, i rebooted using "lenovo quick start" (the "QS" button on the lower right side of the screen), and was simply able to enable wifi back using the config option. Rebooted back in ubuntu and the wifi was working fine again.

If you dont have "quick start", you could try booting under windows and using the fn+f5 to re-enable wifi.

After long time I am happy now, because I surprisingly found a workaround that fixed this issue for me, with neither opening the case nor using/installing any proprietary software like Windows, etc.

I booted with a KALI-Linux Live-CD to try to recover some lost pictures from an IPhone that got deactivated because the children entered a wrong passcode too often...

Then KALI-Linux told me that the Airplane mode is on and I should use the hardware switch to turn it on.
Thus I turned it off and on again, the same procedure which was useless for so long time with ubuntu.
When I turned the switch on again, there was some disc activity and suddenly Wireless LAN started working again and I could connect to WLAN.

After some unsuccessful tries with the IPhone :-( I was leaving KALI-Linux and booting from hard disk again, and found: Wireless LAN is still working! :-)

Then I stored the nvram and compared with and old nvram image: They both have the same size and MD5sum.
Thus the information if the hardware switch is on or off seems to be stored somewhere else, but not in the area used for nvram.
Probably the flash memory available is bigger than the area used for nvram and the information is stored somewhere else.

As KALI Linux is Open-Source, it is very likely that it is possible to find a solution for Ubuntu and to try out what turns Wireless on or off.

Here is a small HOWTO howto fix the issue: (I wrote it very detailled, so that almost everybody that finds this here can use it)

 - Download Kali Linux: https://www.kali.org/ and download directory is http://cdimage.kali.org/kali-2016.1/

wget http://cdimage.kali.org/kali-2016.1/kali-linux-2016.1-amd64.iso
wget http://cdimage.kali.org/kali-2016.1/SHA1SUMS
wget http://cdimage.kali.org/kali-2016.1/SHA1SUMS.gpg

 - Check that your download is not corrupt and is authentic

gpg --verify SHA1SUMS.gpg SHA1SUMS

The output should be as follows:
gpg: Unterschrift vom Mi 20 Jan 2016 21:37:00 CET mittels RSA-Schlüssel ID 7D8D0BF6
gpg: Korrekte Unterschrift von »Kali Linux Repository <email address hidden>«
gpg: WARNUNG: Dieser Schlüssel trägt keine vertrauenswürdige Signatur!
gpg: Es gibt keinen Hinweis, daß die Signatur wirklich dem vorgeblichen Besitzer gehört.
Haupt-Fingerabdruck = 44C6 513A 8E4F B3D3 0875 F758 ED44 4FF0 7D8D 0BF6

Now you know that the SHA1SUMS file has been signed with the key, but you still cannot trust the key.
Compare the fingerprint with the one listed on https://www.kali.org/downloads/ and check the https// certificate.
If you trust the https// certificate an the finger print there equals the one from gpg --verify, then you can trust the key used for the signature and the signed file.
Now you need to check the file against the trusted SHA1SUM

sha1sum -c SHA1SUMS

The output should be as follows:
kali-linux-2016.1-amd64.iso: OK
...

If you didn't download all the other files mentioned in the SHA1SUM file, SHA1SUM will complain about the other files, but that can be igored.
The SHA1SUM of the file should be: deaa41c5c8f26b7854cafb34b6f1b567871c4875 kali-linux-2016.1-amd64.iso

Now you can be quite sure that you got an authentic copy of KALI-Linux and can write it onto a DV...

Note:
the kali-linux-2016.1-amd64.iso image is 2,8G big and won't fit on a CD.
So you need to take a DVD to write it on, even if I wrote CD somewhere in the text above.
