That is also not good but something I can help with working on. > Before digging in it more deeply: > _ can anyone tell for sure what this card is? 9461 or 9560? It likely is a 9461. There's a bunch of exceptions to various chipsets incl. the 9560, which iwlwifi is aware off, which determine the correct version beyond PCI IDs. > _ what should I use? iwm? iwlwifi? Anything else? I would suggest to start with iwlwifi in this case. Could you please share the full iwlwifi parts from a bootverbose, as this is peculiar case I haven't had much feedback on in the last year. Also to help with your problems mentioned above. > _ is this expected to work on 13.1?

You should go to stable/13 (or main). 13.1-R will not make you happy and/or I'll likely not be able to help much on anymore. > I know a lot of work has been going on and I've seen many info through the > mailing lists and on the wiki.
