If you are looking for a free controller for ruckus without paying license fees, then you'll have to get devices that support unleashed. Just note, R300 does not support unleashed. You would have to stick with R310 or newer... note R310, R500, R600 is only supported until unleashed firmware 200.7.x... R510, R610, R710 are supported with the most current firmware now 200.8.x
