Would you be in the position for testing this with a current bullseye
installer?
There have been major improvements regarding firmware installation
shortly before the release of Bullseye.
You will need to use one of the unofficial images with firmware included
for such test:

Thanks

Hi all,

Would you be in the position to test this with a Debian Bullseye installer, from
https://cdimage.debian.org/cdimage/unofficial/non-free/cd-including-firmware/11.2.0+nonfree/ ?
(unofficial, due to non-free firmware)

Hi,

I am not that skilled in troubleshooting Linux/debian, but auto detection of AC9560 is still not working(correctly). I tried, sid, testing, bullseye and buster DVD installation iso's containing non-free firmware and they will all ask for

iwlwifi-9000-pu-jf-b0-30, 31, 32, 33, 34, 35, 36, 37, 38 

According to the Intel website "34" should be the correct firmware for AC9560 and should be supported from kernel 4,4 and up.
