This (not just the quoted part) was how having two 5GHz radios per unit 'limited' things for you? BTW, it would seem that if you'd wanted clients to "stick" to their AP radio better, you went the wrong direction with those settings, though it's a moot point now.... attempted to adjust the RSSI settings in the WebGUI to allow one unit to hand off the respective clients to the other at a higher dBM/shorter range eg. -47 to -57 vs the default -67 dBM. However, that did not fix the problem.
