WiFi adapter not working on XPS 13 9310, Ubuntu 20.04
I recently received an XPS 13 9310 from my new employer and replaced its operating system with Ubuntu 20.04.
I haven't been able to get the WiFi working correctly - sometimes the adapter will show up and work for a bit, and sometimes it won't.
Ethernet seems to work fine.
All the threads I've found by googling have similar issues but not quite the same and their solutions haven't worked for me - they mostly seem to be using older versions of Ubuntu and fix the problem by upgrading to a later version or the latest kernel. I've tried Ubuntu 21.04 and 18.04 and it didn't change anything.
I've also experienced an issue where the screen will randomly freeze, mouse and keyboard stop responding and I'm forced to power off and on again. I don't know if this is related.
Here are the outputs of various commands that may be helpful:

Solution 1:
This is a known issue with older kernels. I was able to fix this by installing a newer kernel with apt install linux-image-generic-hwe-20.04-edge or apt install linux-image-5.13.0-1009-oem
You can see a full list of available kernels with apt list linux-image*
Ensure that linux-firmware is up to date also, or experiment with the latest wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/iwlwifi-QuZ-a0-jf-b0-63.ucode -O /usr/lib/firmware/iwlwifi-QuZ-a0-jf-b0-63.ucode
Other things you can experiment with:
- Update the firmware on the device with
fwupdmgr refresh --force && fwupdmgr upgrade - Change
wifi.powersaveto2in /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf - Experiment with kernel cmdline options such as
pcie_aspm=off, full list available here: https://www.kernel.org/doc/html/v5.11/admin-guide/kernel-parameters.html sudo add-apt-repository ppa:canonical-hwe-team/backport-iwlwifi && sudo apt-get update && sudo apt install backport-iwlwifi-dkms
