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 :(

  • These problems can finally be solved now. Wifi works if you update to latest linux kernel and firmware. Bluetooth: https://www.reddit.com/r/NixOS/comments/17z0p46/howto_drive_bluetooth_on_12th_gen_intel_ax101/ Not tested on Ubuntu, though :( – ken super Nov 20 '23 at 03:38

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:

  • A this is both an unsupported kernel and a kernel that is still under development this is not an answer. – David Apr 04 '23 at 14:47
  • Thank you for you comment! by the official answer from intel is https://community.intel.com/t5/Wireless/AX101-Ubuntu-22-04-or-22-10-driver/m-p/1473073/highlight/true#M46650 - I need to look for help on kernel side, and it doesn't matter that on specs AX101 has Linux support. – Eugene St Apr 04 '23 at 14:57
  • hey @zhu-hai, could you please help me - how to apply your patch? – Eugene St May 08 '23 at 10:21

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.

  • There is actually a cleaner fix to this I posted in a separate but related thread: https://askubuntu.com/a/1492845/978235 – ryanovas Nov 16 '23 at 06:58

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.

  • I agree entirely and I suggest that you report a bug: https://help.ubuntu.com/community/ReportingBugs – chili555 Mar 18 '23 at 13:39
  • thank you @thewade and @chili555! Does it mean that next year I will need to use ethernet?(( I couldn't find how to request new driver support in ubuntu-help, there are only about bugs.(( PS. is it possible to start PC without monitor nowadays? or I need dummy hmdi? – Eugene St Mar 18 '23 at 14:12
  • I think it is a bug not a lack of support. Looking into the iwlwifi driver I see references to the AX101.

    However this commit removed the device ID from its PCI list so I have no idea how it could possibly map the device to the driver: https://github.com/torvalds/linux/commit/3f910a25839b13436bf0a22186f1698b23eafb91

    You can try reporting the bug to Ubuntu, or directly against the kernel at https://bugzilla.kernel.org/

    If it is a simple as adding the device ID it might be quick to fix.

  • There are any number of supported out of the box USB wireless devices; please check here: https://github.com/morrownr/USB-WiFi – chili555 Mar 18 '23 at 14:24
  • thank you all! lost in tabs. and duplicated some info - sorry about. – Eugene St Mar 18 '23 at 14:35

    found another opened issue on intel community, looks pretty fresh. I will try to follow it, give them chance ) fingers crossed. – Eugene St Mar 18 '23 at 14:46

    I would add this relevent message to your Intel community post: "No config found for PCI dev 54f0/0244, rev=0x370, rfid=0x10c000" – chili555 Mar 18 '23 at 15:19

    Thanks @chili555! Great idea! I will do! Also will leave the reference to this topic. – Eugene St Mar 18 '23 at 17:43
