Anyone with some Dell laptop XPS 13 9370 (2018) experience here?
Especially with that "Killer 1435 (802.11ac 2x2 und Bluetooth)" device?
Supported by the stock kernel (EL7)?
I had reasonably unreliable performance with that particular
chip(sometimes wireless wouldn't wake up from sleep and I'd have to
reboot), and ended up replacing it with an intel 8265 chip. It takes
about 10 minutes to swap, and got me much better performance on my 9370.
Link below is the one I picked up, but you may be able to find it for
cheaper. Dell tells me that swapping it doesn't void the warranty, so
I'm good with it.

Thank you for taking the time. A valuable information! The 9365 variant seems
to be shipped with a Intel8265 card. I will get in contact with DELL and try to
request it for the 9370 model ...

I have an xps 13 9360 and had problems with the killer wireless. I got
virtually 0 support from Dell on this issue. Some people who upgraded
their warranty to Dell Pro Support were able to get dell to send them a
new ethernet card, but some upgraded their support and still got no help.
I am running Ubuntu 18.04 on mine. A while back, I don't know the exact
date, there was a substanial bugfix in the mainline kernel which
appeared in the Ubuntu kernel roughly in the May/June 2018 timeframe
which improved support for the killer chip. You might check to see if
this bugfix got backported to redhat/centos. Also some people have
tweaked some parameters in the driver and improved the performance of
their killer ethernets.
Before you order a card, I suggest you verify that your laptop actually
has one. (I believe if you download the manuals for your xps, it will
include instructions for replacing the card if it is replacable). My
understanding was that as of the 2018 models, most, if not all of these
laptops switched from using cards to soldering the chips directly on the
motherboard.
I did replace my ethernet card with an Intel 8265 card (my xps is a 2017
model). For me the 8265 works well with some wifi hubs, but has packet
loss problems with others, particularly some older hubs that I have. I
did verify that the killer card performed well under windows 10 with the
same hubs which did not work well under Linux.
