iPhone FaceTime Crashing/Disconnecting WiFi

Hello,
I’d like to report a serious bug/wifi problem. I keep getting disconnected from the wifi on my iPhone during FaceTime calls. It was quite suspicious for a while and I was finally able to confirm this is something the Turris Omnia Wifi card is responsible for.

I’d appreciate any ideas on how to perform more detailed diagnostics.

See the following kernel log:

This is likely a related thread: Wireless instability on ath10k radios after upgrade to 21.02.1 - #25 by khimaros - Installing and Using OpenWrt - OpenWrt Forum

I would recommend to disable 802.11w, but maybe, this is related to another setting…

Thanks for the suggestion. I disabled it and I’ll keep testing it.

There is still this mysterious message:

[16948900.067922] ath10k_pci 0000:02:00.0: pdev param 0 not supported by firmware

Any ideas on how to get rid of it?
