Random Wi-Fi Adapter Loss on Fedora 42 (Intel Alder Lake-P CNVi)

gabriel-z · May 10, 2025, 7:39am

I’m experiencing a frustrating issue with Wi-Fi on a fresh install of Fedora Silverblue 42. My Wi-Fi adapter (Intel Corporation Alder Lake-P PCH CNVi WiFi, rev 01) randomly disappears. Sometimes it comes back after a reboot, but often it doesn’t, even after multiple times.

When the issue occurs, the Wi-Fi simply isn’t available anymore. I’ve tried uninstalling any third-party drivers I might have inadvertently installed, but the problem still persists.

I’ve looked at dmesg and see the following repeating errors around the time the Wi-Fi goes down:

There are (too) often problems with WiFi with Linux updates. I find it important to have a Linux compatible USB WiFi adapter to use while waiting for a fix.

Your first step should be to ensure that you have fully updated Fedora and vendor EUFI/BIOS firmware so you aren’t chasing a solved problem. If that doesn’t solve the issue, you can try different power management settings and enabling/disabling WiFi at at boot time in UEFI/BIOS (systems often enable WiFi at boot to support netbooting for mass updates in cubicle farms, etc.)

If you are still having issues, we will need to know if you are booting another OS and syste details, e.g., inxi -Fzxx output.

A recent report for Arch Linux for an Alder Lake-P PCH CNVi WiFi (rev 01) that switching to iwd from iwlwifi whwn $ nmcli radio showed wifi-hw as “missing”.

gabriel-z · May 13, 2025, 5:16pm

Command $ nmcli radio didn’t show WIFI-HW as missing for me.

gnwiii · May 16, 2025, 1:22pm

Are you still having this issue with recent firmware and kernel updates?

gabriel-z · May 17, 2025, 6:22am

Yes, I am still experiencing the issue despite the recent firmware and kernel updates.

gnwiii · May 17, 2025, 6:16pm

Are you still seeing:

The LHDB probes for model pci:8086-51f0 have mostly “not working” results, but also some user comments pointing to firmware that does work.

Your issue is unlikely to be specific to Fedora. It is not unusual for upstream vendors to make mistakes when updating firmware that don’t work for the latest kernels – new hardware gets the most attention and developers don’t usually have access to the full range of older hardware when testing. Some vendors have their own firmware versions, so worth checking your vendor’s support site.
