Problem with AX200 wireless card in LMDE5

[Alexander_K]

Hello,

I would appreciate any help with a problem I got in LMDE5 with wireless card ASUS PCE-AX58BT, which is based on Intel AX200.
The card worked perfectly with LMDE4, before I upgraded to LMDE5.
After upgrade to LMDE5 wireless network stops working randomly after I wake up the system from sleep, so I have to restart the computer to get the wireless network working again.

The error I find in dmesg output when the network disappears is: iwlwifi 0000:03:00.0: iwl_trans_wait_txq_empty bad state = 0

I searched in the internet and tried so far:

• different iwlwifi driver versions (0.46 provided by Intel and later versions from Debian package for Intel wireless cards)
  working with different kernel versions (now it is 5.10.0-12-amd64)
  disabling power-saving for AX200 in network manager
  deleting pnvm file from /lib/firmware/

without any success.

Again, it worked perfectly before the upgrade to LMDE5.
How can I make it work again?

Thanks in advance,
Alexander.

Hello,

I have the same problem:

terminal output after:
lspci -vv -s 03:00.0

it worked with LMDE4 I used the driver from Intel
https://www.intel.com/content/www/us/en ... eless.html
iwlwifi-cc-46.3cfab8da.0.tgz

If someone has an idea to solve this issue please let me know.

After several more tries, it seems that I found a working combination: kernel 6.0.0-0.deb11.6 and driver iwlwifi-cc-a0-72.ucode. It works for several days now without restart after sleep.

Update: this combination worked only for some time, the problem persists.

Hello, in my hardware is happing same situation.

I found a fix. First I add the next boot kernel parameter:

acpi.ec_no_wakeup=1

Secound:

I set the modules options for iwlwifi:

options iwlwifi power_save=1
options iwlwifi power_level=5


I'm using the laptop 5 days ago without WIFI fail after this tweaks.


EDIT:

Today my laptop newly lost the WIFI connectivity.
