DFS channels for ORBI RBR20

Question

This KB seems to indicate that my RBR20 should support DFS channels in the FCC regulatory domain.

https://kb.netgear.com/000060378/Which-Dynamic-Frequency-Selection-channels-does-my-NETGEAR-device-support

However, those channels are not available in the HTTP based admin drop-down. Was support removed? Is there a way to enable DFS support on this ORBI model?

Running firmware 2.7.3.22 with 1 satellite in router mode.

DFS channels are not available for user selecting on any Orbi system. Only channels 36 thru 48. ALL higher channels, usually 149 thru 165 are for the wireless backhaul channels used only by the orbi system.&nbsp;

Interesting.&nbsp; My Wi-Fi Analyzer app isn't showing them beaconing on the DFS channels so it must be using those frequencies with some protocol other than 802.11 a/n/ac...&nbsp;Thanks for the reply

The channels used are described on page 159 of the user manual:
https://www.downloads.netgear.com/files/GDC/RBK50/Orbi_UM_EN.pdf&nbsp;
&nbsp;
US: 5.18 - 5.74 GHz (front haul) and 5.745 - 5.875 (backkhaul)
Europe &amp; Japan: 5.18 - 5.24 and 5.5 - 5.7
&nbsp;
Translated to channel numbers this is:
US: 36 - 48 and 149 - 175 (backhaul)
Europe &amp; Japan: 36 - 48 and 100 - 140 (backhaul)
&nbsp;
There is a note on page 159 about another frequency band becomming available with future firmware (whatever that means).
