1855825.
I also noticed that although WiFi is up with 7906 + 5.3 kernel, the
authentication will never be completed on 9260, but I think there should

So this issue happens on 9260 platforms with OEM DKMS modules that are
not compatible with -46 fw. Luckily(?) enough, we have another

Emergency work-around steps:
1. remove the problematic firmware manually:
$ sudo mv /lib/firmware/iwlwifi-9260-th-b0-jf-b0-46.ucode $HOME
2. reload the iwlwifi:
$ sudo modprobe -r iwlwifi; sudo modprobe -r iwlwifi
