After reading available pages with keywords similar to those included in topic I decided to ask a question since I really don't know what to do.
Few days ago I bought new DELL XPS 15 9500 (i9 version) with network adapter Killer AX500s DBS. Wifi and bluetooth isn't visible at all on Ubuntu 20.04[.1] and default kernel 5.4.x. I tried to install the drivers, changed kernels (even to 5.9) but no luck - in last case bluetooth icon appeared but wasn't working properly (even turning it on was failing, if managed to turn it on - couldn't connect to my mouse). I found out that mentioned network adapter is currently not supported:
- certification notes (XPS 13 wth the same module)
- tracking and additional articles
My question is: Does anyone know if it will be supported soon or ever (I have to decide if I should return new computer - time is limited here)? If no - where should I ask for it? I'm really confused about it and don't know if it's worth to wait.
I found out there is some driver - Does someone tried to install it manually (how? It's last thing I didn't try) and did it work?

I just found out there is support for AX500s DBS in the "linux-firmware" package ver 1.187.7, which is currently in ubuntu proposed:
I can confirm I'm now running Ubuntu 20.04.1 on XPS 13 9310 (late 2020), connected via the AX500s DBS Wifi.
To get the wifi card recognised, I had to:
# sudo apt install linux-oem-20.04-edge # installs kernel version 5.10.0-1008-oem
# sudo apt install linux-firmware=1.187.7 # from ubuntu proposed, which I temporarily enabledThe issue related to Killer ax500 was resolved by updating the kernel to the version 5.10.3. I am using ubuntu 20.04 and the wifi and Bluetooth are working perfectly. All the best
I have wifi functional on my XPS 15 9500 i9 (side note: I am running 20.10 not 20.04, so results may very).
I was first looking into this article that claimed to solve the issue: , however I found it odd that the linked LKML page said this was added in kernel v5.10-rc2 while v5.10.4 is out.
So first, I updated my kernel to 5.10.4:
Then, as referenced on LKML , I cloned and copied the firmware files to the appropriate directory:
sudo mkdir -p /lib/firmware/ath11k/QCA6390/hw2.0/
sudo cp QCA6390/hw2.0/WLAN.HST.1.0.1-01740-QCAHSTSWPLZ_V2_TO_X86-1/*.bin /lib/firmware/ath11k/QCA6390/hw2.0/
sudo cp QCA6390/hw2.0/WLAN.HST.1.0.1-01740-QCAHSTSWPLZ_V2_TO_X86-1/bdwlan.e04 /lib/firmware/ath11k/QCA6390/hw2.0/board.binAfter that I restarted my computer and had the ability to connect to wifi networks.
3I'm following this issue for more than 7 months now since I got my Dell XPS 9500, with a Killer Wifi 6 AX500-DBS card. I was able to use it by upgrading to Ubuntu 20.04.2 running on Linux kernel 5.11.
I received a new XPS 13 9310 and Ubuntu 20.04 did not work, however Ubuntu 21.10 works out of the box.
New XPS 15 with fresh 21.04 install two weeks ago 05/05/2021.
I'm having issues, twice in the past 2 weeks, on my new XPS 15 9500 and 21.04 with wifi working fine initially then not available. lspci shows the card.
After trying numerous troubleshooting options found online in desperation I usb boot back to 20.10. wifi isn't available there either.
Reboot to installed 21.04 and mysteriously wifi is back on.

Finally, i found a guide that resolve the AX500 issue for me, following step by step this guide
Some suggestions
- don't install the new kernel 5.9 before. During the procedure you will install also the kernel 5.9rc5 (yes, is a release candidate and maybe will have some issues, i will test it during the next days);
- before to start with the guide, install pahole (minimum version required is 1.16). You can find the link here for version 1.17.1
- when you will finish to set the configuartion file in the guide, save it as .config.
I hope that this will work also for you.
I bought a standard (not developer version) XPS 13 9310. The AX500 wifi chip was not recognized by the normal 20.04 or 20.10 Ubuntu installations.
I tried a nightly version of the upcoming 21.04. The installer does not have the driver for the Wifi, but after installation the AX500 is recognized and working fine. I was connected to Ethernet during the installation, I dont know if the driver is in the standard installer or was pulled in as an update during installation. When installing I would recomend being connected to the network somehow just to make sure the AX500 driver is available afterwards.
Here is the link to the Ubuntu 21.04 daily builds:
0I had the same problem with the machine on ubuntu 20.10. I upgraded to 21.04 and now the WiFi is working
0I can confirm Dell XPS 15 9500 i9 Ubuntu 20.04 after updating the kernel to version 14 Wi-Fi is back working properly
I have the same issues with the same laptop (XPS 15 9500 I9 version). I have noticed that the support for Killer wifi ax500 will be available with the release of the new kernel 5.9.
The stable version will be released on 11th of October or next week.
