I have NUC 7PJYH with Intel wireless AC-9462 card. The problem is that systems randomly freezes when using WiFi. There are no freezes when wifi is disabled. I tried to use different kernels, but still the same behaviour.
dmesg when I was on kernel 4.16.12 and I found that the kernel is asking for
iwlwifi-9000-pu-b0-jf-b0-36 firmware files. I tried to find these files on wireless.wiki.kernel.org. I went through all repositories they maintain and I found only versions 34 and 38 of this firmware.
Where can I find the correct firmware for kernel 4.16? These files are not even in the official
linux-firmware package tree.
wifi related dmesg output:
