Initially I wanted a "student" WLAN but couldn't assign more than 120 ish laptops to it. MAC limit hit.
Later on I wanted to be able to disable network/web access for groups of laptops/devices. So created lots of WLANs.
Now I have 12 WLANs each with circa 15-30 laptops/devices on.
Now if class A "borrow" class B's assigned laptops I can disable the class B WLAN those laptops belong to.
Now they know and rarely "borrow"! Works for me.
Laptops connect only to the one WLAN they are allowed to join by MAC - users do nothing.
For example buy 15 laptops for RED class, during setup add their MACs to RED acl,, add RED acl to RED WLAN, set windows to connect automatically to RED WLAN. Done.
If you really want to know: also paint a big coloured dot on laptop lid to indicate colour WLAN it belongs to! More for me than them but it all helps with identification.
