Hi, thanks for your answer! In fact, XPS 15 9500 *have* a QCA6390, but only the i9 version (which I have).
So I've made progress: it appears I had both software and hardware problems since it also stopped working in Windows. Sometimes the card is gone (not appearing in the devices manager), and when I reboot it's back (or not). That introduced a big confusion variable when I tried different solutions yesterday, because indeed the card was just disconnected (or appeared so to the system). So, right now it's back online, and I've got it working now (with linux- oem-20.04b and linux-firmware=1.187.9 from focal)! Or at least, partially. *Like other people in this thread*, I get stack traces and errors in the kernel log (attached). Connection to a hotspot can't be done or lasts for a second or so, and it makes the system unstable. Is there a known solution (I can't find one here), should I open a new bug report for this, or is there already one? ** Attachment added: "kernel.log" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1879633/+attachment/5475148/+files/kernel.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1879633 Title: Killer 500s (QCA6390) WLAN/BT [17cb:1101] unavailable To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1879633/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
