put 3 hAP lite or not, or 3 wAP, setup capsman on another router ex. rb3011. Bingo!
http://routerboard.com/RB952Ui-5ac2nD is much better than hAP lite as it has 2,4 and 5 GHz radios so it means better coverage and weaker signal.
i have tested and compared hAP lite vs hAP ac lite and i think the difference between this 2 is not as dramatic, i think the hAP lite is a very very good device specially taking in count the cheap cost
technically the 2,4ghz radio, is the same but the hAP lite shows a little less tx power and rx sensitivity, about 1-2 dbm in both ways
technically the cpu, is the same but the hAP lite has 20% less performance because use ddr1, while hAP ac lite use ddr2
32mb of ram on hAP lite is enough for most configurations
the biggest plus of hAP ac lite is the second radio, is a single chain 5ghz radio, with good tx power to complement the 2.4ghz radio
