Is not displayed the current tx power for wlan 5GHz for hAP AC nor hAP AC lite.
The configuration has default.
In the browser also has the same problem.
It seem to be common issue on all 5ghz devices.
AFAIK, Mikrotik know about this problem. Some time ago I found info about this issue - on this forum or elsewhere in Net… Don’t remember where. Google it.
This a known limitation of all ac-capable chipsets. It is documented at the bottom of this wiki page.
Disappointing.
If the issue is known and will not be resolved, disable the tab.
This makes you look more elegant and shows concern about the product.
