Dear crispyoz! Thank you for answer. I saw the document, but as you wrote " Since the warp core driver is not documented or open source it may not implement all functions", it's a current status. Interesting, that in 2016, was a similar issue: https://community.onion.io/topic/1138/connecting-the-omega2-to-wifi-channels-12-to-14-for-non-us-users
I think, RnD team must to know, when we change option country, or option htmode, or option channel parameters in file /etc/confog/wireles, system behavior becomes unstable.
Every 5 seconds the system freezes and does not respond on ping for 1-2 seconds.
My problem, that sometime system wakes up on Channels 10/11/12, but we can not use these channels, according to regulation acts.
In case, that issue hasn't solution, we can not use Onion Omega in our product.
