Thanks for your mail, but very pity, after checking, it doesn't as well. May you test it on your board?

Its a AGN card, so it supports 5GHz.

Channel 104 is a DFS channel which is not allowed in country US.
Please use a non-DFS channel like 36/40/149 and then try (or)
change the country_code which has 104 allowed :-).

You can also use "iw reg get" to get list of bands allowed, all the bands
marked with passive-scan are not allowed in AP mode unless we implement
full DFS functionality (CAC) and make the channel usable.

Also use a separate thread, dont post in other threads.
