Hello zqqqqq,

Thank you for contacting Intel Customer Support regarding the driver initialization failure with your Intel Wi-Fi 6 AX210 wireless adapter on OpenWrt.

I've reviewed your dmesg logs and can see that while your AX210 card is being properly detected by the system, the iwlwifi driver is experiencing initialization failures with multiple retry attempts. This is typically related to firmware compatibility or missing firmware components.

Root Cause Analysis: Your current setup shows firmware version 66.f1c864e0.0, but the initialization failures suggest you may be missing the required .pnvm file or using an outdated firmware version for optimal compatibility.

Recommended Solution:

1) Update Firmware Files: Please install the latest firmware for your AX210:

• Main firmware: iwlwifi-ty-a0-gf-a0-89
• Platform file: iwlwifi-ty-a0-gf-a0.pnvm

Download from: https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/

2) Installation Steps:

BASH

1. sudo cp iwlwifi-ty-a0-gf-a0-891 /lib/firmware/
2. sudo cp iwlwifi-ty-a0-gf-a0.pnvm /lib/firmware/
3. sudo modprobe -r iwlwifi
4. sudo modprobe iwlwifi

3) Kernel Consideration: While your kernel 5.10.146 is compatible, consider updating to a more recent stable version (6.19+) for improved driver support.

4) Verification: After installation, check the driver status with:

BASH

1. dmesg | grep -E "iwlwifi|firmware"

The Intel AX210 requires both the main firmware file and the platform NVM file to initialize properly. The retry attempts you're seeing typically indicate the driver cannot complete initialization due to missing or incompatible firmware components.

Please try these steps and let me know the results. If the issue persists after updating the firmware, I'll be happy to provide additional troubleshooting assistance.

Best regards,

JeanetteC.
