168c:002b [Asus U32U] asus_nb_wmi AR9285 ath9k not working after updating to Ubuntu 13.04 Raring

[pixolex]

update: updated the BIOS to the latest version but the problem persists.

Booting with the older kernel (latest linux kernel from 12.10) every thing works fine. After upgrading to Raring Ringtail Ubuntu 13.04, with the new kernel, hardware get blocked/disabled and wireless doesn't work:
0: phy0: Wireless LAN
 Soft blocked: no
 Hard blocked: yes
1: asus-wlan: Wireless LAN
 Soft blocked: no
 Hard blocked: no

WORKAROUND - is only applicable to Asus Notebooks/netbooks that use the "asus_nb_wmi" driver:
Create and edit asus_nb_wmi.conf file with this command:
sudo echo "options asus_nb_wmi wapf=4" | sudo tee /etc/modprobe.d/asus_nb_wmi.conf

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.9 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

[pixolex (pixolex)]

The new kernel (v3.9-raring) doesn't totally fixed the bug, some times it works, some times it doesn't work.

When it works:
- the wi-fi led stays off after boot;
- the wi-fi led simply doesn't work even if I use Fn-F2 or sudo rfkill block/unblock all, but the interface connects and disconnects form my wi-fi router;
- rfkill list shows just one interface:
1: phy0: Wireless LAN
 Soft blocked: no
 Hard blocked: no

When it doesn't work:
- the wi-fi led is on after boot;
- the wi-fi led turns on and off if I use Fn-F2 key or sudo rfkill block/unblock all;
- rfkill shows two interfaces:
0: phy0: Wireless LAN
 Soft blocked: no
 Hard blocked: yes
1: asus-wlan: Wireless LAN
 Soft blocked: no
 Hard blocked: no

I'm trying to find why it randomly works, if there's any sequence of restart/shutdown that makes it work.

I think the bug is not fixed, and I'm marking it as "kernel-bug-exists-upstream"

[penalvch (penalvch)]

pixolex, as per https://www.asus.com/Notebooks_Ultrabooks/U32U/#support_Download_30 an update is available for your BIOS (208). If you update to this, does it change anything?

As well, once updated, please provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

Thank you for your understanding.

[pixolex (pixolex)]

I had already updated the BIOS to the latest firmware. I reported that in the first line of the bug report.

So here is the output of the command line as asked:

U32U.208

[Heiner Wohner (hewo)]

My Notebook(Acer Aspire S3) was affected by this bug, too. I resolved it by downgrading the kernel to 3.6.11.

You can download it under:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.6.11-raring/

Maybe you have to load the driver with 'modprobe ath9k nohwcrypt=1', because of another older bug.

Good luck.

[penalvch (penalvch)]

pixolex, thank you for providing the requested information. Could you please test the latest upstream kernel available (v3.10-rc2) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the kernel in the mainline kernels archive directory daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.10-rc2

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags:
kernel-unable-to-test-upstream
kernel-unable-to-test-upstream-VERSION-NUMBER

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.

[pixolex (pixolex)]

No news with linux kernel v3.10-rc5
Exactly the same random problem. If the wireless led turns on during boot sequence no wireless, if it keeps off during boot sequence I got wireless working.

[penalvch (penalvch)]

pixolex, thank you for performing the requested test. Could you please commit bisect this following https://wiki.ubuntu.com/Kernel/KernelBisection ?

[pixolex (pixolex)]

I've tested the linux-image-3.11.0-999-generic version, but no luck.

I can't bisect.

[penalvch (penalvch)]

pixolex, could you please test the latest released mainline kernel (not the daily) via http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.11-rc7-saucy/ and report the results?

[pixolex (pixolex)]

linux-headers-3.11.0-031100rc7-generic_3.11.0-031100rc7.201308252135_amd64.deb
linux-headers-3.11.0-031100rc7_3.11.0-031100rc7.201308252135_all.deb
linux-image-3.11.0-031100rc7-generic_3.11.0-031100rc7.201308252135_amd64.deb

I've instaled the latest kernel version you indicated and got this warnigs:

W: Possible missing firmware /lib/firmware/rtl_nic/rtl8168g-3.fw for module r8169
W: Possible missing firmware /lib/firmware/rtl_nic/rtl8106e-2.fw for module r8169
W: Possible missing firmware /lib/firmware/rtl_nic/rtl8411-2.fw for module r8169

After some test an a lot of reboots and shutdowns i've concluded that now wfi simply does't work. Not even the led works any more.

[penalvch (penalvch)]

Pixolex, latest mainline kernel is now http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.11-saucy/ . Could you please test with this and advise on the results?

[pixolex (pixolex)]

No luck, no change, exactly the same problem: Wireless is dead!

0: asus-wlan: Wireless LAN
 Soft blocked: no
 Hard blocked: no
1: phy0: Wireless LAN
 Soft blocked: no
 Hard blocked: yes

I think I'll have another 6 month period with a old kernel, since saucy e coming. Worst, I'll not have video decoding acceleration in hardware with a old kernel.

What can I do more without bisect?

[gmax.jp (gmax-jp)]

I have EeePC 1001HA(wlan is AR9285) and troubled with same problem for a couple of these days.
If you are running dual boot system, try reboot from windows and enable your wlan then reboot ubuntu again.
This works for me.

I also found phy0 is hard blocked all the time while the problem occurs and enabling wlan on windows unblocks this.

# rfkill list
0: asus-wlan: Wireless LAN
        Soft blocked: no
        Hard blocked: no
1: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: yes

After enabling wlan on windows, rfkill reported that pyh0 was unblocked.

