QCA6174 - Atheros Wifi - Suspend and many other issues (Lenovo Miix 520)

Technical Issues and Assistance Drivers
, , ,
#1

Running Manjaro W/ Gnome on a Lenovo Miix 520 - have successfully gotten most components working (and plan on writing a bit of a write-up eventually), but am experiencing issues with WiFi.

I have followed the steps at QCA6174 Freeze After Suspend & used qwalers systemd's. These appear to be running and stopping / starting as they should prior to and after system suspend.

However, still have a stability problem - wifi will work for anywhere between one and twenty minutes before stopping again. running:sudo nmcli networking off sudo nmcli networking on
appears to resolve the problem, again only temporarily. When not working, the tray icon will usually show that the connection is still active or connected, but with a question mark.

When running the networking on function I will usually get an error along the lines of (process:6926): GLib-GIO-WARNING **: 16:12:49.008: ../glib/gio/gdbusobjectmanagerclient.c:1589: Processing InterfaceRemoved signal for path /org/freedesktop/NetworkManager/ActiveConnection/9 but no object proxy exists - this error has shown for ActiveConnections 4,5, and 9.

Please let me know if I can provide any logs to help troubleshoot - I'm very much a beginner at this stage. Any help would be much appreciated because relying on ethernet is a bit antithetical to the purpose of a tablet!

This issue is also sometimes appearing after rebooting, and will not work at startup until running sudo nmcli networking off and on.

Some logs (copying what jwalsh provided at Qualcomm Wifi suddenly not working ):

I am not sure whether it bears mentioning but I did have an initial issue with the modem being hard blocked, which I resolved with echo "blacklist ideapad-laptop" | sudo tee /etc/modprobe.d/ideapad-laptop.conf.

If you have not done so already, try disabling IPv6 in network manager (set to "ignore"). If IPv6 is already disabled try enabling it.

You could also test different driver options. This method will change the options on the fly and the settings will only last till you reboot.

Some options you could try are:

options ath10k_pci nohwcrypt=1
options ath10k_pci skip_otp=y

They can be tested like like this:

sudo modprobe -r ath10k_pci

sudo modprobe -r ath10k_core

sudo modprobe ath10k_pci skip_otp=y

Or:

sudo modprobe -r ath10k_pci
sudo modprobe -r ath10k_core
sudo modprobe ath10k_pci nohwcrypt=1

They can also be combined like this:

sudo modprobe -r ath10k_pci
sudo modprobe -r ath10k_core
sudo modprobe ath10k_pci nohwcrypt=1 skip_otp=y

If any of those driver options produce a marked improvement then the options can be made permanent with a configuration file in /etc/modprobe.d.

This could also be your Wi-Fi power saving settings causing the dropped connections. To change the power saving options, create a default-wifi-powersave-on.conf file:

sudo nano /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf

Add the following contents to the conf file:

[connection]
wifi.powersave = 0

A setting of "0" will totally disable power saving features in the WiFi adapter.

A setting of "2" or "1" will be less aggressive, but still leave powersaving enabled.

Also, if you are having issues with your adapter initializing correctly at start up that can be corrected with a full network restart script run at startup via a service or cronjob such as this:

#!/bin/bash
nmcli networking off
sudo systemctl stop NetworkManager
sudo ip link set wlp1s0 down 
sudo modprobe -r ath10k_pci
sudo modprobe -r ath10k_core
sudo modprobe ath10k_pci nohwcrypt=1 skip_otp=y
sudo ip link set wlp1s0 up
sudo rfkill unblock all
sudo systemctl start NetworkManager
nmcli networking on

This is only an example script. Customize it to the options you want.

#6

I also just found a post stating they had solved their issues with their Atheros adapter not being initialized at boot with a grub kernel boot parameter. If you are unfamiliar with this procedure be sure to research this thoroughly before you make any changes, as you do not want to make any mistakes when altering any option involved in the boot process.

The grub boot parameter that needs to be tested is:

pcie_aspm=off

After adding the boot parameter run:

sudo mkinitcpio -P
sudo update-grub

Please provide detailed feedback on on my previous suggestions as that will help all Atheros users looking for a solution to these types of issues.

Thanks @tbg - have been taking some time to test each case today.

So far, I found most stability (although still not stable) with power saving disabled (set to 0), ipv6 turned off (via Manjaro Wiki - Turn Off ipv6 ), and no changes to drivers. This worked smoothly for about 5 hours this morning before I started running in to the same problem again.

None of the driver combinations appeared to be making a marked improvement.

Any other ideas? I really appreciate the help so far, this one has really been bamboozling me. It seems that I can (rarely) achieve a stable connection for hours, but once the problem begins to arise again that connection time will rarely last for more than five minutes.

#8

Some further speculation: It does appear to be triggered when I plug in to AC, and is more or less stable on battery - does this make any sense at all?

