Intel AX210 not detect 6GHz network on Linux/Android platform

[jsun]

I am trying to get the Intel AX210 working on NXP iMX8 eval board running Android 12 or 13. Following is my setup:

• Android 12 with Linux kernel 5.10, use firmware iwlwifi-ty-a0-gf-a0-59.ucode
• Android 13 with Linux kernel 5.15, use firmware iwlwifi-ty-a0-gf-a0-66.ucode
• Country Region (regulatory domain) is US
• TP-Link AXE5400 (Archer AXE75) Tri-Band 6-Stream Wi-Fi 6E Router

On Android 12, the AX210 is able to connect to 2.4GHz/5GHz network, but not able to detect 6GHz network. I can see the 6GHz frequency is enabled in AX210 (via the "iw list" command), but the AX210 can't detect 6GHz network, and can't scan the 6GHz frequency. 

I know the 6GHz network on the TP-Link WiFi 6E Router is working fine, because I was able to connect to this 6GHz network using the Mediatek Wi-Fi 6E (RZ616) Wireless LAN Card. 

On Android 13, the AX210 driver seems to fail loading the firmware:

Could you please advice which version of Linux kernel supports the AX210 on 6GHz network? Also what version of the "iwlwifi-ty" firmware file to use?

Thank you and Best Regards.

Hello jsun, 

Thanks for your patience. I want to let you know that the Intel 6E AX210 supports Bluetooth-UART only on the selected M.2 1216 soldered-down SKUs, and its platform support is still pending. I recommend you work with your Intel sales representative if you need more details.

As for the AX210 datasheet, you can apply for the Intel RDC access and obtain the Intel® Wi-Fi 6E AX210 (Typhoon Peak 2) External Product Specification (EPS):

• https://www.intel.com/content/www/us/en/support/articles/000058073.html

Regarding the Android operating system, the wireless product specification document only lists Windows and Linux, Android is not officially classified as a support operating system for Intel wireless products. The support for Android is limited. 

Intel Customer Support may offer best-effort help (e.g. Basic troubleshooting on AX210 installation) for Android. For more assistance or support to develop an Intel wireless product on Android, I recommend you also work with your Intel sales representative.

Please keep in mind that this thread will no longer be monitored by Intel.
