I have hardware.firmware = [ pkgs.linux-firmware ]; in my system configuration. However, I checked /run/current-system/firmware, and didn’t find firmware related to MT7925. As it supposed to be here accroding to Linux firmware git repository . [屏幕截图_20251017_010556]

Does the directory /run/current-system/firmware/mediatek/mt7925/ not exist for you? It exists for me on nixos 25.05 and has files like BT_RAM_CODE_MT7925_1_1_hdr.bin.zst (matching what’s in mediatek/mt7925 · main · kernel-firmware / Linux Firmware · GitLab ).

Missing MediaTek firmware!

But I wonder if it is correctly loaded.

Do I have to add these parameters?