I started encountering issues earlier only after plugging in, so rebooted with power unplugged - no issues - then on inserting charger have started experiencing the problem again. Correlation doesn't imply causation and all, but it does look like the dmesg output is still suggesting a power issue.

Also of note is that I can't see any error marking when things stop working.

#9

If you do not use Bluetooth I would suggest disabling it as a test. There are quite a few different ways to do that. If you use Bluetooth then I guess that's not really a viable option.

5 hours with a stable connection is certainly a vast improvement, so even if you can't get it completely resolved that is a drop rate that can probably be tolerated. The scripts I posted should be able to restart your connection without having to resort to a full reboot. That makes the problem far more tolerable.

Good luck with finding the other pieces to the puzzle.

#10

The battery symptom is a huge clue. Try disabling tlp.

sudo systemctl disable tlp

Restart then check your connections stability.

Disabling tlp is not a good full time solution, as it is important for proper laptop power management. If you can trace down the tlp setting causing the issue and disable that individual setting that is the best solution.

#11

Thanks tbg - it's a fairly new device so definitely discovering these quirks as I go!

Disabling TLP got me a stable connection for ~1600 seconds - have plugged and unplugged from AC, entered in and out of standby a few times, and it was happy, then seemingly randomly stopped again.

I'll have tried using wifi.powersave = 1 in /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf, And have reenabled tlp with the following modification to /etc/default/tlp:

RUNTIME_PM_BLACKLIST="01:00.0"

After toggling networking, I pulled another dmesg, which still returns:

[ 2031.876413] ath10k_pci 0000:01:00.0: failed to set PS Mode 0 for vdev 1: -11
[ 2031.876418] ath10k_pci 0000:01:00.0: failed to setup powersave: -11
[ 2031.876424] ath10k_pci 0000:01:00.0: failed to setup ps on vdev 1: -11

So I think we might be on to something with it being a power issue, but I'm not sure where to look next. Most of the errors also relate to 'vdev1' but I'm not sure what this is!

Are there any other logs that I could be pulling that might give a little bit more insight? What's happening at 1628+, etc is all after running sudo nmcli networking off and on.

#12

All TLP settings are stored in the config file /etc/default/tlp. The config file can be changed with any text editor (root privilege is needed).

Changes to the settings take effect after a reboot.

Parameters ending on _AC are effective with the power supply connected

Parameters ending on _BAT are effective when running on battery.

Parameters containing blanks must be enclosed in double quotes ("").

Have you tested the 2.4 Ghz band for stability?

#13

Have you tried that yet ^^^

Active-State Power Management (ASPM)

Much more info here:

https://wiki.archlinux.org/index.php/Power_management#Kernel_parameters

Also try these options:

sudo modprobe -r ath10k_pci
sudo modprobe -r ath10k_core
sudo modprobe ath10k_core nohwcrypt=1 skip_otp=y

You could also try:

sudo modprobe ath10k_pci irq_mode=1
#14

Thanks - just a typo re TLP, but no change.

I hadn't tried the ASPM settings, but did not have any luck on boot.

sudo modprobe ath10k_core nohwcrypt=1 skip_otp=y resulted in the modem not working at all, returning this:

I really appreciate your help so far, please let me know if I should just try a fresh install if all this troubleshooting is getting tedious!

Typo there^^^

It is not getting tedious. I enjoy troubleshooting with someone who is capable and "gets it". Did you read the Arch wiki link. There is some very good info there that might be worth testing out.

Is the 2.4 Ghz band the same issues?

Do you use bluetooth?

I do not think a reinstall is required at this point, but testing different live boot images would be a very good idea.

Try a gnome or kde boot disk and also a ManjaroWish Lxqt boot disk to see if your wifi is better on alternate DE's. If you find an improvement be sure to copy the firmware that is working to your system.

Let me know what happens.

Ha! That'll teach me to proof read. Not quite sure if I 'get it' yet, but eager to learn. I did try it with the typo corrected, the device doesn't show at all. I'll have another look at the wiki.

Bluetooth - don't need right now, but will do eventually. I'll see if there's any improvement in the meantime.
Do appear to be having the same issues with 2.4G.

I'll try a few boot disks, I did have to use an ethernet connection during install - live did not work on the GNOME distro running off of a USB.

You do not need to reinstall with an ethernet connection. Simply download the iso images on any computer with internet and burn the iso to a boot disk using etcher.

Also, I have seen this fix reputed to help with dropped connections with your adapter. In your bios change your sleep settings from S2Idle to S3 (deep).

I meant that I needed to connect to ethernet for the wireless drivers to download before I could use wifi.

Did just try downloading and installing the latest drivers from git, no improvement. Will try the BIOS settings.

  I take it you mean the firmware from kvalo.
#20

Yep, that's the one - from 4.4.1.

I just had a poke around in BIOS and don't appear to have any sleep or similar settings available to change.
