Hello all,
I recently bought a brand new Dell Precision 7540 laptop. Before buying
I checked the specifications from the RedHat hardware list and they said
that it was "fully RedHat 8 Certified" and listed all the hardware that
was "certified" to work with that laptop.
https://access.redhat.com/ecosystem/hardware/3979771
I have had good results the last few years with Dell and CentOS, all the
equipment has worked fine.
However, this time, I got the laptop, installed CentOS 8, and the
built-in ethernet port works fine but the Intel AX200 Wifi is not
recognized and doesn't show up, so I can't use WiFi, but everything else
seems to be working fine.
I verified that it *does* work under Windows 10, so the hardware is
there and works fine, it just is not recognized and configured under
CentOS 8.
I called Dell Tech Support and they said "since you didn't buy RedHat 8
from us then we can't help you".
Is this just a temporary problem that an update will soon solve or is
this something that needs to be brought to the attention of RedHat?
Should I file a bug report with bugzilla.redhat.com or is there
something I'm not doing or need to do correctly to get it to work?
Or is there some package I'm missing that will enable it?
I was a bit flabergasted because I've gone for so many years without
having to do anything special, it all "Just Works (TM)" on my previous
computers.
For technical details, here is what I get when I run "lspci -nn":

I believe the Intel AX200 Wifi card is the device 8086:2723 (rev1a) entry.
Is there something I can do to enable it or is this a bug I need to file
with RedHat?
