I have 5 ruckus 7352 AP's. At times I can have multiple users connected flawlessly to each one...at other times, I can only get 10 or 12 users. If I unplug the AP it will allow connections but in a couple of hours it does the same thing. I have tried to avoid spending the money for zonedirector, but wonder how much it would help with connections. (The 5 AP's are scattered throughout 1 building. 1 in each hall.)
