Hello there. I'm trying to find out whether this router can be used as a repeater for a 5ghz network. Being dual band and "high power", one would think it should easily do that, but when I set it as repeater in the GUI, it will only allow me to select among 2.4GHz signals, and won't "see" any 5GHz. There's no version of this menu for a 5GHz host network:

I can manually insert the 5GHz SSID in the "2.4GHz SSID" square, and it will even be saved, but -of course- it won't really connect to it. Apparently the only possible bridge between this router and the access poit is 2.4GHz. See:

In another window of the menu I can turn/off on and set the SSID for an "extended 5GHz". But the fact that it doesn't say "Copy Host SSID" next to it would confirm that the router cannot work as a 5GHz network repeater:

Hence my question: is there a way to configure this router to repeat a 5GHz network?

Thanks for any help.