# rfkill list
0: asus-wlan: Wireless LAN
        Soft blocked: no
        Hard blocked: no
1: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: no

That's why some of cases regarding this defect looks like "randomly happened".

BTW I've occasionally seen similar problems caused by other wlan device such as realtek drivers...kind of typical problem? ;)

Hope this helps a bit.

Cheers,
Max

[pixolex (pixolex)]

I've just found the problem!!!

And the problem is....... THE MODULE: "asus_nb_wmi"

After blacklist the asus_nb_wmi module the "0: asus-wlan: Wireless LAN" is gone from rfkill list and wireless works again!!!

sudo rfkill list all
0: phy0: Wireless LAN
 Soft blocked: no
 Hard blocked: no

The collateral damages are that the "Fn" keys are gone also, since this module is for that.

In this mail (http://lwn.net/Articles/429993/) we can read: "I hope this series won't break anything, because there are a lot of change."

Is Mr. Corentin Chary the "father" of this bug?

[pixolex (pixolex)]

How to solve/workaround the problem without the collateral damages until someone "QUIRK" this bug with a U32U "wapf" patch to http://lxr.free-electrons.com/source/drivers/platform/x86/asus-nb-wmi.c

a) If you blacklisted the asus_nb_wmi module, please UNblacklist it

b)Create and edit asus_nb_wmi.conf file with this command: sudo echo "options asus_nb_wmi wapf=1" | sudo tee /etc/modprobe.d/asus_nb_wmi.conf

c)reboot

Just for the record:
This bug is present in recent UBUNTU 13.10, since is a LINUX KERNEL BUG.

[penalvch (penalvch)]

pixolex, could you please undo any WORKAROUNDs, and test the latest mainline kernel via http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.12-rc6-saucy/ ?

[pixolex (pixolex)]

No luck with 3.12-rc6-saucy (3.12.0-031200rc6-generic).

The bug persists, but the workaround persists too. ;)

[penalvch (penalvch)]

pixolex, getting back to https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1173681/comments/16 , any reason specifically why you couldn't bisect? This would be the most helpful way forward in getting this bug addressed.

[pixolex (pixolex)]

OK, I'll try to biscet, but you have to help me.

Where do I start?

[penalvch (penalvch)]

pixolex, since we know this regression was going from Quantal to Raring, you would want to bisect Ubuntu kernel versions as documented in https://wiki.ubuntu.com/Kernel/KernelBisection#Bisecting_Ubuntu_kernel_versions .

[pixolex (pixolex)]

Well, I know the first non working kernel that I tested, it's the linux 3.8.0-19-generic link in the title of the bug report , but I don't know the last Quantal kernel. I remenber it was 3.5.xx something.

Can you help me?

[varunendra (varunendra)]

Not promoting the "WORKAROUND" here, but as long as people coming to this page have to resort to it, I've re-written it in a cleaner and more comprehensive manner in this thread : http://ubuntuforums.org/showthread.php?t=2181558
(also includes how to quickly & completely revert back)

Post #1 in it contains the symptoms, verification, and the workaround, and post #2 contains a workaround for the Fn+F2 key disability.

Also, this workaround is LIMITED to *ASUS* Notebooks/Netbooks ONLY.

I myself have an Asus X54C, but haven't upgraded from kernel 3.2.0-36 yet, so not affected yet. (a 500+ download will take about 2-3 frustrating days on my snail pace gprs connection that breaks every few hours).

Would be more than happy to do the bisecting and other requested operations as soon as I upgrade.

As a side note, I think there should be a separate bug report against "asus_nb_wmi" driver as this one addresses a problem that can be caused by other reasons on other models too. Have requested the same in the linked thread too.

[varunendra (varunendra)]

@adam,

If it is not a UEFI based installation, try a BIOS reset (to factory defaults). Or, if it is dual-booting with Windows 8, try a hot-reboot while the wifi is active.

If these don't help, I suggest you start a thread at ubuntuforums.org with the description of the problem and the wireless_script report, and post its link here so we can follow. This may not be a good place for the kind of troubleshooting you may have to go through.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-utopic' to 'verification-done-utopic'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

This patch is just a quirk with a very low chance of regression.

[kidmis (kislitsyn-dmytro)]

Christopher,

I wasn't able to create report using ubuntu-bug, so I'm going to post the details here.

I have the same laptop as Stanislav - K501UX, wireless Intel 7265:
sudo lspci -vk -s 03:00.0
03:00.0 Network controller: Intel Corporation Wireless 7265 (rev 59)
 Subsystem: Intel Corporation Dual Band Wireless-AC 7265
 Flags: bus master, fast devsel, latency 0, IRQ 129
 Memory at df100000 (64-bit, non-prefetchable) [size=8K]
 Capabilities: [c8] Power Management version 3
 Capabilities: [d0] MSI: Enable+ Count=1/1 Maskable- 64bit+
 Capabilities: [40] Express Endpoint, MSI 00
 Capabilities: [100] Advanced Error Reporting
 Capabilities: [140] Device Serial Number 10-02-b5-ff-ff-57-26-fa
 Capabilities: [14c] Latency Tolerance Reporting
 Capabilities: [154] L1 PM Substates
 Kernel driver in use: iwlwifi
 Kernel modules: iwlwifi

Kernel:
4.4.0-13-generic

My symptoms:
Wi-Fi is hard blocked by default and LED airplane mode is on. Fn+F2 doesn't do anything in this case since it works on soft level (not hard, if I'm correct).

Solution:
The trick with adding "options asus_nb_wmi wapf=4" or wapf=1 fix the issue partially. In my case I got worked Wi-fi device, but LED airplane mode shows wrong status (when wifi is off - it's on, and vice versa).

Is there something I can fix or so?
