Description Richard Kimberly Heck 2025-10-08 00:58:54 UTC
I have a System 76 Pangolin 15 laptop. The wireless card shows up in lspci as:

01:00.0 Network controller [0280]: MEDIATEK Corp. MT7922 802.11ax PCI Express Wireless Network Adapter [14c3:7922]
        Subsystem: AzureWave Device [1a3b:5141]
        Kernel driver in use: mt7921e
        Kernel modules: mt7921e

All was well until I updated the system and installed mt7xxx-firmware-20250917-2.fc42. After the update, the wireless device was not available. It still showed up in lspci, but neither nmcli nor rfkill showed the device. Downgrading to mt7xxx-firmware-20250311-1 solves the problem.

Reproducible: Always

PS I reported this on the user list as well. It was suggested I try "pcie_aspm.policy=powersave" or "pcie_aspm.policy=performance". Neither helped.
