Intel Corporation Comet Lake PCH CNVi WiFi

For Developers

Hi,

I'm using an OpenWRT snapshot with Docker support on a Thinkcentre M90q. Everything is working well with several Docker containers running Debian. The M90q has an Intel Corporation Comet Lake PCH CNVi WiFi which I'd like to use.

lspci reports the device as:

Intel Corporation Comet Lake PCH CNVi WiFi [8086:06f0].

I've installed the iwlwifi kernal module but syslog, on boot, complaines about missing firmware:

iwlwifi 0000:00:14.3: minimum version required: iwlwifi-QuZ-a0-jf-b0-39
iwlwifi 0000:00:14.3: maximum version supported: iwlwifi-QuZ-a0-jf-b0-59

The WiFi works fine on Ubuntu 20.04. My question is how would I go about creating an
OpenWRT firmware module for this device that's, presumably, based on the code being used by Ubuntu?

Thanks in advance.

Cheers, Steve

You can find the firmware here: https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git . You could copy it to the appropriate subdirectory which I think is /lib/firmware .

I downloaded linux-firmware-20210818.tar.gz from thle link you provided. Unzipped it and copied iwlwifi-QuZ-a0-jf-b0-59.ucode to the OpenWRT /lib/firmware folder as you suggested.

Rebooted and the wireless scan works.

You're a fine fellow, thankyou so much.
