Suddenly wifi (AX211) is unstable and crashes after suspend/resume on Linux

[klausagnoletti]

I have a Samsung Galaxy Book 2 pro with AX211 running Linux. It has done so for the last two years with various distros. No problems what so ever. Until a couple of weeks ago..

First symptom I saw was that there was no wifi but later managed to get it back. Then I reinstalled to Omarchy Linux trying virtually all kernel versions from 6.7 - 6.17. Same problem on all:

- Wifi crashes randomly

- And if it hasn't died already, it will crash after suspension/resume (Not when just doing S2idle but deeper than that).

I have attached a couple of different dmesg log along with other relevant information about the distro and kernel which I hope will provide the information needed to identify the issue - and fix it.

Thanks!

Here's a full kernel log from the system I'm currently using running 6.17.6. The others are just excempts.

Hello klausagnoletti,

Thank you for posting in Intel Communities.

Before proceeding with the investigation, I need to verify the following:

• Is the AX211 WiFi component original/pre-installed on your Galaxy Book 2 Pro?
• Can you download and generate and share an SSU log file from your current Linux setup?

These details, along with your dmesg logs, will enable a thorough analysis of the random WiFi crashes and suspend/resume problems you're experiencing.

Looking forward to your reply.

Best regards

Hi Jeanette and thanks for your reply.

Yes, AX211 is built-in on my laptop. As a temp workaround I've been using a realtek usb wifi thingy so you'll see that in my log too. Just ignore that. 

**bleep** I look forward to hearing your verdict. The current state is quite crippling.

Hi Jeanette

Reading your reply I’m a little unsure whether you need anything else from me. I don’t think so but please let me know if I’m wrong

[klausagnoletti]

@JeanetteC_Intel Could you please give me a reply and a heads up on the status and what I can expect, in terms of timeline for a fix? I am really sick of the current situation so really looking forward to an improvement.

Thanks!

I can confirm this is happening as well recently for me. 

AX211 in a Lenovo Thinkpad X1 Carbon Gen 12 running Linux Mint 22
Linux 6.14.0-1018-oem #18-Ubuntu SMP PREEMPT_DYNAMIC Wed Dec 10 09:33:29 UTC 2025 x86_64 x86_64 x86_64 GNU/Linux

Tried all purges of settings and bluetooth packages along with device resets, etc. The only fix has been to go with a USB bluetooth adapter and I've been solid for the last week since I did that after a month of trying to get the AX211 BT stable again. It had been for a long time. 

I've tried various kernels and latest linux-firmware at https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/ and even older linux-firmware from August 2025 in the hopes that whatever changes were made could have been avoided. No dice. I'm bypassing it now for sanity sake. But, seems like something that should be able to continue to work but it's not.

Hey! Sorry to hear you have the same problem. But also happy as I just got an email from the intel team saying they don’t think it’s a driver issue but related to power management. So if nothing else we’re two to scratch our heads not understanding anything..

[JonathanMergy]

ha! 

If it's not drivers, then maybe something can be corrected in BIOS? It's not any power management settings in Linux is it?

[klausagnoletti]

I did some research with Gemini at some point with the conclusion that it might be related to the various power states around suspend and resume. It ended up suggesting a ton of different things but nothing worked. Also I am NOT an expert in ACPI and power states so idk

[JonathanMergy]

I can tell you I looked into all my options in BIOS a while back to disable or whatever. I could see it could maybe be related to Intel CPU setting in BIOS? I can play with that I suppose. I am not doing really any granular power saving --usually full-tilt power performance mode when plugged-in on the laptop and docked, and that was fine for many months until the last few weeks. 

I have done BIOS updates from Lenovo though and no one really knows what they do - the docs are very sparse. The AX211 linux-firmware drivers haven't really changed either in a long time although the linking in the /intel directory has shifted over the last few months to symlinks vs. specific files

18.852261] Bluetooth: hci0: Found device firmware: intel/ibt-0180-0041.sfi

ibt-0180-0041.sfi for example, is now getting linked to 

which tells me, I think, that be referenced as a common driver for families of chips vs just the AX211

Back in August 2025 linux-firmware there is a different structure it seems where there are files for each separate device. 

Yeah, I dunno. I just hope some updates can correct this. I'm out of ideas and the other bluetooth via USB is solid as this was a month or so ago. 

[klausagnoletti]

Just to elaborate could you talk a abot about exactly what your problem is? How doesn't wifi work? 

I thought it's easier to compare notes if we're completely certain that our problems are the same.

/k

[JonathanMergy]

Sure - not a full crash or drop on the wifi, but bluetooth does drop after suspend or even just after an extended period of time. 

[klausagnoletti]

Allright. Thanks for the elboration. Truth be told I don’t know it bluetooth is affected since I don’t use it much. But I’ll investigate and let you know if I also have that problem.

[klausagnoletti]

@JeanetteC_Intel Could you please provide me more information on why you think this is a power management issue and not a driver issue? Whatever information you can provide makes it easier for me to find a solution. Since, you know, obviously I need this thing fixed no matter what the root cause is. 

[JonathanMergy]

I have disabled Intel AMT in the BIOs and rolled back to an earlier version of linux-firmware for 

ibt-0180-0041.ddc

so will see how it goes since Intel have been of zero help. 

We'll see.
