Wifi be200 not working after suspend

[Jens1]

Hello, 

Upon boot my wifi works as expected.

Then after it has suspended (and woken up again) it does not work anymore (it doesn't find any networks), the only thing that makes it function is a full reboot.

The error message is something like "Unable to change power state from D3cold to D0, device inaccessible" in dmesg.

I have a Lenovo IdeaPad Pro 5 14IAH10.

I use Ubuntu 24.04.02 LTS.

I used both kernel 6.11.0-26.26 (os default) and 6.15 (latest).

I used firmware versions xx-94.ucode (os default) and xx-98.ucode (latest).

My wifi card is a be200, I think, see below.
`lspci -nnk | grep -A2 0280

01:00.0 Network controller [0280]: Intel Corporation Wi-Fi 7(802.11be) AX1775*/AX1790*/BE20*/BE401/BE1750* 2x2 [8086:272b] (rev 1a)

Subsystem: Intel Corporation BE200 320MHz [Gale Peak] [8086:00f4]

Kernel driver in use: iwlwifi`

Apparently this is a common issue, but I haven't been able to find a solution.

Also command 

`sudo modprobe -r iwlmvm iwlwifi && sudo modprobe iwlwifi iwlmvm` 

does not work.

Any help is greatly appreciated.
Drivers/firmware etc. is new for me so if there is any other information I can provide please let me know.

All the best,

Jens

Hello Jens1,

Thank you for posting in Intel Communities.

To better understand the issue, I would appreciate more information about your system. Please provide the following details so I can proceed with further investigation:

1. Is the Intel® Wi-Fi 7 BE200 a pre-installed component of the Lenovo IdeaPad Pro 5 14IAH10?
2. Was the system originally running Ubuntu, or was it initially equipped with Windows 11?
3. Please share your system configuration by sending us the Intel System Support Utility (SSU) log file. *You can find the Help Guide here.

I look forward to your response.

Best regards

Dear @JeanetteC_Intel,

Thank you for your response. Here are the answers you requested:

1) Yes.
2) I ordered my laptop without OS. So it was running nothing. Now I installed windows and the wifi is working as expected, but I will move back to Ubuntu asap.

3) I included the file you requested, created directly from a bootable usb stick, I think all the information you need is there.

Thank you again,
Jens

In addition to this, I spend another day investigating this. 
Also simulating a 'reboot' after suspend by unbinding/binding the card from the pcie bus does not work. After an unbind a rescan does not find the wifi card.
I hope this information is helpful.

Hi everyone,
I found my solution!
https://bbs.archlinux.org/viewtopic.php?id=293404

For me a fresh ubuntu install (kernel 6.14), a `sudo apt full-upgrade` and the script above did the trick.
Even if sudo modprobe -r iwlmvm iwlwifi gives an error it still works
