Hello,

kernel Linux 6.1 Wifi is not recognized at all. Is the PCIe device ID
missing in the rtw89 driver?

That driver will not be in the kernel until kernel 6.2, which is predicted to be
released on Feb. 19, 2023.
In the meantime, clone the rtw89 repository at
https://github.com/lwfinger/rtw89.git, and follow the instructions in README.md
in the cloned repo. Pat particular attention to the last paragraph if you are
running Ubuntu. For some reason, they have not included the firmware for this
device even though it has been in the official linux-firmware repo since October.
