Intel AX211 Wi-Fi Not Working on Ubuntu 22.04 FIPS Kernel

Support and Help

I’m running Ubuntu 22.04.5 LTS with the FIPS kernel (5.15.0-141-fips) on a Dell Precision 5490, which uses the Intel AX211 wireless card (8086:272b).

Wi-Fi works normally when I boot into the standard (non-FIPS) kernel, but under the FIPS kernel, no wireless interfaces appear — iwlwifi isn’t loaded, and iwconfig shows only the loopback and USB tethered interface.

Is the FIPS kernel incompatible with the iwlwifi driver or the required firmware for this card? Are there steps I can take to make it work, such as installing signed modules or using alternate drivers?

Has anyone gotten Intel AX211 to work under a FIPS-compliant Ubuntu kernel?

Here is the wireless-info log. Ubuntu Pastebin

Well, turns out the AX211 driver only works in kernels 6.14+. So it looks like this card will have to wait for a newer FIPS certified kernel. I don’t think drivers can be backported into a FIPS kernel.
