I have already created another thread concentrating on the status of the WiFi problems found in hAP ac^2 in the following thread.
Even applied the most recent RC (V6.42RC52), although the speed for 5G WiFi has already been increased from 20Mbps to 90Mbps, which is much below our expectations. We want the device to be capable to download file at a steady and stable rate of 500Mbps over at least an hour and not just few mini-seconds..
