*Edited after super helpful chat with @chili555 that I botched by trying too many things at the same time...

The WiFi adapter works in kernel 5.13.0.20-generic, but in 5.13.0-21 it's inactive and remains inactive after multiple shutdowns/ reboots. I checked that it's active in BIOS and it exists but does not work

$ rfkill list all

It is not present in networkmanager or ifconfig, Bluetooth works though which I believe is the same device. Super thankful for any ideas.

The ax500 device works in the 5.13.0-20-generic kernel with

Please edit your question to show the result of the terminal commands: `sudo modprobe ath11k_pci` and: `sudo dmesg | grep ath` and,finally: `rfkill list all` Welcome to Ask Ubuntu.

nothing for the first two, something about bluetooth for the last

Let's try to provoke a response: `sudo modprobe -r ath11k_pci && sleep 5 && sudo modprobe ath11k_pci && sudo dmesg | grep ath`

nothing but total silence

Whaa?? Please reboot and try the last sequence again. Why do I get all the stubborn cases? :-((

axtimwalde

Same result. I know, it's really weird. Happened yesterday after they rolled out a kernel update.

Argh! I made a big mistake

axtimwalde

3/10/23, 1:01 AM

Sorry, I had tried too many things at the same time when you helped m in the chat. I had disabled the UEFI wifi stack option in BIOS because I did not know what it does. This seems to disable the device... I went back and booted the -20 kernel and the device works with that kernel!

Please file a bug with `ubuntu-bug linux` with this information. Thanks.

Done https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1950515 It looks like this is a recurring regression that has been going on forever. A fix seems to exist https://bugzilla.kernel.org/show_bug.cgi?id=214455 but the regression keeps making it into distributions.

This works again with the now released kernel 5.13.0-22.

sudo apt update
sudo apt upgrade
sudo reboot

and if you never want to see this again:

sudo apt purge linux-headers-5.13.0-21 linux-headers-5.13.0-21-generic linux-image-5.13.0-21-generic linux-modules-5.13.0-21-generic linux-modules-extra-5.13.0-21-generic

Is suspend/hibernate working ok with this card?

axtimwalde

5/20/23, 9:01 PM

I would say most of the time. But this XPS 13 9310 certainly has more issues with suspend/hibernate than the 9370 that I had before. I have not investigated whether those issues are related to the WiFi card or something else. The most severe and frustrating is the computer NOT going to sleep but silently cook in the bag until the battery is out. I had a few cases of WiFi not being functional after wake but could always remedy this by software off/ on.

Thank you @axtimwalde for answer. I've decided to buy XPS 9300 because of ax1650s inside of it.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
