Hello, the only channels available to me are the non-DFS ones. My other router is able to select DFS channels, so region shouldn't be a problem I assume. I've been looking around and seeing others with the RT-AX56U can use DFS channels, although all cases I read they had an EU model. I SSH'ed into the router and found out the country code was US, which is also where I'm located. I set the router in AP mode and router mode, hoping it would help. I also tried Merlin firmware, but still no DFS channels.
The router is currently on version 3.0.0.4.384_9428-g7010cec. Made in Vietnam. Manufactured in 2020.
