Wifi droping on Qualcomm Atheros QCA9377

sojuz151 · 2020-04-04 18:33:49

When punting wife under stress by speed testing or file downloading it randomly crashes. Happens only on 5GHz( tested phone hotspot on 2.4 GHz with no crash) . It can be fixed by forcing nmctl to reconnect to Wifi Network. I use lenovo S340-14IPS, no problems under windows.

Ping during typical crash:

Please wrap those outputs in [ code ] [ /code ] tags without the spaces.

You could try disabling hardware encryption (hwcrypto=0 module option) or disable power saving:

# iw dev wlp2s0 set power_save off

^ If that works make a udev rule to set it permanently: https://wiki.archlinux.org/index.php/Po … interfaces ← that rule enables power saving so invert the boolean for your case.

But I had one of those cards in my ThinkPad and it ran *very* hot and degraded in performance over time so it might be best to just replace it. I'm using an Intel AC 9260 now, which only cost £20 and performs faultlessly.

EDIT: you have recurrent coredumps from KDE's activity manager in that log, might be worth investigating (but probably unrelated to your network issue).

So i tired

sudo modprobe  ath10k_core nohwcrypt=1 skip_otp=y hwcrypto=0
sudo modprobe  ath10k_pci nohwcrypt=1 skip_otp=y hwcrypto=0

nohwcrypt=1 skip_otp=y are other options i have seen being suggested online. Unfortunate neither of thous modules seems to understated no hardware encryption.

From what i seen on other forums Lenovo has a wiki card whitelist. It can be bypassed by dumping bios and editing it in IDA Pro what is not a great solution.
Enabling power saving did not help. I still get crashes. Will try to cannibalize wifi card from old laptop, it did work well with Linux.

You can find the options a module supports with

modinfo modulename

Edit:
For the ath10k it should be
cryptmode=1 https://github.com/torvalds/linux/blob/ … core.c#L53

No need to guess, look at /sys/module/ath10k_pci/parameters/ to find all of the available options and their currently applied parameters. EDIT: or try loqs' suggestion /EDIT

You posted dmesg(1) output seems to show that the hwcrypto=1 option is currently applied, hence my suggestion. I can't remember what I tried with my card though, unfortunately.

Well the Intel card works fine on my Lenovo. Perhaps ask on the official support channels for a list of "approved" hardware.

My suggestion was to disable power saving. There may be a module option for that.

Yes i did disable power saving, what didn't help.
I tired to disable hw crypto with
sudo modprobe ath10k_core cryptmode=1
but that gives you errors in dmesg and not working wifi.
