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?

says that the AX200 is supported with Linux Kernel 5.1+, and the firmware linked on that page.

Device ID pair [8086:2723] is not in the current CentOS kernel 4.18.0-80.11.2.el8_0. However, it is found in the CentOS Stream kernel 4.18.0-144.el8. So, you may want to give it a try.

I would file the bug even if you get it working. Otherwise, as it stands RH is saying get this machine, it works, and it doesn't.
There do seem to be workarounds, such as a newer kernel or the stream kernel, and I don't know how close CentOS-8 is to RH-8, but as it is, if was running CentOS-8 I'd expect it to work out of the box and it doesn't.
So, for the sake of the next person with $1200 to spend on a laptop, tell them. Maybe someone will save the money and spend it on something that actually does work out of the box.
(overly fed up with manufactures putting out incorrect compatibility lists, and will definitely feel silly if someone says, naw, worked out of the box for me with RH-8)

You probably need to install the firmware. Which is probably in a separate package that is not installed by default.
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?
