According to the note, when Marble is set to 160MHz, it should use a DFS channel even when the channel is set to "Auto".
But it's on Channel 42, which isn't a DFS channel and it's the most busiest channel.
160 MHz requires DFS all the time because the non-DFS-spectrum is only 80 MHz wide.
So it appears that your device either is stuck on 80 MHz (maybe your testing device does not support more?) or the Wi-Fi might need an reboot.
The red one and Marble are at 160MHz. We can see they are wider.
The coral color is at 80Mhz or even less (it's narrow).
The central channel of the red one is 58, which is a DFS channel.
The central channel of Marble is 42, which is not a DFS channel.
Yeah. As I said you might need to restart Wi-Fi and check the config within luci.
