Intel Alder Lake-N100 wifi and bluetooth issues

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

[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 :(

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

/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.

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.

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.

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

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?

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

found another [opened issue](https://community.intel.com/t5/Wireless/AX101-Linux-driver/m-p/1465559#M46101) on intel community, looks pretty fresh. I will try to follow it, give them chance ) fingers crossed.

I would add this relevent message to your Intel community post: "No config found for PCI dev 54f0/0244, rev=0x370, rfid=0x10c000"

Thanks @chili555! Great idea! I will do! Also will leave the reference to this topic.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
