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

[NoelNiles]

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?

Hello NoelNiles,

Thank you for posting on Intel Community Forum.

For me to assist you properly, kindly provide the information below.

1. Have you confirmed that the laptop fully supports Linux Operating System?

2. Is the AX211 module detected by the system?

3. Is Secure Boot enabled in your BIOS/UEFI settings?

4. Are there any errors or warnings in the system logs related to Wi-Fi?

I look forward to your response.
