Re: Re:Intel AX101 WRDD/DFS issues on Debian 13 Trixie

RicoBelo · ‎10-22-2025

I have a chinese Mini-PC with an Intel N150 CPU and a soldered Intel AX101 wireless card running Linux Debian 13 (Trixie)

want to use the wireless card as an AP, which is supported by AX101 chip and driver, in 802.11ax mode on the 5GHz band.

As I live in France, I forced cfg80211 module to load WRDD for France with the kernel parameter

cfg80211.ieee80211_regdom=FR

The global registration is then correctly globally set to FR, but the wireless card is kept unconfigured with no country and no DFS information:

At least I can see many channels in the 5GHz band available for DFS. So I try a minimalistic hostapd.conf file to start an AP centered on channel 100 with 802.11ax, but it fail : hostapd enumerates all channels in the 5GHz band with "No IR" flag :

So I tried to enable DFS and force 80MHz band centering between channel 100 and 106 with a more elaborated hostapd config. Bu once again, hostapd fails to start because it fails to start DFS scan.

I was able to start hostapd in 802.11ax on the 2.4GHz band as there is no DFS gotchas on the band, but at the price of terrific bandwidth of less than 90Mbps.

I join my dmesg, config files, and iw outputs in attachements

So at this point I assume the firmware forbid me to use the card in AP mode on 5Ghz band because of DFS, I don't really understand how and why. So can you help me to fix this ?

Hello RicoBelo,

Thank you for posting on Intel Community Forum. I appreciate your effort for sharing as much information as you could. This will definitely help with the investigation moving forward.

To address the issue properly, kindly share the information below.

1. What is the make and model of your Mini-PC? If possible, kindly share the direct link to it.

2. Were you previously able to configure and use the wireless card according to your preferred settings?

3. What is the Kernel and firmware version?

I look forward to your response.

Best regards

Hello Jed, thanks for your support

1. I brought this mini-pc on a French second hand market website called "leboncoin.fr" which will obviously not your :D, but the miniPC is branded "SOAYAN N2" and I found references on Alibaba and also Amazon :

https://www.amazon.fr/SOAYAN-Lake-N150-Computer-Business-Heimkino/dp/B0DTF11ZFT

https://www.alibaba.com/product-detail/SOAYAN-2025-Factory-Direct-N2-Mini_1601390125662.html?spm=a2700.details-description.0.0.79eeM2XVM2XVqW

This is obviously a generic product sold to many distributors, and unfortunately I was not able to find the manufacturer or any support.

2. Initially I didn't used the wireless at all : I use this server to share and transcode media files with Jellyfin over Ethernet, thanks to it great CPU and IGP (the N1xx series are really great and green products !)

But as I recently added a new FireTV 4K with a weak wireless connection because my "real AP" is too far, and the mini-pc is just next to the FireTV stick, I through bridging the wireless card would be an far more elegant option than adding another AP !

The FireTV 4K is the reason why I want 802.11ax over 5Ghz : I want to archieve at least 500Mbps bandwidth with low latency

3. You can find kernel and firmware details in dmesg.txt output. For reference :

regulatory.db                  manual   /lib/firmware/regulatory.db-upstream

RicoBelo · ‎10-23-2025

Hello Jed,

1. This is a generic chinese mini-pc, branded as "SOAYAN N2 Mini PC N150". You can find it on AliBaba as well as Amazon :

https://french.alibaba.com/product-detail/SOAYAN-2025-Factory-Direct-N2-Mini-1601390125662.html

https://www.amazon.fr/SOAYAN-Lake-N150-Computer-Business-Heimkino/dp/B0DTF11ZFT

I search for an eventual official website but didn't found anything suitable to request any support from the manufacturer.

