Is it possible to enable DFS/TPC 5Ghz wifi channels on the RT-AC68U B1 router running Merlin firmware or does this router not support these additional channels physically? Almost all of the DFS/TPC channels are allowed in my country but none of them are listed when choosing the 5Ghz wifi channel. If it's possible to enable these is there any information on how to do so?

What router model do you actually have? Your past posts are contradictory. Is it an RT-AC66U, and RT-AC68U or an RT-AC66U_B1? Is the "B1" part of the model name or just the hardware revision?

What firmware version is it running?

What country was it purchased from?

If DFS channels aren't listed, then they aren't supported, and that cannot be changed.
