    Hi anticapitalista,

    You were absolutely right! I just booted into the 5.10 ‘legacy’ kernel on battery power, and the Wi-Fi works flawlessly without any delays or hardware lockups.

    There is definitely a power management/ACPI regression in the 6.6 kernel series specifically for this Atheros card when running on battery.

    I will set the 5.10 kernel as my default and stick with it. Thank you so much for the incredibly fast help and for an amazing distro!