2. Not really : I usually prefers Ethernet connection when possible so wireless was disabled. The reason why I need to activate it as AP is this host is exclusively used for transcoding media content using Jellyfin, and I just added an Amazon FireTV 4K stick with a weak Wifi connection because my "real" AP is to far away, so as the Mini-PC is just next to the FireTV stick, I thought far more elegant bridging its connection as an AP than installing another "real" AP for just one device.

3. I think you already have these information on the dmesg.txt attached file. FYI:

# uname -a

So:

kernel is stock Debian 13 (kernel 6.12.48)

firmware blob is 89.4d42c933.0 so-a0-hr-b0-89.ucode

I also need to precise that I switched to upstream regulatory database instead the the stock Debian provided :

# update-alternatives --get-selections | grep regulatory
regulatory.db                  manual   /lib/firmware/regulatory.db-upstream

Hello Jed,

I downloaded ssu_3.0.0.2_tar.gz and ran it on my system. the log is in attachment.

Hello RicoBelo,

Thank you for providing the SSU report, I appreciate it. Can you please also confirm if you were able to contact the Place of Purchase already about this issue?

I hope to hear from you soon.

Hello Jed,

The short answer: no !

The long one: I contacted the manufacturer on alibaba marketplace explaining almost what I detailed here... and he sent me a ZIP file containing Windows wireless drivers

JedG_Intel · ‎10-28-2025

Hello RicoBelo,

Thanks for the added information. Could you please confirm whether the driver supplied by the manufacturer worked for you?

Best regards

Hi Jed,

As said, they only provided *Windows* drivers, while I'm running Debian 13 !

How do you expect me to use Windows drivers on a Linux system ???

Regards,

Eric

JedG_Intel · ‎10-29-2025

Hello RicoBelo,

I apologize for any confusion. I had assumed that you previously attempted to use the Windows Operating System, as the manufacturer provided you with Windows drivers. Nonetheless, I will continue investigating this matter and will reach out to you with an update as soon as possible.

Hello RicoBelo,

I am reaching out to provide you with an update. To continue troubleshooting the issue, please download the latest Kernel version 6.17 from The Linux Kernel Archives. Additionally, ensure that you are using the most recent firmware available in the Firmware git tree.

If the issue persists after implementing these recommendations, kindly inform me so that we can proceed with further troubleshooting.

Best regards

Hello Jed,

Sorry for late answer, I was off last few days and didn't have the opportunity to rebuild a kernel.

I try to do this ASAP then I'll come back to you to inform of the results.

Regards,

Eric

Hello RicoBelo,

Thank you for sharing the output after trying the latest Kernel. We'll continue to troubleshoot the issue and I'll get back to you once I have another update.

Best regards

Hello RicoBelo,

After checking with our team, the no Initiate Radiation (IR) indicates that under the current regulatory setting (DFS-UNSET), the channel cannot be actively used until the system first detects another Wi-Fi transmitter operating on that same channel. To proceed further, please try the steps below.

Channel Scan: Please perform a scan on the target channel before checking the regulatory settings with iw reg get
Verify Country Code Change: After scanning, check if the regulatory domain updates to France:

phy#0 (self-managed) country FR: DFS-UNSET

(Ensure country_code=FR is configured in hostapd.conf file)

Network Manager: Consider enabling and running NetworkManager, as it typically handles the necessary regulatory and dependency configurations required for proper AP mode operation.

If the issue persists, please let me know.

Best regards

Hi Jed,

I rebooted the computer to get everything at initial state, then requested regulatory info, which displays "00: DFS-UNSET" as usual, then started a scan with the command "iw dev wlo1 scan ap-force", and finally re-checked the regulatory domain: it switched to FR, but remained in "DFS-UNSET" state.

I can't figure how to unlock this "DFS-UNSET" issue !

Logs are in attachments.

I also tried to start hostapd after that in DFS mode, both requesting channel 100 & 106 in 80MHz band, and in a second attempt using ACS scan.

Both failed as usual.

hostapd logs are also in attachments.

Regards,

Eric
