I have already done tests based on hAP ac^2 and wAP ac, as follows:
Since the chipset of hAP ac^2 is similar to that of cAP ac, I do believe you can take a look at them when you do comparisons. Based on the figures presented, it definitely and clearly shows that wAP ac is much better and hAP ac^2. Since there are problems with the wireless part of IPQ401X including hAP ac^2 and cAP ac and others. It seems that MikroTik put their efforts on 60G link (using IPQ4019 chipset, which is the same family of IPQ4018). Please pay attention to the Retr (packets retry count) of Listing 6, it is too high and unacceptable. For more details about hAP ac^2, please see the following thread:
