I feel like I am missing something obvious. I managed to figure this out, insofar as this is a firmware related issue. Using firmware version 15.68.7.p18 the 5GHz band is available: https://pastebin.com/aizmeNmn I configured 802.11ac AP with hostapd and it worked correctly. Any newer version of the firmware will report only the 2.4GHz band. Hopefully this saves someone some time. Jan
