Bug Description

=== SRU Justification ===
[Impact]
Lenovo ideapad 530S-14ARR Wifi rfkill hard blocked

[Fix]
The platform in question doesn't have hardware RF switch, so quirk it
off.

[Test]
User confirm it fixes the issue.

[Regression Potential]
Minimal. This fix is limited to one specific platform.

=== Original Bug Report ===
I have Lenovo 530s laptop with Qualcomm Atheros QCA9377 802.11ac Wireless Network Adapter (rev 31).

The menu shows that wireless is off. Turning on the wireless from the menu does not do anything.

Interestingly, I have Lenovo 510s with Qualcomm Atheros QCA9377 802.11ac Wireless Network Adapter (rev 30) and it works just fine on Ubuntu.

For me, it appears as rev 30 works and rev 31 does not. Is this possible?

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1818204

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

Do you have a switch on your laptop to block bluetooth/wifi? Can you make sure it's not toggled on?

I don't think this laptop has such a block button. There is a button (F7) with airplane symbol. It does not seem to have any effect (even when used with FN key).

What I know is:

- If I boot to Windows, the wifi works there.
- Bluetooth works fine in Linux.

What can I do to get it working? Can I somehow force the system not to think it is hardware blocked?

Looks good. With this kernel, wlan works just fine. I can connect normally to the wlan networks.

rfkill now shows:
ID TYPE DEVICE SOFT HARD
 0 wlan ideapad_wlan unblocked unblocked
 1 bluetooth ideapad_bluetooth unblocked unblocked
 2 bluetooth hci0 unblocked unblocked
 3 wlan phy0 unblocked unblocked

Can I somehow switch to this new kernel in 18.04 in such a way that it keeps getting security updates?

Once the fix is in the default Bionic kernel, you can switch back to use it.

Does this need any fix in network-manager? Seems to be fully fixed by the kernel patch.

Yes it's purely a kernel bug.

Thanks. Closed network-manager tasks.

Hi,

I tested with only the patched kernel and it enables wifi.

However, there still seems to be something weird happening. Even though, the wifi seems to work, it might take from seconds to minutes for a web page to load. It feels like having a bad connection, but in a mixed way. For example, it might take long time to get into youtube and have video running, but the video then might run ok. With MS Windows, the wifi works well and there are no delays.

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-cosmic' to 'verification-done-cosmic'. If the problem still exists, change the tag 'verification-needed-cosmic' to 'verification-failed-cosmic'.

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!

Hi

How do I test the proposed patch? I enabled backports. Then did apt update & apt dist-upgrade.

My Linux version is:
Linux 530s 4.18.0-17-generic #18~18.04.1-Ubuntu SMP Fri Mar 15 15:27:12 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

ID TYPE DEVICE SOFT HARD
 0 wlan ideapad_wlan unblocked blocked
 1 bluetooth ideapad_bluetooth unblocked blocked
 2 bluetooth hci0 unblocked unblocked
 3 wlan phy0 blocked unblocked

With 4.18.0-17 the wifi is hard blocked.

Sami Pietila (sampie) wrote :

Hi,

I think I have enabled pre-released updates. Is the kernel version (4.18.0-17-generic), the one that should have this patch?

I am wondering because wifi does not seem to work with this kernel.

Thank

It should be 4.18.0-18-generic.

Sami Pietila (sampie) wrote :

Now dist-upgrade found that kernel. I can confirm, with this kernel rfkill reports the device unblocked.

I further tested this new 4.18.0-18-generic kernel and with this kernel the wifi seems to work very good. I did not observe any slowness as I did with the patched 4.18.0-16 kernel.
