I need your help with setup wifi on my mini-PC. CPU Intel N100, that includes wifi. default winOs had seen wifi and worked well. I've already tried ubuntu 22.04 and 22.10, tried to install backport-iwlwifi-dkms, copied iwlwifi files from kernel linux github to /lib/firmware, upgraded kernel... OS doesn't see wifi at all and bluetooth is not switching ON.

So everything what i found already - didn't help me.

# dmesg | grep iwlwifi
[    2.573402] iwlwifi 0000:00:14.3: enabling device (0000 -> 0002)

[UPDATE]

found this - sounds promising. Also found few requests on intel community about support Linux, as it's promised on specs page. will update mine findings here

[UPDATE 2023/04/04] intel community couldn't provide the support and forwarded to kernel.org :(

It's a bug of ax101 driver, and unfortunately still not fixed in the latest kernel 6.3-rc5.

I can connect to WIFI5 AP after applying following patch . linux 6.1.20

But it would still failed to connect to WIFI 6 AP due to firmware error, so you must disable 802.11ax when loading driver :

modprobe iwlwifi disable_11ax=true

or write options iwlwifi disable_11ax=true to /etc/modprobe.d/iwlwifi.conf and update-initramfs -k all -u to make it persistent.

Another bad news is bluetooth still not works due to lack of firmware ibt-0040-1050.sfi:

Zhu hai patch looks correct. It is similar to the Arch patch which definitely works on 6.2.x kernels. https://aur.archlinux.org/packages/iwlwifi-ax101-dkms

I have tested a workaround for the blutooth issue. Rename the files ...

/usr/lib/firmware/intel/ibt-1040-4150.ddc.xz
/usr/lib/firmware/intel/ibt-1040-4150.sfi.xz

to

/usr/lib/firmware/intel/ibt-1040-1050.ddc.xz
/usr/lib/firmware/intel/ibt-1040-1050.sfi.xz

The 1040-4150 fw is for an earlier version of the AX201 bluetooth usb.

I've listened to BT audio and played w/ several BT devices this way. No promises.

The device appeared in your lspci output: Subsystem: Intel Corporation Device [8086:0244]

That is the Intel AX101, which was only released in Q3'22: https://www.intel.ca/content/www/ca/en/products/sku/203014/intel-wifi-6-ax101/specifications.html

It is possible that your device does not yet have Linux support. Support might come in a future kernel.
