Please try disable Windows Fast Startup:
This is the most common cause of this error in dual-boot systems.
Windows leaves the Wi-Fi card in an active low-power state that Linux
cannot initialize. Boot into Windows, open Control Panel > Power Options
> Choose what the power buttons do, click "Change settings that are
currently unavailable," uncheck Turn on fast startup, and shut down
completely.
** Description changed:
Steps to reproduce:
Boot Dell Latitude 5450 (Meteor Lake, Intel Core Ultra) with Ubuntu 26.04,
kernel 7.0.0-15-generic
Run modinfo iwlwifi | grep 7e40
Expected: Device ID present, iwlwifi binds to 00:14.3
- Actual: No output. iwlwifi loads but never binds. No dmesg output from
iwlwifi at all. lspci -nnk shows Kernel modules: iwlwifi but no Kernel driver
in use. /sys/bus/pci/devices/0000:00:14.3/driver does not exist.
+ Actual: No output. iwlwifi loads but never binds. lspci -nnk shows Kernel
modules: iwlwifi but no Kernel driver in use.
/sys/bus/pci/devices/0000:00:14.3/driver does not exist.
Device: 00:14.3 Network controller [0280]: Intel Corporation Meteor Lake PCH
CNVi WiFi [8086:7e40] (rev 20), Subsystem: [8086:4090]
Note: This is distinct from LP #2037390 where iwlwifi was probing the device
but failing on missing firmware. Here the PCI ID 7e40 is entirely absent from
the module — the device is never attempted.
