Starting from kernel 6.13, the wifi adapter is no longer recognised on kernel 6.13. Judging from the logs, it seems that the firmware is no longer being recognised.

Some logs that might be useful:

Kernel config:

I assume the Asahi Linux folks also have the issue.

Let me know if some other information is needed

Thanks
