I am using channel 52 for the 5Ghz band. AFAIK this applies for the UK.....
- Band A : 5150 - 5350 MHz (channels 36 - 64)
I could well be wrong but Band A above is for internal 5Ghz and Band B, which includes the higher channels, for the UK is for outdoor use.
I also use the Smart Connect function, so I only have one SSID for both bands and the router allocates the device to the preferred radio.
As I understand it you have to select each of the three parts of the AI function to configure and enable them, if you wish.
There is also an addon for the Merlin firmware for ad blocking at the router level.

I have not used it.
