EAP225-outdoor endless switching between 2 APs, only some clients
OC200 v1 5.1.7, fast roam not enabled, nor band steering at this time
ER605+SG2008P if it matters
My logs are filling up endlessly, because typically 1 client at a time, and usually only ever 2 of the ~15 or so will switch back and forth between 2 APs, the only two it can see. A second device right next to the one that's flip-flopping is staying stable on 1 AP. Both AP are identical 225-outdoors running same firmware. Signal strengths at the site of flip-flopping are reasonable ~ -70dbm ...as in no reason to switch.

any idea what's going on and how to fix this needless behaviour? Would enabling fast-roaming help or make it worse?
I don't want to reduce power on either AP as they both need what they have to cover the outdoor perimeter.
