If anyone is interested in, the ath10k is pretty ugly per some forums I searched. The first one is probably fixed in the newer kernel (https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/drivers/net/wireless/ath/ath10k?id=168f75f11fe68455e0d058a818ebccfc329d8685)

I haven’t searched for the second one yet.
And the USB one is out of my interest.

This patch is present in mainline kernel since 2018-10-10, since 4.4.164, and should be present in Omnia kernel. Do you still have these crashes? I do, unfortunately.

#MeToo

I updated my omnia box to the turris-os-4.0.3 and the 5GHz WiFi is still not stable and thus unusable. Now, I have default (not -ct) configuration.

By the way, it seems to me that these failures occur only when I use my Mac machine. I haven’t observed that with my DELL laptop.

6

i had this issue too on my omnia device and v4.0.3.

i replaced:

ath10k-firmware-qca988x - 2018-05-12-952afa49-1.12
kmod-ath10k - 4.14.158+2017-11-01-10-0a66bb0316b4402bf65555c64ceed313.2

with

ath10k-firmware-qca988x-ct-htt - 2018-05-12-952afa49-1.20
kmod-ath10k-ct - 4.14.158+2018-03-16-30827f7d-3-0a66bb0316b4402bf65555c64ceed313.2

and for me it is more stable, no firmware crashes, but i did not do a longtime test.

i also tried the latest official firmware from december 2019, but it was also unstable. the ct-firmware (htt-version) seems to run quite fine for me.

Well thanks.
How does one mortal like me replace the modules/drivers?
And where do I download the files?

8

i did it with ssh, but it should work also with luci web interface and the package management, but i would not do it, if you are not familiar with basic linux administration, as you are hacking your device :):

opkg update
opkg remove ath10k-firmware-qca988x
opkg remove kmod-ath10k
opkg install ath10k-firmware-qca988x-ct-htt

SSH’s fine. I will take a schnapps backup snapshot.

So far so good, 4 days up and running.

11

The same for me. I tested CT firmware a year ago and it was not stable like the current one - it crashed about once for a couple days. Now, it seems to be more mature and could be considered as a solid solution. Hurray!!!

The default firmware is unusable.

12

Nice to hear! There is also a none htt version of the ct firmware, which was often discussed here, but i never tried it, maybe this one is not as stable as the htt version. Like described here and here the htt version is handling management frames differently. candela tech is also offering other firmware options / features and newer ones, but as it is running quite well for my setup, i’m not toching anything right now. :slight_smile:

13

Just want to weigh in and say thank you for posting this.

I’ve been running Turris OS 4.x for quite some time on my Omnia and I’ve had so much issues with WiFi. A lot of times, even with good signal when waking up my phone or ipad from sleep it’s been unable to connect and I had to toggle the WiFi for internet to work.

Since installing the -ct-htt according to loom’s instruction 5 days ago I have yet to see that specific issue. Hopefully it stays away, I was getting mad by this issue because there was rarely anything in logs or dmesg indicating a issue, and it always worked fine after toggling WiFi on the device (so might very well be a device specific incompatibility issue but I have not had it anywhere else than on my home network).

Not sure if this is the right place to suggest, but maybe the Turris team should consider using the Candela firmware/driver (again? I have some memory of seeing it being the default a lot time ago on 3.x?). I bet there are a lot of for-and-against, but I will stick with -ct for now at least.

I got upgraded to Turris5 now and lost my 5 Ghz.

I had to log in and fiddle a bit, I believe this was what solved it

opkg remove kmod-ath10k
opkg install kmod-ath10k-ct

then reboot and I had my 5 Ghz back.

15

I am having issue with this driver as well, but not at boot as the OP. more like @jjcale

Lots of those messages, and then no more wifi

 ath10k_pci 0000:02:00.0: SWBA overrun on vdev 0, skipped old beacon

I figured this happens more often as I play stadia with my macbook, which looks like coherent with what @vookimedlo1 is reporting.

I got that a few time over the last few month, and usually rebooted and retrieve my wifi, but I am now trying the ct firmware and will report if I’ve got more stabilisation.

@ge-man, you missed the actual installation of the firmware, which looks like the correct fix.
firmware is the small software which is uploaded inside the wifi chip, and manages the very low level logic of the wifi chip. kmod-ath10k-ct is only the driver, which is for such card barely a message passer (of course I simplify)

So for the TLDR’s guys like me, who go straight to the end, the solution is really

opkg update
opkg remove ath10k-firmware-qca988x
opkg remove kmod-ath10k
opkg install ath10k-firmware-qca988x-ct-htt

So next day stadia session. 2 firmware crashes.
At least the driver seems to detect it and restart the firmware.

However the wifi session is dropped, and the macbook will not realise it until I force a disconnect/reconnect cycle.

Here are FWIW the relevant dmesg lines, with home network mac addresses redacted though.

Can confirm that.

This is happening completely random. Strange thing is that nothing actually helps to sort this out. I have tested module: ath10k-firmware-qca988x-ct-htt and it seems to be very unstable I mean kernel is able to restart it after a crash but it is happening like ~20-30 times a day and log has records about dnsmasq-dhcp address disassociation and renew, also it takes some time to start 5GHz and connect client back so for a while you are on cell data. So really unpleasant.
However when module is down everything else seems to be fine e.g. 2,4GHz wifi-OK but only for already connected clients (means you can’t connect with another client until router is restarted), wireguard server-OK, DNS server-OK, SSH server-OK.
The only solution for crashed module is to reboot router. Other commands like service networking restart and so do nothing.

Hi,

I doubt it’s related to stadia. In my home wifi there are no clients using stadia, but still I experience a similar issue (a lot of microsoft teams traffic lately)

Do you see any progress on this issue? My Wifi also suffers from it on a Turrix MOX with BG Module and 2 Qualcomm Wifi Cards running on 2.4 GHz and 5 GHz. Today we had 83 DBG Buffer drops in 10 hours.

So a few days ago I realized that I have guest wifi set up on 5Ghz wireless interface along with my ‘common’ SSID. After turning it off (means that I moved guest wifi to 2,4Ghz) issue seems to be gone. No problems at all.
But I will still watch logs for possible troubles with ath10k-firmware*.
