Hello,
I am working on Jetson Nano boards. I would like to connect two boards together with AX200 wifi module.
One is configured in hostspot mode and the other one is the client connected to the hostspot.
Kernel Version: 4.9.140-tegra aarch64
Ubuntu distribution: Bionic
The idea is to used hostapd and wpasupplicant daemon to set up the module and connect the card together.
Wpa_supplicant and hostapd version V2.6.
I install all the drivers from intel and follow this tuto. https://wifi.hypergeek.net/you-too-can-have-a-sub-200-11ax-client/
So I can see the wlan phy with ifconfig command line.
When I try to launch hostapd in ax mode with your module I have the following mistake.
ACS: Possibly channel configuration is invalid, please report this along with your config file. ACS: Failed to start wlan0: AP-DISABLED hostapd_free_hapd_data: Interface wlan0 wasn't started
Could you help to set up correctly hostapd ?
Best Regards

Hi
As far as i know the AX200 is not intended/can not be used as AP.
If you type "iw list" you should get a list of the capabilities of your
card.
On an ath9k based card this looks something like this:
valid interface combinations:
* #{ managed } <= 2048, #{ AP, mesh point } <= 8, #{ P2P-client, P2P-GO
} <= 1, #{ IBSS } <= 1,
total <= 2048, #channels <= 1, STA/AP BI must match, radar detect
widths: { 20 MHz (no HT), 20 MHz, 40 MHz }

Hello Matthias,
The AX200 module seems to support AP mode it works with 2.4GHz Wifi 802.11n mode, I tested it. But maybe it could not support this mode in 802.11ax.
Please find in attach file the log of the iw list command launch on the Jetson Nano.
Best regards.

2.4 GHz should be OK - 5 GHz is generally limited on those devices due
to regulatory restrictions.

Hello Johannes,
What you mean by regulatory restrictions?
Hardware restriction ?
Software restriction ?
Law restriction ?

There are legal restrictions on spectrum use, especially in the 5Ghz
range. Which means additional effort must be put into both hardware and
software to satisfy those restrictions. And perhaps that effort was not
considered cost effective for the AX200.

Martin,
Interesting. I knew there were issues for 802.11ax in the ISM band outside of the ones currently used for wifi, but it seems the issues extend to the current 5GHz band as well.

To be clear, I have no idea about this specific device or case. But
802.11h is an example of behavior required for legal/regulatory
reasons.
