archer nx600 aggregates in my zone some 4g bands. Non standalone 5g is present, i guess.

But the router shows 100% signal strenght of n78.

This is the only bandwith shown in 5g: manual search is not showing anything else, even if the BTS should have mainly N3.

I barely reach 250Mbit/s, so I suspect that signal strenght is buggy.

Questions: is this value reliable? Does this router work with other 5g bands?

ps. a realtime signal monitor app is not bad idea for positioning or  antenna tuning.
