Research direction
Start by reproducing the AR9271 failure on a Raspberry Pi 4 with the reported firmware and aarch64 kernel, comparing it with version 1.20220308. Collect kernel and wireless logs while activating wlan0; done means identifying and fixing the regression so the TL-WN722N interface becomes usable on the newer kernel.
Written by the indexing model from the issue text.
Description
Describe the bug
The Atheros driver is not working properly with the last kernel. Specifically with AR9271 chipset of the TL-WN722N.
The wlan0 is visible but cannot be active.
Problem is solved when I downgraded to 1.20220308.
I'm using raspberry 4 with 64bit kernel.
Steps to reproduce the behaviour
Connect the usb wifi and simply don't work.
