The firmware hung, which is unfortunately somewhat normal, and then driver forced restart: [313384.521735] ath10k_pci 0000:00:00.0: Cannot communicate with firmware, previous wmi cmds: 36904:78270981 36954:78270754 36904:78270743 36954:78270721, jiffies: 78271552, attempting to fake crash and restart firmware, dev-flags: 0x42 [313384.543466] ath10k_pci 0000:00:00.0: failed to send wmi nop: -143 [313384.550012] ath10k_pci 0000:00:00.0: could not request stats (type -268435456 ret -143 specifier 1)
Did system recover automatically after this, or did you have to reboot it?
System recover automatically in few minutes
I have the same problem, with CT firmware sometime WIFI freezes and need to restart router to get it working again. Using non CT firmware it doesn't occurs and I get faster speeds.
This happens with 2.4GHz, on a TP-Link Archer C7 v2 with OpenWRT 21.02, using ath10k-firmware-qca988x-ct and kmod-ath10k-ct.
There as lot of topics in openwrt about it even with others OpenWRT versions, but none solution. See https://forum.openwrt.org/t/archer-c7-2-4-ghz-wireless-dies-in-24-48-hours/.
there is a workaround that works for me as well, when running the command below the problem still occurs, but WIFI continue to work after that: $ iw dev wlan_2g scan trigger freq 2462 flush
@clebersantz seems you have a different bug, your system does not actually recover with ath10k-ct driver/firmware (sometimes?) If you can get dmesg output after a freeze (and that may require serial console), then I will see if I can notice anything interesting. Please open a new bug if you want to pursue that. And, what problem still occurs but is different when you do that scan trigger freq thing? Closing this bug...plz add answers/comments to new bug.
Please provide this info. See this link for more info on how to gather debug info: http://www.candelatech.com/ath10k-bugs.php
Description of the problem (how to configure, how to reproduce, how often it happens).
Hi,
This problem happening 2 or 3 times a week. We using MacBooks connected to the router. The firmware crashes sometimes, and every device loses the network connection until the wifi restarts.
