description |
I'm using the stock Dell Ubuntu 22.04 image on my XPS 13 Plus (9320). Recently I received some kernel updates, the 5.19 kernel used in 22.10 and a 6.0 oem kernel. Both updates break wifi. It seems to only do so on newer 5.7 GHz access points.
1. Boot latest 6.0 oem kernel
2. Browse the web, usually takes between 1 and 5 minutes.
3. Networking will cut out.
Disabling networking and starting again will fix it until it happens again in a few minutes. This will repeat indefinitely, essentially making wireless useless.
The attached dmesg log reliably shows up when it fails, showing iwlwifi failing and a (network?) hardware reset request.
It witnessed this happen months ago on 22.10, which led me to using the Dell stock 22.04 image. But it seems even the newer OEM kernel is affected.
Let me know if this bug report would be better to go to Dell as a support request instead. |

A workaround is to select the older 5.15 kernel in grub. I find on this laptop, one must hit escape precisely 1 second after seeing the Dell logo on boot. Alternatively one could edit /etc/grub/default and set a longer timeout.

[SRU Justification]
[Impact]
backport-iwlwifi-dkms/kinetic is being built into hwe-5.19 kernel, and -73 firmware are supported bug missing. On one user reported issue, this fixes WiFi stability on 5G band.
[Fix]
New upstreamed firmware revision fixes this issue.
[Test Case]
1. Boot hwe-5.19 kernel
2. iwlwifi-so-a0-gf-a0-73.ucode firmware should be loaded
3. Browse the web, usually takes between 1 and 5 minutes
4. Networking will cut out
[Where problems could occur]
This affects only users need both backport-iwlwifi-dkms and hwe-5.19 kernel on WiFi stability.
[Other Info]
While Kinetic and above have them all, only Jammy is nominated.
