On the 5G WiFi chennels for United States there are DFS channels where as on my R6400 on United States there are no DFS channels so I am wondering if this is a bug in the XR500 firemare?
I've seen it more recently with Mfr routers that they are now supporing DFS channels in the USA. Not really a bug, just comething that is gradulally coming to use for consumers. Older Wifi HW will not support these channels was back then they were not approved for use with DFS channels. So older Wifi HW will not work on those channels. They will and should work on the Legacy channels of course. So set your routers accordingly when using older wifi HW.
