[CentOS] CentOS 8 and DELL 7540 Intel AX200 WIFI

2020-01-19 Thread David Summers 


I just wanted to follow up to my post from October 2019.


I just installed CentOS 8.1 and my WIFI card is now detected and works 
properly!



So I'm a happy camper again, I guess I just had hardware that was too 
new and CentOS 8.0 didn't have the driver for my WIFI card but CentOS 
8.1 *DOES* have it.



Good thing, Both RedHat and DELL says it is "completely supported".


I was seriously thinking about sending the hardware back to Dell to 
reorder a configuration that worked, but now I don't have to, there is 
now driver support for the Intel AX200 WIFI card.



I just had to unexpectedly wait a few months.


   - Thanks

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

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)

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.

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

[CentOS] CentOS 8 and DELL 7540 Intel AX200 WIFI

2019-10-25 Thread David Summers 


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.
