I just finished setuping a large CAPsMAN installation. 140+ access points (cAP ac, wsAP, etc) and 4 interfaces in CAPsMAN for every AP. I have created 2 bridges, 1 for Staff and 1 for Guests access. Created /23 network for the Guests bridge, /24 for the Staff is enough, and disabled client to client forwarding for both of them. Also tried to make a channel plan as best as i could for 2.4 and 5GHZ, to have as lees interference as possible. The core router is a CCR-1009 and is running at 1% CPU actually.
Until now the network is running ok with up to 100 clients connected.
Since it is the first installation of this size, i was worrying about what will happen when 400+ or more clients will connect. I don't worry about wireless part, but mostly about the core router part. What will you suggest for chopping up the network so I don't have bad surprises?
